Is your feature request related to a problem? Please describe.
It's pretty hard to find the description of an abbreviation while reading a webpage but HTML has a tag that shows the description of an abbreviation when the mouse hovers above it.

Describe the solution you'd like
When we hover the mouse above an abbreviation we get a tiny pop-up that shows the description.
