HTML overview

HTML, or HyperText Markup Language, is a world wide markup language that allows a user to create his or her own web page. While HTML is a fairly easy to learn
markup language, it does involve several hundred commands to learn and memorize.

With HTML, the user creates tags; tags are anything between the less-than and the greater-than signs. Using the tags, this identifies where the commands begin and end. For example, <b>Bold Text</b> tells the browser that <b> is the beginning of the bold text statement that will turn anything after that tag bold; once the browser hits </b> the browser then turns the bold text statement off, allowing for only specific text to be bold

On this page we have created a list of HTML commands, which can be used in web pages to change text, add different features, and apply several other different effects.

HTML COMMANDS

 - HTML Tag that allows you to implement comments into your HTML Code, which would be hidden to the average browser.

Example:

Preview:

<A> -HTML tag that which allows aspects of your web page to be anchored, such as a link <A HREF= "Http://www.computerhope.com">

Example:

<A HREF="http://www.computerhope.com">Computer Hope</A>

Preview:

Computer Hope

<ABBREV> - New HTML tag available with HTML3.0 which allows you to abbreviate words on your web page automatically.

Example:

<ABBREV>Contained words will be abbreviated.</ABBREV>

<ACRONYM> - Like ABBREV, also a new command with HTML 3.0 that displays the text acronym when mouse is highlighted over text.

Example:

<ACRONYM TITLE="Free computer help and support">Computer Hope</ACRONYM>

Preview:

Computer Hope

<ADDRESS> - Command that changes the format of the text to signify an address. This is generally used with e-mail addresses. However, can also be used for a street address.

Example:

<ADDRESS>support@computerhope.com</ADDRESS>

Preview:

support@computerhope.com

<APPLET> - Command used with Netscape to implement a Java application into a web page.

Example:

<APPLET CODE="myapplet">Click here to see Java applet.</APPLET>

Preview:

View COOL FEATURES to see Java applets.

Additional information:

To insert JavaScript into your web page you would use the <SCRIPT> tag.

<AREA> - Defines a section of an image that the user can click on. This allows you to have one image with multiple clickable links within it.

Example:

<AREA CORD="10,20,150,125" SHAPE=rect HREF="http://www.computerhope.com">. The CORD that is used in this example tells the computer where on the image the location for the link is when your mouse is over that CORD; then, if clicked, it will go to the
web page. The SHAPE tells the browser it is able to click and what type of shape the portion area is.

Example:

Additional information:

The 100,5,155,55 are telling the browser where the link is. 100 representing how far from the left you want the link to start. 5 representing how far from the top you want the link to start. 155 representing how far from the right you want the link to end. 55 representing how far from the bottom you want the link to end.

Preview:

On the below image, move your mouse over the O and notice how that is the only link on the image; clicking on that O would take you to our main page.

<B> - Tells the browser to display the text within the HTML tags to be bold.

Example:

<B>This text would be in bold</B>

Preview:

This text would be in bold

<BANNER> - HTML Tag used with HTML 3.0 used like scrolling but does not scroll with the rest of the HTML document.

Example:

<BANNER>Welcome to Computer Hope</BANNER>

<BASEFONT> - Tells the browser the new set for the font size can be 1 through 7. The default value is 3.

Example:

<BDO> - Tells the browser how to display the text; for example, using the DIR attribute you can make it go left to right using DIR=ltr Example:

<BDO DIR=rtl>Makes text go opposite way<bdo> this just causes the text to go right to left; this tag is usually used for international purpose.

Example:

<BDO DIR=ltr>This text would be going from the left to the right.</BDO>

Preview:

This text would be going from the left to the right.

<BGSOUND> - Allows you to play your music on your web page with Internet Explorer; will not work with people browsing with Netscape. You may also add the loop= statement to specify how many times you wish the sound to play.

Example:

Example:

<BIG> - HTML 3.0 tag that allows your text to be BIG.

Example:

<BIG>This text would be big.</BIG>

Preview:

This text would be big.

Example:

<BIG><BIG>This text would be bigger.</BIG></BIG>

Preview:

This text would be bigger.

<BLINK> - HTML tag that can be extraordinarily annoying when viewing a web page. Internet Explorer does not incorporate this tag, but still is available with Netscape Navigator.

Example:

<BLINK>This text would be blinking if compatible browser</BLINK>

Preview:

This text would be blinking if compatible browser.

<BLOCKQUOTE> - Command that allows you to indent your lines one inch from the left hand side. Instead of using this command to indent text or other objects we suggest using
CSS. See document CH001034 for
additional information and help.

Example:

<BLOCKQUOTE>This would be one tab from the left hand side of the page or the table cell it is in.</BLOCKQUOTE>

Preview:

This would be one tab from the left hand side of the page or the table cell it is in.

<BODY> - Command that should be located towards the top of your HTML code. This tag is used to specify the color of the text, the links, the background color and the background image.

Example:

background="back.gif" - This is telling the browser that you wish to have an image in the background. The page you are currently viewing is one image tiled down to create the appearance of a side column. If you
wish to create the same effect with your web page, you must remember to create this image at least 1040 pixels in length; this will allow your web page to be displayed properly with all resolutions up to 1024 x 768. A common mistake we have noticed is other web masters creating images at 640/650 pixels in length, which makes the image tiled when viewing web pages over 640 x 480. For additional information on video resolutions, see our Video Card Page.
bgcolor="#FFFFFF" - This specifies we wish to have a white background; while this is not necessary when having an image as a background, it generally creates a better transition for our page, considering it contains mostly white. #FFFFFF is the hexadecimal for the color white. In this tag you can also specify white instead of the hexadecimal value.
text="#000000" - This tells the browser to display all text black unless otherwise specified. #000000 is the hexadecimal for the color black. This
tag will also allow you to specify the color by spelling it out.
link="#000000" - Specifies that links on the page that have not been visited should be black. If this tag is not specified the default color will be used, which usually is a blue. #000000 is the hexadecimal for the color black. This tag will also allow you to specify the color by spelling it out.
vlink="#000000" - Specifies the color of the links that have been visited. If this tag is not specified the default color is generally purple. #000000 is the hexadecimal for the color black. This tag will also allow you to specify the color by spelling it out.
alink="#000000" - Specifies the color when the link is active; this is generally specified for newer browsers, old browsers under 3.x do not have any effect on this code. The active link only changes when clicked (this is not used to change the color when the mouse is moved over the link). #000000 is the hexadecimal for the color black. This
tag will also allow you to specify the color by spelling it out.
topmargin="0" - Tells the browser not to have a margin on the top of the browser window (this is generally a small white space on the top of the page. We have noticed that Netscape and older versions of Internet Explorer do not completely eliminate the margin even if the value is zero.
leftmargin="0" - Tells the browser not to have a margin on the left side of the browser window (this is generally a small white space on the top of the page. We have noticed that Netscape and older versions of Internet Explorer do not completely eliminate the margin even if the value is zero.

Preview:

The above example is the body tag we are currently using on this page.

<BR> - Tells the browser that this is the end of the line and to start a new one.

Example:

<BR>

Preview:

The <BR> HTML tag returns once (down one line), another applicable HTML tag is <P ALIGN="LEFT"> Paragraph here.</P> When this tag is used this will begin a new paragraph.

<CENTER> - Tells the web browser to center the text according to the page, table, or frame.

Example:

<CENTER>This text would center on the page.</CENTER>

Preview:

This text would center on the page.

<CITE> - Similar to the blockquote command this command enables you to cite text and displays itself in an italic font.

Example:

<CITE>This text is in italic and is a cite from somewhere else.</CITE>

Preview:

This text is in italic and is a cite from somewhere else.

<CODE> - Allows the user to specify code or a command that generates a different type of font to signify the code.

Example:

<CODE>dir - command used in DOS to list files.</CODE>

Preview:

dir - command used in DOS to list files.

<DEL> - Allows a user to delete text within an HTML document without actually removing it using a strike through.

Example:

This is an example of <del>removed</del> text.

Preview:

This is an example of ~~removed~~ text.

<DD> - Specifies to the browser that a definition is going to placed in the code. The browser will then indent the paragraph (x 2) and change the font of the characters.

Example:

<DD>Definition goes here.</DD>

Preview:

        Definition goes here.

<EM> - Tells the browser that this is important text and it will make it emphasized.

Example:

<EM>Computer Hope</EM>

Preview:

Computer Hope

<EMBED> - Used with Netscape Navigator, which implements a third-party file such as a movie or sound clip or some special embedded object on the web page. Example: <embed src="mydoc.dcr">

Example:

<FONT> - Allows you to have multiple fonts, colors and sizes.

Example 1:

<FONT size=+2>This text would be two times bigger.</FONT>

Example 2:

<FORM> - Allows you to obtain input from visitors; you can see an example of this by viewing the source in our e-mail page.

<FRAME> - Netscape HTML extension that allows you to use frames on the web page, being able to make bigger and smaller sections; each frame can contain different text.
You can also use the <FRAMESET command, which is a replacement for the regular body command.>

Example:

<H1> - <H6> - Tells the browser how big you want the text <H1> being the biggest and <H6> being the smallest. Note: Because Computer Hope is using CSS elements for the H1 tag not only will this text be big but it will have an underline in this example. Without the CSS it would just be big.

Example:

<H1>This text would be BIG.</H1>

Example:

<H6>This text needs spectacles to read.</H6>

Preview:

This text would be BIG.

Preview:

This text needs spectacles to read.
