Course blocks are small blocks of information about specific courses that appear on All Courses and Your courses index pages. The information displayed in a course block and its visual structure varies slightly, depending on where it appears.
Course block on Courses page
On the Courses page the blocks display key information about the course, such as description, duration, hours per week required, and availability of certificates.
Course block on Your courses page
On Your courses page, once the course has started, the information about the course is replaced with a more specific actionable info, such as course progress/timeline, and other actions related to the course.
