Hello @Mary-KathleenYo ...
I'm not exactly sure what you mean by "tile view" / "Tile cover". Are you asking how to make your course "Home" page look similar to how course cards are displayed on your Canvas Dashboard?
How do I use the Dashboard as an instructor?
If so, I know that several instructors like to try and create a table on their "Home" page containing icons where students can click on those to navigate to certain areas or modules within their course. The difficulty with tables is that they are sometimes not very accessible, and generally speaking, tables are used to hold data...not as much for design layout...though it can be done. I know there is also a blog entry here in the Community by @clong called Home Sweet Homepages without Tables that might be of interest to you.
I'm not 100% sure this is what you are asking about, so if any of this helps...awesome! If not, please come back to this topic to provide some more details about your request. Thanks!
