Bulk formatting changes on ASPX files

[sircoolcat]

Hey all, 

So I manually migrated our Knowledge Base to Sharepoint Modern Comms site, however, now I've been told to remove the 'highlight colour' formatting which was copied / pasted from the old system. 

There's about 300 pages! Anyone know if it's possible to bulk update formatting on various pages? Perhaps a script or setting? 

Thanks for your time!

@sircoolcat I don't know of any way to do that except page-by-page. I think your bosses are having a laugh!
