What to do with big css file?

Question

css

There is one online store. And css files connected to it - occupy 2-3mb.
In principle, they are already minimized.
The largest css file is 730kb, this is the Visual Composer plugin file. I use it on some pages, and basically don't want to delete it yet.
Question: what can be done to reduce the size of the loaded css?
Or will you still have to remove the plugin and rewrite the site manually?

Answer 1

Is Visual Composer not about the admin part?
Clean up unused CSS.
What is there in general for 2-3mb maybe, this is enough for five sites.
ps
Checked my css.
30 css in one are going to 350kb
This is a whole bootstrap and a bunch of different libs.
