What does the F12 key do?
- In web browsers, the F12 key typically opens the Developer Tools. This powerful feature allows developers to inspect and debug HTML, CSS, and JavaScript, monitor network activity, and analyze page performance.
How Do I Remember It?
- F12 is like x-ray vision for websites. Just as Superman uses his x-ray vision to see through walls, developers use F12 to see through the layers of a website.
Real World Example
- A web developer notices a button is misaligned on a webpage. By pressing F12, they can inspect the button's HTML and CSS, make adjustments in real-time, and see the changes immediately.
