I used to use stuff like Bootstrap and other CSS libraries, but I noticed that there were a lot of stuff that actually wasn't used, but negatively contributed on file size and loading speeds.
Check out this video from Gary Simon at Design Course. This video goes more in-depth on this particular topic, and is one of my sources for inspiration.
Due to these reasons, I decided to create a frontend CSS framework that was focused on customisability and speed, and removing stuff that won't be used.
After a lot of abstract thoughts, I created FluidCSS.
FluidCSS is designed to be easy to customize, and has all the basic stuff you will need, but you must code everything else yourself.
For example, there is a class to create a toggle switch, but there is no grid layout system.
This drastically changes everything.
For one, the file size is a lot less.
Also, beginner developers will not be overwhelmed by the CSS and it will encourage them to tweak the styles.
It will also help more experienced developers to rapidly prototype their designs without worrying about re-creating the same old components or adding a new color scheme.
Be sure to share your opinions in the comments secton!
PS: I really need contributors to this project URGENTLY!!!
Everyone is commenting about PurgeCSS. I actually meant to make something that can easily be customized, but provides enough components, like toggle switches, so that the developer can focus on more client-specific things like layouts and save time, but not end up with a generic bootstrapped website.
