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, large and xlarge.
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, _large and _xlarge attributes, which correspond to the breakpoint you wish to target.
