How to pin changes in the Opera inspector?

Question

Browsers

Good afternoon. So. Let's say I changed the div class in the opera inspector, but after reloading the page everything falls into place. Is it possible to fix the changes so that they do not disappear after a reboot? For example, I redesigned vk.com in the inspector to suit my needs and want to keep it that way. Plugin, setting, mb something else?

Answer 1
