Web standards are rules and regulations put forwards by the World Wide Web Consortium (W3C.) They are enforced to help develop consistency in design, specifically in the way websites are coded and viewed in a user’s display window.
Websites can be viewed in many different formats and on many different devices.
Promote the use of the specific design code (CSS) which is attached to the website. The use of CSS reduces the size of the web page meaning faster access and lower costs.
Design such as colour and font can be easily changed through CSS- reduces cost of modifying the site.
Search engines can access web pages efficiently.
