Video Text Wrap
When a video doesn't need to be displayed at full width, it's usefull to be able to display it on wider screens with a heading and descriptive text to one side of it. The video will become full width on mobile devices and the text will then slide down below it.
The point at which this takes place is the "Break Point". This can be set for iPad in landscape (1059), iPad in portrait mode (799), iPhone in landscape (739) or iPhone in portrait mode (599).
Media files like audio, video and images need a text description if they are to be indexed by the search engines. Combining the text and the video in the same HTML5 container means that the search engines will know that the text relates to the video.
