CSS Validation
Where a website uses valid CSS, its visual display is more consistent in different devices.
What is CSS Validation?
Most modern websites are styled using CSS. This is a language that informs text where to appear and how to look. By writing CSS correctly and free from errors, more screens can display the website clearly. Check your own CSS by visiting http://jigsaw.w3.org/css-validator/.
What are the benefits of being validated?
- More visual consistency. If the CSS contains errors, browsers may not display things correctly and if this affects the primary navigation system people may not be able to get around your website.
- Better performance. Errors need fixing by user agents trying to understand them. If there are less or better still no errors, the user agents such as web browsers can access the data they need more efficiently.
- Lower maintenance. If somebody else is commissioned to update the website, by sticking with the standards and ensuring there are no errors, other designers/developers can get started much more quickly.
