I would like to know how to get rid of CSS variables in a production build. The fact is that I need to build a project for IE11 in which CSS variables are not supported. My project was created using React Create App and I can't do npm run eject. How can you set up a production build so that in the initial heart rate of the style, instead of variables, there would be their values?
Don't offer css-vars-ponyfill
, it takes a very long time to load a page in IE11.
