A tool to inspect font-family usage in a webpage.
## What's it for?
To have a quick look into font-family usage in a webpage.
Texts inside these elements will be ignored: script, noscript, style, iframe, option.
Invisible elements won't be taken into account as well, which includes those with opacity: 0, display: none and visibility: hidden.
The result will sort all used font-family values by the number of glyphs they apply to. ie. most used one will be at the top of the result list.
