Interactive Inspect element, condensed in a JavaScript bookmarklet. (Stolen from Mozilla)
Only reason this repository exists is because I found it surprisingly hard to get the code for this. (More accessible for me and possibly you)
1. Go to bookmarklet.js or use this link
2. Press the "Raw" button to view the code on a seperate page.
3. Copy the script on the page.
4. Create a new bookmark titled whaatever you want, and paste the script as the url.
5. Go to a site you would like to edit and click on the bookmark.
Note
Some sites block and affect how bookmarklets work, sometimes causing it to not work.
You are now able to edit the html of anything on the page by clicking it
The rest is self-explanatory, have fun!
