I've gone to a lot of effort to design visually appealing homepages for my students that help link them out to different areas in the modules. 

Unfortunately when they view them on their chromebooks the resolution or screen size must be different because items such as buttons don't fit right and things overflow.

I'm frustrated because once again, it seems I need to know html to code a page that is visually appealing AND responsive in size for a variety of devices.

Has anyone run into this and what did you do to help the issue?
