1. Structural HTML

Most developers pay attention to the graphical presentation and often neglect the structure of document. An HTML document marked up structurally can adapt to different environments. Hence, an HTML document must be structured in such a way that it can be read without stylesheet.

2. Anchors and Links

Links are what made the web The Web. One should provide meaningful links and should make sure that links are accessible in text based browsers as well.


<a title="My Page" href="mypage.html">My Page</a>

3. Alternative text for non-textual data

To provide text alternative for non-text data like images you can use ALT attribute for briefly describing meaning. You can also make use of LONGDESC attribute for long descriptions.


<img longdesc="long desc" src="banner.gif" alt="Alt Text" />

Similarly, one should be careful using Image links. Without text equivalent, screen readers will not be able to display the link. Son Use of ALT attribute can allow screen readers to access link text.

4. Tables

Following tips should be kept in mind when using tables for layout:

  1. The WIDTH attribute on TABLE, TD, or TH elements is usually unnecessary and can hinder a document’s accessibility. So, one should control all attributes using CSS.
  2. Row and column headers should be distinctly visible. For column headers, TH is preferred rather than TD. Providing CAPTION or TITLE to describe the contents of table makes more meaningful.

5. Client Side Scripting

Client Side Scripting like JavaScript is not supported by all browsers and sometimes users can disable it. Hence one should make sure that web page is usable even scripts are not supported or turned off.
One should not rely on Client side scripting to navigate or view content. When JavaScript is used, it should not be relied upon.

6. Colors

Some old browsers do not support color names. Colors should always be specified with a hexadecimal triplet in the form #rrggbb or #RRGGBB. We should make sure that information presented through the use of color is available without it.


   color: #000000;
   background: #ffffff;

7. Text-based browsers

Simulate the web page on text-based browser such as Lynx to see how document would look like in absence of graphics.

8. Validation

Validation of HTML documents is most important part. A validator checks the document’s HTML against a document type definition to ensure that the syntax of the HTML is correct. Validate your document to check for errors.
