Use Your Browser to Edit Any Live Web Page Using a Single Line of JavaScript
An easy JavaScript technique for making any website editable. After checking it out for myself, I just had to share it. Here it is:
javascript:document.body.contentEditable='true'; document.designMode='on'; void 0
Paste that single line of code into the address bar of any modern browser and have fun editing the page. Obviously, any changes will only apply to the page as seen in your browser, not the original document. Even so, it’s a fun trick to play around with, snap screenshots, be creative, etc.
For easy access you can also bookmark it!
