How to include styles through the browser?

Question

css

Tell me, is it possible to connect styles through the browser?
The task is to fix the layout on the site, but there is no direct access to the site files.

Answer 1

Install the browser extension and style any sites, here on chrome

Answer 2

no way. to fix anything, you need files and overwrite access for them.
using jquery like this:

$('body').append('<link rel="stylesheet" type="text/css" href="{url}">');

Answer 3

If it’s for editing, then I advise this livestyle.io - Emmet LiveStyle.

Answer 4

If only for you, then in general you can save your page and styles to your local machine and edit as much as you like.
