Web standards…A user centred approach

• Text should be independent of its presentation• It’s inherently more adaptable to other devices (eg: mobiles) and

more malleable to the specific needs of particular users• It’s also easier to redesign: just change the stylesheet

• Your site should not be reliant upon JavaScript• Around 1 in 20 people turn JavaScript off

• Your site will work on all modern web browsers• (Internet Explorer dominates but 1 in 10 users don’t use it)

• Web standards are the future of the semantic web• The process of making content more meaningful to both people

and machines

Web standards are…Consistent with good accessibility

• Search engines can properly evaluate your content• And may attribute more value to it than they would otherwise

• Your web site will be DDA compliant• A legal obligation but particularly important if you have public

sector customers/clients• Your pages will be leaner and load quicker

• If your site has really high volumes of users, this can lower your hosting costs

• Your site can be delivered to mobiles more easily
