A question—as developers, hands up if you have not heard of Bootstrap? Good—not too many hands going down

Why have I asked this question, I hear you say? Easy—it's to illustrate that in popular frameworks (such as Bootstrap), it is easy to add basic responsive capabilities to media, such as images or video. The exact process may differ from framework to framework, but the result is likely to be very similar. To see what I mean, let's take a look at using Bootstrap for our second demo, where we'll see just how easy it is to add images and video to our Bootstrap-enabled site.
