Webpage editing

[Vexian Empire]

I found a cool thing that lets you edit a webpage.
Step 1: Right click and then click 'Inspect'
Step 1 Alt: Hold 'Ctrl' and 'Shift' and press 'I' (Ctrl+Shift+I)
Step 2: Click 'Console' unless you are already viewing it
Step 3: Type this code in:

Code:

document.body.contentEditable = true

Step 3.5: Press 'Enter'
Step 3.75: All steps after 3.5 are optional
Step 4: Enjoy
Step 5: To undo it, type this code in:

Code:

document.body.contentEditable = false

Step 5 Alt: You can also reload the page
