The Content Blocks are used to fill in the promotional content you would want to send via the landing page. The content blocks are divided into three parts with similar layouts:
Content Block A: Content in this block sits above your video, if you have one.
Content Block B: Content in this block is displayed below your video and above your form (if using).
Content Block C: This is the very bottom of the page, any form used will be directly above this content block.
