I like https://feathericons.com/

There are less icons then font-awesome, but is all svg and is easy to customize.

Loved the site. The site had a problem with my company monitor, the contrast of the input was too low that I couldn't see.

Hi, some unwanted feedback, I can't see the scroll. Using chrome on ubuntu 18.

My mouse doesn't have a functional scroll wheel, i had to use the trackpad to see the rest of the site.

A lot of people care.

There's back-end developers who doesn't know front, but the pattern and it's docs facilitate to create an easy and fast platform. Not every site need to be unique, some sites are a basic CRUD to manage information to whenever he needs.

And bootstrap has a pretty good example that can teach a lot of developers.

I've used bootstrap a lot, and learn a lot also. New front-end developers can learn a lot with bootstrap.

underscores.me is the one that I recommend.

Clean and easy to customize.
