Hi @HeideeVincent ...
Instead of trying to make things look the way you want with HTML code, what about creating a simple image that you can just re-use over and over again in your course as you see fit? For example, I created this image in about 2 minutes using the Paint program on my Windows laptop:

Then, I can just create a link on this image to wherever I want in my course (being sure to also add "Alt" text for screen readers, of course). This gives you a bit more creativity in creating a cool looking button for your course...using color, shapes, etc.
How do I create hyperlinks to course or group cont... - Instructure Community (canvaslms.com) -- use the procedure in this Guide to create links on images, too.
The suggestion from @StephenBryant01 may be ok, but tables are not as accessible and are typically used to hold data. So, you might want to consider something other than that.
Just a thought...for what it's worth. Hope to hear back from you soon.
