I should mention that I did a study about 6 months ago for a government client, and successfully convinced them to migrate away from Bootstrap 4, Font Awesome, and an in-house patchwork of 10 years of different css styles, to Tailwind CSS and Hero Icons in their mission critical app.

It took many long brain dump sessions, and some help from the U.S. Digital Service and Tailwind themselves.

At the end of the day, Tailwind solved more problems for them than it created.

You wouldn’t think that moving from loading icons via css versus loading them via inline svg’s would make a huge difference; but I found that it can actually reduce a second or two of render time from a legacy and bloated code base.
