Using CSS Media Queries, you can build a website that remains legible on a variety of viewports and device orientations. However, it’s critical that you let mobile browsers know your content is mobile-optimized. Otherwise, the browser will still zoom out, and your content will be difficult to read and interact with. Luckily, preventing mobile browsers from zooming out automatically is pretty simple. We’re going to add a meta viewport declaration to the head of every page of our website that’s mobile optimized.
