Getting Started

There are basically two ways to make a web page. The first way is to create the page(s) offline and then upload them to your Internet Service Provider (ISP) via FTP. The second way is to create your web page(s) online using a Telnet program by accessing your UNIX account, if you have one.

If you are creating your web page(s) offline, do so in any text editing or word processing document. Make sure that when you save your document, you save it as a "text", "plain text" or "text only" document. Otherwise it will not be read properly by a web browser. Once you have created your page(s), you will need to contact your ISP about how to go about uploading them to your server.

If you have a UNIX account, you can create your web page(s) online. You first need to get a program that can access your UNIX account. I recommend Telnet for the Mac orEwan for Windows 95/98.

Once you can access your account, you need to make a new directory called "public_html". You can do this by typing:

mkdir public_html

After this, change your directory to this new directory called "public_html".

cd public_html

If you want to, you can make other directories, one for all the web pages that you make, and one for all of the graphics that you have. Follow the same steps as above to do this.

Next, you need to think of a filename for your page (this is not a title, but what will be in the URL). A common filename for a main web page, is "index". Once you've decided on this, add ".html" to the end of it. Then type (i.e.)

pico index.html

Of course, use your page's filename, instead of this one. Next, you need to gain some knowledge of the many HTML commands. Lucky for you, I've already gotten some of the basic commands for you. Follow the index below, to decide what to put on your page, and how to do it. Once you've gotten started, exit your page. You can do this by pressingcontrol-x. Then you need to type:

chmod 744 index.html

Only do this with the filename of your page. You only need to do this the very first time that you leave your web page. This command will make sure that nobody else can delete your page. You will need to do this to any other pages that you make in the future. Then, look at your page on the WWW. Lets say that your server is "www.domain.com", your username is "username", and the name of your page is "index.html". The URL would normally be:

http://www.domain.com/~username/index.html

However, you will need to contact your ISP for your URL.

If you have made separate directories for pages and graphics, then you need to include that in the URL also. Lets say that you made a directory for all of your web pages, called "Pages". The new URL would be: http://www.domain.com/~username/Pages/index.html

Title

The first thing to put on your web page, is a title. The title is what will show up in the very top of the window. Let's say that your title is going to be "John Doe's Web Page", you would type:

<title>John Doe's Web Page</title>

In HTML, every command is surrounded by <'s, and >'s. And in most commands, you need to tell the web browser when to end this command. You do this by putting a back slash (/) in front of the ending command, as in above. Since HTML isn't case sensitive, <title> is the same as <TITLE>, which is the same as <TiTLe>. Next, you need to decide what you want to put on your page. Text, links, graphics, and text fields, are just a few ideas. Follow the table of contents above to decide how, and what to put on your page.

Text

Headings

HTML has six levels of headings, numbered 1 through 6, with 1 being the largest. Headings are displayed in larger, or smaller fonts, and usually bolder. If you wanted to type "Hello", this is what you would type for each heading, and what the outcome is:

<h1>Hello</h1>

Hello

<h2>Hello</h2>

Hello

<h3>Hello</h3>

Hello

<h4>Hello</h4>

Hello

<h5>Hello</h5>

Hello

<h6>Hello</h6>

Hello

Paragraphs

Whenever you have more than a sentence of writing, you should have paragraphs. Personally, I don't see what the difference is, but I do it anyway, because then I can find a certain spot better when programing. To Make a paragraph of "This is a web page. How do you like what I've done? Please e-mail me with any suggestions at a@a.com", type:

<P>This is a web page. How do you like what I've done? Please e-mail me with any suggestions at a@a.com</P>

The outcome is:

This is a web page. How do you like what I've done? Please e-mail me with any suggestions at a@a.com

Lists

There are two types of lists that you can make in HTML, dotted, and numbered. To make a dotted list of: red, orange, green, blue, purple, black, and brown, type:

<UL>
<LI> red
<LI> orange
<LI> green
<LI> blue
<LI> purple
<LI> black
<LI> brown
</UL>

The result is:

• red
• orange
• green
• blue
• purple
• black
• brown

To make a numbered list of: red, orange, green, blue, purple, black, and brown, type:

<OL>
<LI> red
<LI> orange
<LI> green
<LI> blue
<LI> purple
<LI> black
<LI> brown
</OL>

The result looks like:

1. red
2. orange
3. green
4. blue
5. purple
6. black
7. brown

Forced Line Breaks

There are many cases in which you want to end typing on one line, and start on the next. To do this, you can use a simple HTML command. This is one of the few commands that you don't have to put an ending command on. Let's say that you wanted to say "Hello, how are you?", but with each word on a separate line. All you have to type is:

Hello,<BR>how<BR>are<BR>you?

The outcome is:

Hello,
how
are
you?

Horizontal Rules

Every now and then, you might want to have a horizontal rule, or line in your page. Horizontal rules can be many different sizes and lengths. You can also have the line be solid black, by typing NOSHADE. Here are several examples of sizes and widths, and what the outcome is:

<HR SIZE=1 WIDTH=100%>

Character Formatting

You may want to format some of your text differently than others using text styles. There are several types of styles of text that you can use: bold, italic, underline, strikeout,^superscript, _subscript, teletype, and blinking text are examples. To do these styles, surround your text with the following commands:

<b>, </b> for bold

<i>, </i> for italic

<u>, </u> for underlined

<strike>, <strike> for strikeout

^, for ^superscript

_, for _subscript

<tt>, </tt> for teletype

<blink>, </blink> for blinking text (very annoying)

You can also mix styles together like this!

Linking

URLs

When you make a link, you are making colored text or even a graphic (talked about later). When somebody clicks on this text, it will take them to another web page, or possibly a certain section of a web page. Let's say that you wanted to make a link from your web page, to Yahoo!. The URL of Yahoo! is:
http://www.yahoo.com
To do this, you would type:

<A HREF="http://www.yahoo.com">What ever text that you want to be colored goes here</A>

The result would be:

What ever text that you want to be colored goes here

You can go ahead and try it if you want to.

Links to Specific Sections

Sometimes, you might want to have a link that will take you further down a page, or to a certain section of another page. An example of this is the index to this web page. You click on the colored text, and it takes you to that section. To do this, you need to do two things. The first, is to make the link, and the second, is to make where the link will lead to.NOTE: You cannot make links to specific sections within a different document unless either you have write permission to the coded source of that document or that document already contains in-document named links. 
1) To make the actual link, think of a name for the certain spot. Let's say you are going to call it "spot". If this certain spot is on the same page that the link is, you would type:

<A HREF="#spot">Colored Text

Otherwise, you would add "#spot" to the end of the URL.
2) Now, you need to make where the link will take you. Go to the spot where you want the link to take you, and type:

<A NAME = "spot">

Mailto Links

Most people like to have a link on their web page that automatically sends e-mail to an address. If you want to do this, and your name is Dan, and your e-mail address is a@a.com, type:

<A HREF="mailto:a@a.com">Dan</a>

Here is the result of typing this:

Dan

Graphics

Putting Images On A Page

On almost EVERY web page on the net, there is some kind of graphic. I would HIGHLY RECOMMEND that you have AT LEAST one picture on your page. There are mainly two kinds of ways to have graphics on your web page. The first, is to use a graphic that is on another web page somewhere on the web. The second, is to upload the graphic to your own account. Personally, I prefer to use the upload method. If you are using the other way, there is always a chance that the person who made that page will decide to delete that graphic. Then a symbol with a circle, square, and triangle will appear where the graphic was supposed to be, sometimes it will look like it has been torn through the middle:

1)
To display a graphic on some one else's page, you need to find the URL. To do this, I recommend that you have Netscape Navigator. Right click or click and hold down on the graphic, until a menu comes up. Choose "View this Image". Then , copy the URL that appears at the top of the screen, in the "location" box. Let's say that the URL was: http://www.infhost.com/members/web/Images/pic.gif You would type:

<IMG SRC="http://www.infhost.com/members/web/Images/pic.gif">

The result is:

2)
To display a graphic that is in your account, all you have to do is type in the filename. If you didn't make separate directories for graphics and pages, then you just need to type the graphic's name.(i.e. <IMG SRC="pic.gif">

Alternate Text for Images

Some World Wide Web browsers cannot display images. Some users turn off image loading even if their software can display images (especially if they are using a modem or have a slow connection). HTML provides a command to tell readers what they are missing on your pages. The "ALT" attribute lets you specify text to be displayed instead of an image. For example:

<IMG SRC="pic.gif" ALT="How to make a web page">

In this example, "pic.gif" is the picture of a sign. With graphics-capable viewers that have image-loading turned on, you see the graphic. With a non-graphic browser or if image-loading is turned off, the words "How to make a web page" is shown in your window. You should try to include alternate text for each image you use in your document, as it is a courtesy for your readers.

Animated Graphics

Some people like to put animation on their web pages. It actually is not that hard. Here is some background history. Most GIFs over the years have only one image per file. According to "technical specifications from 1987", a GIF could have had more than one image per file, making it like a slide show presentation and not a single image. However, most programs that work with GIF are designed around the idea of one image per file. So the multi-image aspect of GIFs was forgotten. In 1989, they added timing and various other abilities to the GIF format, including transparency. Nobody used these new additions either. Then the Web took off. Transparency and interlacing became features people wanted to use and software companies began supporting those features. In order to have animation on your web page, you need to download a program that was made to fit more that one GIF in a file. I recommend GifBuilder for the Mac. Windows users can go here to download another program. Here is one example of a small animation:

Background, text, and link Color

On most pages, you want to have a specific color for the background, text, unvisited links, visited links, and active links. In order to do this, you need to find the code number for the specific color that you are looking for. Here is a HUGE list of code numbers, and here is how you would display this in your page. NOTE: Type these ONLY right below your title. NOTE: You must have the "#" sign before the actual code.

• <body bgcolor="#code">for background color
• <body text="#code">for color of text (all non-links)
• <body link="#code">for color of unvisited links
• <body vlink="#code">for color of visited links
• <body alink="#code">for color of active links (while being selected)

You can also string two or more of these commands together:

<body bgcolor="#000015" text="#000020" link="#000050" vlink="#7a7777" alink="#8f8e8d">

Background Graphics

Instead of having a solid color as a background, you might want to have one graphic that repeats over and over to create a background. Here are several places that you can go to find background graphics. The text that you would type in for a background called "bk.gif" would be:

<body background="bk.gif">

Linking with graphics

Sometimes on your web page, you might want to have a graphic that is a link. This is quite simple, since you just mix the two commands of linking, and displaying graphics. Here is an example of a graphic that leads to Yahoo:

You can also have a text link next to the graphic that leads to the same place.

Yahoo!

Here is what you would type in for, first the plain graphic-link, and second, the graphic-link with text:

<A href="http://www.yahoo.com"><IMG SRC="http://www.infhost.com/members/web/Images/yahoo.gif"></A>

<A href="http://www.yahoo.com"><IMG SRC="http://www.infhost.com/members/web/Images/yahoo.gif">Yahoo!</A>

Image Maps

Before you create an image map, you need to make sure that your server supports them. Then, you can follow these steps. First, you need to create an image. Draw a picture with sections that could lead to certain places. Second, you need to create an image map file. There are several programs that can do this for you. I recommend WebMap, for the Mac.You can go to Yahoo's Image Map Directory for others. 

Fill-out Forms

Getting Started

Fill-out forms let a reader return information to a Web server for some action. For example, suppose you collect names and email addresses so you can email some information to people who request it. This processing of incoming data is usually handled by a script or program written in Perl or another language that manipulates text, files, and information. If you want to, you can write this program yourself, but I have no idea how to do it. I would check with your server. I know that many servers have scripts available for its users. Let's pretend that the one that I'm going to use is called "fb.pl". This will send a response to your fillout form directly to your email address. NOTE: This script is not real, it is just an example. Check with your ISP to see if they have built-in scripts.

Form Method/Action

The first thing that you type for your guestbook is the Form Method and Action. This is where you enter the Perl script. Most servers and Internet Providers have scripts like this that they provide for you. Check with yours. You cannot have any kind of forms without having a script. The address of the one that I'll be using is:
http://www.domain.com/cgi-bin/fb.pl. If you would like the response sent to your email address, and the address is "a@a.com", you would type this for the first two lines:

<FORM METHOD="POST" ACTION="http://www.domain.com/cgi-bin/fb.pl">
<INPUT TYPE="input" NAME="recipient" value="a@a.com">TO:<P>

Here is what it will look like:

Next, you need to decide what questions that you want to ask, and what you will use to ask them. Before you start, though, you might want to check with your server to see if they have any questions that you MUST ask. I know with some ISPs, you must ask what their email address is, their first name, their last name, and what the subject of their question is. You can use single or multiple text fields, larger fields, checkboxes, radio buttons, pull-down lists and scroll-down lists.

Single or multiple fields

In your guestbook, you might want to ask questions that have a single one word answer. To here is what you would type to have four fields that ask for an email address, a first name, a last name, and a subject:

<INPUT TYPE="input" NAME="from">Your Email Address<P>
<INPUT TYPE="input" NAME="firstname">Your First Name<P>
<INPUT TYPE="input" NAME="lastname">Your Last Name<P>
<INPUT TYPE="input" NAME="subject">Subject<P>

Here is what the result is:

Your Email Address

Your First Name

Your Last Name

Subject

Larger Fields

I would recommend that you have one larger field at the end of your guestbook for comments. You first need to decide how many columns and rows that you want to have. Let's say that you want to have 7 rows, and 45 columns. Here is what you would type:

Please place any questions or comments here:
<TEXTAREA Rows=7 Cols=45 NAME="suggestions"></TEXTAREA><P>

Here is what the result looks like:

Please place any questions or comments here:

Checkboxes

Let's say that you wanted to ask a question like "What are some things that you like to do?" You could have a list of things with checkboxes. If you wanted the list to be: Watch TV, play on the Internet, read a book, play sports, and study, you would type:

What are some things that you like to do?

<INPUT TYPE="checkbox" NAME="like" VALUE="TV">Watch TV<P>
<INPUT TYPE="checkbox" NAME="like" VALUE="internet">Play on the Internet<P>
<INPUT TYPE="checkbox" NAME="like" VALUE="read">Read a book<P>
<INPUT TYPE="checkbox" NAME="like" VALUE="sports">Play sports<P>
<INPUT TYPE="checkbox" NAME="like" VALUE="study">Study<P>

The result:

What are some things that you like to do?

Watch TV

Play on the Internet

Read a book

Play sports

Study

Radio Buttons

If you ever want to ask a question with one answer, you can use radio buttons. If you wanted to ask "What WWW browser are you using right now?", and you wanted to have the choices Netscape Navigator 4.x, Netscape Navigator 3.x, Netscape Communicator, Mosaic, and Microsoft Explorer, you would type:

What WWW browser are you using right now?

<INPUT TYPE="radio" NAME="browser" VALUE="Navigator 4.x">Netscape Navigator 4.x<P>
<INPUT TYPE="radio" NAME="browser" VALUE="Navigator 3.x">Netscape Navigator 3.x<P>
<INPUT TYPE="radio" NAME="browser" VALUE="Communicator">Netscape Communicator<P>
<INPUT TYPE="radio" NAME="browser" VALUE="Mosaic">Mosaic<P>
<INPUT TYPE="radio" NAME="browser" VALUE="Internetex">Internet Explorer<P>

The Result:

What WWW browser are you using right now?

Netscape Navigator 4.x

Netscape Navigator 3.x

Netscape Communicator

Mosaic

Internet Explorer

Pull-Down Lists

Another way to ask a question with only one answer is to use a pull-down menu. You can use the SELECTED command to have an option besides the first be selected, as you will see below. If you wanted to ask "What is your favorite color?", and you wanted the list to be of red, yellow, orange, green, blue, purple, black, and brown, with black selected, you would type:

What is your favorite color?
<SELECT NAME="color">
<OPTION>Red
<OPTION>Yellow
<OPTION>Orange
<OPTION>Green
<OPTION>Blue
<OPTION>Purple
<OPTION SELECTED>Black
<OPTION>Brown
</SELECT><P>

The outcome is:

What is your favorite color?   Red Yellow Orange Green Blue Purple Black Brown

Scroll-Down Lists

Some times, you might want to have a scroll-down list on your page. With this, you can decide whether or not you want people to be able to select more that one item. If you do have it with more that one items, the user has to hold down the command or shift key. You can also decide how many of the lines you want visible. Below are two lists of the same things. In the first one, you can only select one item, and it is showing three lines. In the second one, you can select one or more items by holding down command or shift . The second list is showing four lines. The question is "What is your favorite video game system?" The answers are: Nintendo 64, Sony Playstation, Sega Dreamcast, or arcade video games. The text that you type for each list is above the actual list.

What is your favorite video game system?
<SELECT NAME="video game" SIZE=3>
<OPTION VALUE="nintendo64">Nintendo 64
<OPTION VALUE="playstation">Sony Playstation
<OPTION VALUE="dreamcast">Sega Dreamcast
<OPTION VALUE="arcade">Arcade Games
</SELECT><P>

The outcome is:

What is your favorite video game system?

  Nintendo 64 Sony Playstation Sega Dreamcast Arcade Games

The second outcome is:

What is your favorite video game system? (Hold shift to select more that one)   Nintendo 64 Sony Playstation Sega Dreamcast Arcade Games

Reset Form

On most page that have fill-out forms, there is a reset button at the bottom of the form, next to the "submit" or "send" button. To have a reset button, just type:

To reset the all of the forms, press this button:<INPUT TYPE="reset" VALUE="Reset">

The outcome is: (try it!)

To reset the all of the forms, press this button:

Submit Entry

When you are all finished with everything, you need to make a button so that people can submit their entry. To do this, type:

To submit your choices, press this button:<INPUT TYPE="submit" VALUE="Submit">

The result is: (NOTE: Please don't click this button. It has been disabled and will not work.)

To submit your choices, press this button:

NOTE: At the very end of your form, you must type </FORM> or your forms won't work!!

Frames

What are Frames?

Frames basically split your window in to sections. You can display two or more web pages at a time with frames. You don't necessarily have to have whole pages in a frame. You could just have graphics, too. If you are really interested in putting frames on your page, I recommend that you go here to Sharky's Netscape Frames Tutorial and read the lessons.

Java

What is Java?

Java is a simple, robust, object-oriented, platform-independent multi-threaded, dynamic general-purpose programming environment. It's best for creating applets and applications for the Internet, intranets and any other complex, distributed network.

Programming in Java

I do not know how to program in java. However, it is a very useful language if you know how to use it. If you think that you would like to begin learning the java language, an excellent tutorial can be found here.

Just because I don't know how to program in java, doesn't mean that I don't use it. I love java. It can add so much to a web site. If you really don't want to learn java, but would like to use it on your web pages, I would suggest using free java scripts that can be found around the web. One such web site can be found here at Sharky's JavaScript Answers.

HTML khoản

Các đoạn văn bản được định nghĩa với các từ khóa <p>.

Lưu ý: Các trình duyệt tự động thêm một dòng trống trước và sau khi một đoạn.

Đừng quên Tag Cuối

Hầu hết các trình duyệt sẽ hiển thị HTML, một cách chính xác ngay cả khi bạn quên thẻ kết thúc:

Ví dụ trên sẽ làm việc trong hầu hết các trình duyệt, nhưng không dựa vào nó. Quên thẻ kết thúc có thể tạo ra kết quả bất ngờ hoặc các lỗi.

Lưu ý: Tương lai phiên bản của HTML sẽ không cho phép bạn bỏ qua các thẻ kết thúc.

Dòng Breaks HTML

Sử dụng thẻ <br /> nếu bạn muốn có một ngắt dòng (một dòng mới) mà không cần bắt đầu một đoạn mới:

Các /> <br yếu tố là một phần tử HTML có sản phẩm nào. Nó không có thẻ kết thúc.

- hoặc <br />

Trong XHTML, XML, các phần tử không có thẻ kết thúc (thẻ đóng) không được phép.

Ngay cả khi công trình - trong tất cả các trình duyệt, viết <br /> thay vì làm việc tốt hơn trong các ứng dụng XHTML và XML.

HTML Output - Lời khuyên hữu ích

Bạn không thể chắc chắn làm thế nào HTML sẽ được hiển thị. Màn hình lớn hay nhỏ, và thay đổi kích thước cửa sổ sẽ tạo ra kết quả khác nhau.

Với HTML, bạn không thể thay đổi sản lượng bằng cách thêm vào không gian phòng, hay dòng thêm trong mã HTML của bạn.

Các trình duyệt sẽ loại bỏ các không gian bổ sung và các dòng thêm khi trang được hiển thị. Bất kỳ số lượng các dòng được tính là một dòng, và bất kỳ số lượng của không gian tính là một không gian.

(Ví dụ này chứng tỏ một số vấn đề định dạng HTML)

Tag HTML <font> không nên được sử dụng

Thẻ <font> bị phản đối trong HTML 4, và loại bỏ từ HTML5.

World Wide Web Consortium (W3C) đã loại bỏ các thẻ <font> từ khuyến nghị của mình.

Trong HTML 4, style sheets (CSS) nên được sử dụng để xác định các thuộc tính bố trí và hiển thị nhiều yếu tố HTML. 

Ví dụ dưới đây cho thấy làm thế nào HTML có thể tìm bằng cách sử dụng thẻ <font>:

Safe Web Màu sắc?

Một vài năm trước đây, khi máy tính được hỗ trợ tối đa 256 màu sắc khác nhau, một danh sách của 216 "Màu sắc Web an toàn" đã được đề xuất như là một tiêu chuẩn Web, dành 40 màu sắc hệ thống cố định.

216 cross-trình duyệt bảng màu được tạo ra để đảm bảo rằng tất cả các máy tính sẽ hiển thị màu sắc chính xác khi chạy một bảng màu 256.

Đây không phải là quan trọng ngày hôm nay, vì hầu hết các máy tính có thể hiển thị hàng triệu màu sắc khác nhau. Dù sao, đây là danh sách:
