Could you explain me why you set some css rules in cs.theme.7.6.0 with !important?
It breaks a layout of my first section on one of my websites that needs margin-top: with negative values! Now i couldn’t overwrite it with custom css in the editor as it worked before upgrade to 6.6.0.
There are many more css settings that have an !important attached!
I used integrity stack before, and even with switch to starter pack didn’t help.
