Quick HTML Reference

Reposted on HTML Goodies with permission.

Basic Structure:

<!– ….. –>

Specifies a comment. Anything between these tags will be skipped by the browser.
<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 3.2 //EN”>

This is the necessary first element of any HTML 3.2 compliant document.
<HTML>…..< /HTML>

Encloses the entire document.
<HEAD>…..< /HEAD>

Encloses the head of the document. The following optional tags are placed inside the head.
1. <TITLE>…..< /TITLE>
  
  Indicates the title of the document that is used as the window caption.
  This is the second of the two required tags for any HTML 3.2 compliant document.
2. <BASE href=”http://some.network/file.html”>
  
  Specifies the base URL of the document. This is used when dereferencing relative URLs in the page.
3. <BASE href=”http://some.net/file.html” TARGET=”…”>
  
  Also specifies the base target frame that all links will default to. See the LINK tag for possible values used in TARGET.
4. <META attribut1 attribute2>
  
  This element can be used to specify name/value pairs describing various properties of the document. Below are some examples:
  
  To have your page automatically reloaded every X seconds, use the following:
  
  <META HTTP-EQUIV=”REFRESH” CONTENT=X >
  
  To have a different page automatically loaded after X seconds, use the following:
  
  <META HTTP-EQUIV=”REFRESH” CONTENT=”X; URL=http://some.address/file.html”>
  
  To specify an expiration date for the page so that it will be reloaded after a certain date, use:
  
  <META HTTP-EQUIV=”Expires” CONTENT=”Mon, 23 Sep 1996 01:21:00 GMT”>
  
  To specify keywords for certain search services to use, do the following:
  
  <META HTTP-EQUIV=”Keywords” CONTENT=”keyword1, keyword2, …”>
  
  To specify a description of your page for certain search services to use, do the following:
  
  <META HTTP-EQUIV=”Description” CONTENT=”Describe your site here….”>
5. <LINK attribute=” HREF=”…” >

  tags to generate a navigation bar for the site. Without browser support, this tag can still
  be useful for site maintenance.

style definitions (explained below) in that file. Then, using the LINK tag, you can
link the style definitions to your current document.

Using this method, you can have one style sheet for the entire site that is linked to
each page. That way you can alter the look of all your documents be simply editing the
.css file. See syntax below.

Inside the HEAD tag, add something like this:

<LINK REL=STYLESHEET HREF=”URL of style sheet” TYPE=”text/css” >

Your Style Sheet might contain something like this:

H1 {font-size: 20pt; font-weight: bold}

H2 {font-size: 16pt; font-weight: bold}

P {margin-left: -20px; margin-right: -20px; margin-top: 30px}

BODY {background: URL(http://my.server.com/pictures/back.gif); text-indent: 2cm}
Adding a Style Block

To set the style for an entire page, you can place all the style definitions (explained below) inside
the <STYLE>…..< /STYLE> tag. This tag goes inside
the HEAD of your document. Make sure to enclose the definitions within comment tags
so that older browsers do not display them. See example below.

<HEAD>

.

.

<STYLE TYPE=”text/css” >

<!–

BODY {font-family: Arial; font-size: 12pt; font-style: italic}

P {margin-left: 30px; margin-right: 30px; margin-top: 10px}

–>

< /STYLE>

< /HEAD>
Inline Style Attributes

If you simply want to change the style of a particular section of your document, you can
do so with the STYLE attribute. You can place this new attribute inside just about any HTML
tag, and the style definitions will be in effect until the closing of that tag.
Below are some examples.

To change the color and indent of a certain paragraph, you could do the following:

<P STYLE=”margin-left: 1in; margin-right: 1in; color: #0000FF”>

This text would be indented and blue.

< /P>

To change the style for an entire portion of your document, you might do the following:

<DIV STYLE=”margin-left: 0.5in; margin-right: 0.5in; font-family: Arial”>

This whole division of the page will be indented and any text will be displayed in the Arial font.

< /DIV>
Style Definitions

All three methods of adding style to a document use the same syntax for style definitions.
Except for inline attributes, a style definition consists of a tag followed by a list of
specifications enclosed in curly braces. You can define styles for any tag in HTML. Once
you have specified styles for a certain tag, every time the tag is used, the styling will be in effect.
Below is a list of all the style definitions and their possible values.
1. background –&nbspSpecifies a background color or image.
  - Values: URL|RGB triplet
  - Example: BODY {background: #FFFFFF}
2. color –&nbspSpecifies the color of the text.
  - Values: RGB triplet
  - Example: H4 {color: #000000}
3. font-family –&nbspSpecifies the typeface.
  - Values: typeface name or list of names
  - Example: P {font-family: Arial, Helvetica, “Courier New”}
4. font-size –&nbspSpecifies the size of the text.
  - Values: pt (points)|in (inches)|cm (centimeters)|px (pixels)|% (percentage)
  - Example: A:visited {font-size: 14pt}

  - Values: pt (points)|in (inches)|cm (centimeters)|px (pixels)|% (percentage)
  - Example: DIV {line-height: 20pt}
8. margin-left –&nbspSpecifies the left margin.

Additional Options
1. Grouping
  
  Certain style definitions can be grouped together in one statement. Instead of using
  three statements to specify all three margins, you could use the following:
  
  P {margin: 20px 3cm 3cm}
  
  The order is top, right, and left.
  
  You can also group all the font statements together like this:
  
  A:active {font: bold italic 15pt/22pt Arial, serif}
  
  The weight and style must be specified first, and the first number represents the size,
  while the second number represents the line height.
2. Classes
  
  You can also define more than one instance of a tag. For example, say you wanted two
  H1 headings; one that was red and one that was blue. You could define the two tags
  like this:
  
  H1.redh {color: #FF0000; font-size: 20pt}
  
  H1.blueh{color: #0000FF; font-size:20pt}
  
  Later you could use them like this:
  
  <H1 CLASS=redh>This will be red< /H1>
  
  <H1 CLASS=blueh>This will be blue< /H1>
