Developer tools on different browsers

Did you know, every modern web browser includes its own set of developer tools?

If you didn't, that's okay. Developer tools aren't always the easiest thing to find in your browser. So, we've decided to help you out by creating this guide to developer tools!

Microsoft Edge

Microsoft Edge introduces great new improvements to the F12 developer tools seen in Internet Explorer. The new tools are built in TypeScript, and are always running, so no reloads are required. In addition, F12 developer tools documentation is now fully available on GitHub.

Just like Internet Explorer, to open developer tools in Microsoft Edge simply press F12.

1. What Is CSS?

If you want to try removing the style from the Youtube homepage yourself, follow these instructions:

  1. Visit https://www.youtube.com/ or any other website of your choice.
  2. Right click anywhere on the page, and click "Inspect" (on Mac) or "Inspect Element" (Firefox)
  3. You'll see a panel showing HTML. Inside the <head> element, delete any line that has rel="stylesheet". For example:
<link rel="stylesheet" href="//s.ytimg.com/yts/cssbin/www-core-webp-vflCayM79.css" name="www-core" class="css-httpssytimgcomytscssbinwwwcorewebpvflCayM79css">

Congrats! You have just used Developer Tools! You will learn more about Dev tools later in this lesson.
