PageSpeed Largest content painful is the main css


We are trying to reach a better number on mobile and we have seen that the only important thing left is the largest content painful which is the main css created by webflow is taking too much time.

How can we improve that?
Are there any way to delay some parts of the css or split it in multiple to handle only one part at the beginning and then the other?

thank you!!
