It’s very simple
1. Open the website you want to hack,
2. Enter in the address bar of the browser:
javascript:document.body.contentEditable='true'; document.designMode='on'; void 0
3. Now you will find that his page can be modified freely by you! !
4. After modifying it according to your own intention, enter in the address bar:
javascript:document.body.contentEditable='false'; void 0
Okay, take a screenshot and "hack" the other party's website~~
Hehe, it’s harmless. It can be used to scare people, which is much more convenient than saving HTML
