This article will help you master your browser’s DevTools, so you can edit websites, tweets and more
Inspect Element
this is an essential tool for editing websites
How To Open
use CMD + SHIFT + C on macOS or CTRL + SHIFT + C on Windows or Linux
alternatively, you can right-click and press Inspect

The Dev Tools Menu
The menu is split up into many tabs:
Inspector and Console are the main ones we will be using
Inspector lets you view the HTML of a page and edit the changes live
Console allows you to view logs and use JavaScript commands
note:this may look slightly different on other browsers, but the functionality will be the same
Using Inspect
I will be using example.com for this example, but this will work on any website or HTML document
- Step 1
open the dev tools - Step 2
I would recommend making sure that this icon is highlighted

this icon allows you to hover over an element and then click on it to jump to it in the inspect menu

Document Design mode

open the
Consoletab

- step 2
typedocument.designMode = "on"and press enter
this enables document design mode, you can now start editing a page by simply clicking text, you can also delete elements by selecting them
