Args:
content_array: an array, each of whose members is of type Content. This

following:
- 'text'; then the value is a text string
- 'image'; then the value is an image ID
- 'video'; then the value is a video ID
- 'widget'; then the value is a widget ID
block_number: the number of content blocks preceding this one.

the HTML string representing the array.

'type' attribute.
