Fall Back to the Cascade
When we think of responsive design, we typically focus on newfangled mobile devices like smartphones and tablets. But, as front-end developers, we still need to account for older browsers that can’t handle the newest CSS3 techniques when rendering our sites. In the case of responsive design, that means our old friend Internet Explorer 8 (and below) needs some extra handholding when we build our sites with media queries. These browsers don’t support media queries, and since they are still in widespread enough use that we can’t ignore them (~10% of users are still using IE8), we have to come up with new techniques for gracefully degrading our sites.
