Crashing when editing CSS file

I am trying to edit the code so that i can center two of the buttons on the home page. every time i try to edit the bootstrap.min.css file, my browser crashes. Is anyone else having this issue? Please Help!

hi there

Hope you are having a good day and thank you for your question :slight_smile:
You should not edit any CSS file in the theme, instead of this just add new CSS rule in the appearance > customize > additional CSS, this is the proper way of changing style of the element

Thanks!
