How to Validate CSS Pages

So you've learned CSS and created style sheets to replace bulky HTML code. Something's not quite right and you want to make sure you're putting everything in the right place. You can check your CSS code using a free, easy Internet application.

Difficulty: Moderately Challenging

Instructions

Things You'll Need:

• Web page design files that you've written

1. Collect the urls of the pages you have designed.

2. Locate the website of the W3C on the Internet. The W3C is an organization set up to help designers with universal design standards for the web.

3. Click on the link for the 'CSS Validator' located on the left side of the home page.

4. Put one of your urls into the text box on the Validator page.

5. Hit the 'Check' button.

6. Record any errors on the page that appears and look at the code modules the validator referenced.

Tips & Warnings

• Make sure your url has CSS content to check. It can be difficult to separate CSS from other design elements, but the code can be put in a specific place, or even in separate files for better access.
• Don't enter more than one url at a time.
• If you need more information on types of errors, find explanations on the site or look for a good CSS book.
