What makes this css?

Now the ease of the website conducting activities on cleaning of all the excess came across a css file at:

It weighs 500KB(!), but it is not a file of the theme and any plugin without it too, layout go.
What it is and how to get rid of it?

Times without this file everything breaks, is one way to remove all unused and optimize the remaining (output "cut all used in separate file" is functionally identical).
To do this, here's a useful link:
How to remove unused styles from the CSS file?

But there is one "but" - according to the name of the file, it is generated automatically and may be about several others. Then you need to search for the mechanism of Assembly and to avoid what is really not being used. If you do not want it, you can just copy the file to the new location, plug it with your hands and do all operation on optimization that I described earlier.

It's just some CSS library, written backgrounds, etc.
It is taken from the theme?
I just annoying that it weighs under polumegabayta. It is on that theme styles weigh polyhabit - zoila.Hartmann28 commented on July 12th 19 at 16:45
: customer shakes 50KB, the file is gzip compressed. - parker commented on July 12th 19 at 16:48
: most likely Yes. Try to see everything that goes (buttons, grid, etc.) and easy to fix, and then disable the file - Daniella_Koepp commented on July 12th 19 at 16:51

It's just embedded in CSS images. The purest example of an anti-pattern as picture, obviously, on all occasions, and the file weighs disproportionately much.

Also due to the lack of modern methodology selectors weigh too much. Most likely due to impurities and such things in the preprocessor. Usually if it is said that "gzip still compresses". The result can see for yourself.
