Currently, I am working with a bootstrap template on my webpage. I am interested in personalizing specific sections of the design, but unfortunately, I am having trouble identifying the relevant CSS rules within the extensive .css file.
My research online has only led me to methods for searching for files rather than searching within them. There might have been an extension that could have helped with this issue, but it appears to no longer be available.
I would greatly appreciate any assistance you could provide on this matter.
