Are there online editors of ready-made sites?

Question

WYSIWYG

I have a ready-made website for an online store. It is located on the computer's hard drive. You need to delete and / or replace some things (blocks, change language, change sprites, etc.), but rummaging through the code and deleting manually is too long and dangerous, because, you know, if you start editing html, you will have to css and js, etc... Is there an online editor or a program similar to a site builder, so that the code changes when moving, deleting elements? Please forgive me for my incompetence.
