When dealing with a platform, such as Hubzilla, that always has a theme active, it can be difficult to find code you can drop in that does not conflict with that theme's CSS.
I finally found an HTML and CSS Library that does not conflict with Bootstrap or Hubzilla themes.
CodeStitch -
https://codestitch.appTheir code snippets use their own CSS & class names that are unique and don't conflict. It makes it easier to build stuff without debugging CSS conflicts or writing everything from scratch.
P.S.
I don't make any money recommending this. This is just a library that I like and use.
