How to remove all CSS from a page at once

New Course Coming Soon:

Get Really Good at Git

I wanted to see how a page looked like without CSS.

One way I know is to open the DevTools, in the Sources panel you’ll see the list of CSS files. You can remove the content in the CSS file in there, and the page will change. For example here’s my <thereactcourse.com> site.

It has 3 CSS files, and I can go and delete the whole content of one:

and this is what happens, the page changes because we removed the CSS:

Note that this just changes the browser’s version of the CSS, does not interact in any way with your file, even if it’s local

But some sites today embed the CSS in a style tag (including mine), and some have loads of CSS files scattered around, and it’s not practical.

Open the console and run this command:

document
  .querySelectorAll('style,link[rel="stylesheet"]')
  .forEach((item) => item.remove())

This removes both inline and linked CSS.

Are you intimidated by Git? Can’t figure out merge vs rebase? Are you afraid of screwing up something any time you have to do something in Git? Do you rely on ChatGPT or random people’s answer on StackOverflow to fix your problems? Your coworkers are tired of explaining Git to you all the time? Git is something we all need to use, but few of us really master it. I created this course to improve your Git (and GitHub) knowledge at a radical level. A course that helps you feel less frustrated with Git. Launching May 21, 2024. Join the waiting list!
