Writing your pages according to web standards can help improve the quality of your website.
XHTML is the latest HTML standard and is re-expressed with XML HTML 4.01.
Writing pages based on HTML 4.01 brings your site as close to the XHTML standard as possible.

For high-quality sites, using Cascade Style Sheets (CSS) is the preferred way to separate content from styles. By using CSS, you can store all information about page styles in a separate document.
All modern web browsers support CSS 1 and CSS 2 standards.
For different browsers, using CSS can improve the quality and readability of your website. It can also significantly reduce your website development costs.

The web verification tool is a software program that checks your website against web standards.
Once you have checked html, XHTML, or CSS documentation using the validation tool, the validator returns a series of errors based on the criteria of your choice. Typically, the validator returns the line number of the error found.
Make sure you verify that it's a habit before you publish the page.

WAI refers to the Accessible Web Initiative ("Web Accessibility Initiative"), initiated by W3C.
WAI coordinates global organizations to improve Internet availability through six key areas of work: technology, guidelines, tools, education, research, and development.
You can improve the quality of your site by writing pages based on WAI guidelines and make your site available to a possible 30,000 people (and browsers).
You'll learn more about WAI later in this tutorial.
