I'm working on SP 2013 On Premise, In my site i am using a custom css file (reference for which is provided in the master page). In some pages we are using Excel access Web part. I noticed using Chrome developer tool that if a page has this web part then all the css files (including custom css) are loaded first and then at last there is a file called EwrNov.css which is loaded.
Now this causes the existing css to change in the page and the page layout appears to be very clunky. Any Idea how I can unload this EWrNov.css altogether so that the custom styling will get reflected without any issue.
In developer tool I noticed that this css file is initiated by a JS file called EWaMoss.js
Any help would be appreciated, I'm stuck trying to load my css file again, after this EwaMoss.js gets loaded, from masterpage
