Allows embedded content inside an <iframe> tag that will respond to theme breakpoints.
Once installed, the component can be used to embed content within a course that will respond to the theme breakpoints - small, medium and large.
Width and height can be specified for the content at each of these breakpoints.
Width and height for each breakpoint is set via the _width and _height attributes. Each of these contain _small, _medium and _large attributes, which correspond to the breakpoint you wish to target.
