All web pages have this basic code:

<!DOCTYPE html>: This tag has been simplified in HTML5 since the multiple <doctype> declarations were eliminated -- leaving just one: html. In HTML 4.01 <doctype> declarations include: strict, transitional, frameset and the XHTML 1.0 declarations of strict, transitional, frameset and XHTML 1.1.

<HTML>: Begins your document

<HEAD>: Contains information about the page such as META tags and title; this is not rendered in the web browser

<TITLE>: Your page title -- visible in the browser tab

</TITLE>: Closes <TITLE> tag

</HEAD>: Closes <HEAD> tag

<BODY>: This is the content area of your web page -- where you will include text, images, graphs, etc.

Everything inside the <body> tag is visible in the browser. At the end of your HTML page, you need to close open tags by using:

</BODY> to close the <BODY> tag and

</HTML> to close the <HTML> tag.

Helpful <html> Snippets

Possibly one of the most commonly used HTML tags is <table>. Most tables use three main tags: one for the container, one for the information inside the table, and one to designate a row inside the table.

HTML Table

To build a table with two rows and two columns you use all three tags. Although you can style from inside the tag, for example, <table border="1">, the preferred method is to control the look with CSS.

< tr>
< td>This is the first box in Row 1</td>
< td> This is the second box in Row 1</td>
< /tr>
< tr>
< td>This is the first box in Row 2</td>
< td> This is the second box in Row 2</td>
< /tr>
< /table>

The same table with a header column that spans both columns would look like this.

<th colspan="2">This row stretches across both rows below it.</th> The <th> -- table header -- bolds and centers the text.
< tr>
< td>This is the first box in Row 1</td>
< td>This is the second box in Row 1</td>
< /tr>
< tr>
< td>This is the first box in Row 2</td>
< td>This is the second box in Row 2</td>
< /tr>

To Do List

By taking advantage of local storage, the latest version of Google Chrome and other browsers, allow you to create a list that can be edited from inside the user's browser. To set it up, you need to associate the attribute contenteditable with the list.

<h2>My editable List</h2>
<ul contenteditable="true">
<li>Go to grocery store </li>
<li>Drop paperwork off at office</li>
<li>Finish errands</li>

When users access the above coding from new browsers (not Internet Explorer), they can edit and change the list as they choose.

How CSS Interacts With HTML

HTML is a markup language and its role is to structure the page. Since the markup language is read top to bottom by the browser, the more important information should be at the top of the page -- and be wrapped inside the appropriate tag.The top headline should always be a tag -- usually a


, paragraphs go inside

, etc. this way the browser (and search engines) can validate the hierarchy of importance for the text on the page.

Because HTML should be used only for the structure of a document, CSS is used for the design and look. Although, some HTML tags can be minimally styled without CSS, the best practice is to control your site's design with CSS. CSS works by creating names for the various types of content on your page. When the browser reads a CSS 'name' -- it applies the style -- associated with that name -- to the content.

Can't Remember All The Tags?

The good thing is you don't need to -- you can use a reference list like this to double-check what a tag is designed for -- or use an HTML editor with a built-in reference like HTML-Kit. What is more important than memorizing all the tags is to design pages with current and future browsers in mind. By doing this, when users catch up and install the most current browser, the new tags will already be in place -- and work as designed.
