This extension works, though for me it duplicated, triplicated and quadruplicated many lines of css (dozens). It also isn't anywhere near perfect, many @media rules were not terminated correctly or at all, indentation was often out of whack (this may be attributed to the actual css of the page I ran it on but how does one tell?). There was a lot of editing to do after running the extension but it saved me so much time and effort and I definitely do recommend using it when there is no other method available. The version I used was last updated September 9, 2024. I thank the developer/s and hope to see it updated with perhaps the ability to customize how it formats the output.
Insanely good. I was trying to convert a wordpress site to a headless approach with react. I could use rest api for the text but was thinking what to do about styles. Then boom i found this extension. It actually gave me 5000 lines of CSS from elementor. Thanks a lot
