Are you validating your website's HTML/XHTML and CSS? If not, you should be.

Having HTML/XHTML and CSS code that is compliant with standards is important for the following reasons:

  • It increases the likelihood that visitors using different browsers are still seeing your website as you intended it to be seen.
  • It increases the likelihood that visitors accessing your website using  devices other than a PC will be able to access it successfully. Don't forget that a significant number of people access the internet through portable devices, for instance!
  • It helps those with disabilities access your website. For a larger business in the United States, compliance with ADA standards may be an internal requirement.
  • It can assist with SEO.
  • I have personally found during the process of developing a website that validation usually results in cleaner code that is less bloated, which can help boost load times.
Given these benefits, and the fact that there are a number of online tools that you can use to validate your website's HTML/XHTML and CSS, there is no reason not to validate!

Here are some easy-to-use online tools for doing just that:
