Hello @danielhaim1, thank you for submitting this PR.
While we don't enforce a linter on the documentation site's CSS, and as such don't have rules in place,
we prefer indenting with just 2 spaces per level instead of 4 spaces or more per level :

• Changed indenting to 2 instead of 4 spaces
• Added font-display feature to FontAwesome

I see a lot of unnecessary changes like changing double-quotes to single-quotes, removal of comments and other whitespace changes.

Please limit the amount of changes to just those that are actually necessary.

@ashmaroli thanks for reviewing again.

I updated docs/_sass/_fonts.scss and improved the comments there. The original comments were removed because they were incorrect. Lato (300) is Lato Light, but stated as lato-300 latin

In other cases, I converted inline CSS comments (/* comment */ to // comment) which are better for scss.

In other changes, I've sorted the CSS properties with each selector declaration in a predefined order to be as close as possible to the browser engine.

You're welcome. Understandably, the amount of changes increases the amount of time for reviewing.

You can help us out by going through the diff and reverting changes to quotes, undoing removal of blank lines at end of file and basically revert all whitespace changes that will keep the diff shorter

@ashmaroli reverting the files back to normal, and only added my most critical changes.
spaces are now back to normal, and the file is no longer sorted by property name.

Let me know if you'd like me to comb the file again, it saves approx ~300 lines.

The most noticeable change from this PR is the rendering of numerals:

Yup! The reverted looks good to me as well.

The reverted looks good

@devMoses Um.. I don't see the revert commit here.
The last preview-build on this branch still shows the numerals rendered with lesser vertical height:
