If you build a responsive theme it is important that you know how to make YouTube embeds responsive in WordPress. There are a lot of solutions out there for this but most of them use a plugin that either makes you enter your videos through a shortcode or wraps all of your Iframes in a responsive wrapper. How about we take a little time to build it into our theme so that we aren’t cluttering our site up with more plugins. It is actually really simply!
So you have built a beautifully responsive WordPress theme that works on all devices. Then you or your client adds a YouTube video into their content…ya know for better SEO…and it shoots out the right side of the screen! Now it looks completely broken. You, as a detail oriented web developer, want to make sure that any YouTube video will be responsive inside your theme. But you also know the importance of keeping your site as lightweight as possible so we don’t want to just go add ANOTHER plugin.
