CSS Validation
CSS validation checks the code against the formal guidelines and standards set by the World Wide Web Consortium (W3C) for CSS documents.
Why Validate Your CSS Code
You may make mistakes as a beginner while writing your CSS code. The non-standard or incorrect coding may cause unexpected results in how your page functions or is displayed in a web browser.
The tool created by the World Wide Web Consortium (W3C) https://jigsaw.w3.org/css-validator/ lets you automatically check your style sheets. It also points out any problems/errors the code might have, such as invalid CSS property, missing closing bracket, or missing semicolon (;) etc. This tool is absolutely free.
Validating a Website
Website validation is the process of making sure that a website's pages conform to World Wide Web Consortium's (W3C) formal guidelines and standards.
Some of the reasons for validating a website are:
- For creating web pages that are cross-browser, cross-platform compatible. Ensure the website is compatible with the future version of Web browsers and Web standards.
- Web pages that comply with standards increase the search engine's spider visibility, and as a result, the likeliness of your web pages appearing in search results increases.
- It will minimise unexpected errors and ensures web pages are more accessible to website visitors.
Note: Validation is important. Validation ensures your web pages are interpreted in the same manner (the way you want) by the different web browsers, search engines, etc., and by your website's users and visitors.
