Display Content Clearly on the Page

3.12 Make websites responsive.

Today’s users expect websites to work well on every screen they touch—whether it’s a phone, a tablet, a desktop computer, or whatever else we haven’t thought of yet. More and more, users are accessing the web from mobile devices. And for some—especially low-literacy users—mobile devices may be their only means of web access.17

A main advantage of responsive design is that a single website can deliver content optimized to appear on a wide variety of devices and screen sizes. But keep in mind that responsive design is limited in that only format—not content—can be tailored based on a user’s device. That’s why it’s so important to develop content for the smallest screen size. By doing so, content developers must make tough choices and create a thoughtful, logical content hierarchy and cut (or link to) superfluous information.

Most of the time, users won’t think about how your site was built—they just want a seamless experience across devices.72
