Web Quality - Standards

Writing your pages according to web standards helps improve the quality of your website.

HTML standard

XHTML is the latest HTML standard, which is a reexpression of HTML 4.01 using XML.

Writing pages according to HTML 4.01 can make your site as close as possible to the XHTML standard.

CSS Standards

For high-quality sites, using Cascading Style Sheets (CSS) is the preferred method to separate content from style. By using CSS, you can store all the information about page styles in a single document.

All modern web browsers support CSS 1 and CSS 2 standards.

Using CSS can improve the quality of your website and increase readability for different browsers. It can also greatly reduce your website development costs.

Web Validation

Web Validation Tool is a software program that can check your website according to web standards.

After you have checked the HTML, XHTML, or CSS document with a validation tool, the validator will return a series of errors found based on the standard you have chosen. Typically, the validator will return the line numbers of the errors found.

Make sure you validate your pages before publishing them a habit.

WAI coordinates global organizations to enhance the accessibility of the Internet through six main areas of work: technology, guidelines, tools, education, research, and development.

You can improve the quality of your website and make your site accessible to more people (and browsers) by writing pages according to WAI guidelines.
