To simplify work, I will upload a page source code by a request. Please ask here for a page you want to fix, and I will attach the html file. You can open it with some editor (Notepad++ has a syntax highlight) and go through it fixing the language. But please don't break the html tags. You may check the code on this site: copy/paste html code to the corresponding window, and this code to CSS:

If you will see broken formatting or a large coloured blocks, them you seems broke something. Note that this site CMS uses some pseudocode on pages, which looks like this: [vc_column][no_accordion active_tab="1"], don't break this too.
Also, to simplify/speedup the work, you may cooperate with other users. Split the file to several parts and fix them separately.
Because the forum is large now, and I have no time to read through all threads, I may not respond during weeks. But if you refer my name in your post (press on my nickname and choose 'Refer by username'), I will be notified by the forum what someone need my attention (the bell icon on the top of the page).
