Introduction: The F12 Button

Picture of The F12 Button

Hey... this is my first instructable (YAY) so stick with me:)

The F12 button is a powerful button on the computer.  You can change the website name, the color, where everything is, and all that good stuff.  

P.S. I've spent many hours messing around with this... It's entertaining

There is also so much more... but have fun with this for now :)

Step 1: Basics

Picture of Basics

So you open up the website you want to temporarily change and hit "F12"
Once doing so, there will be a list of stuff on the "Developer Tools"
This is what you will use to change around the website.  

Step 2: Changing the Title

Picture of Changing the Title

I am using Google for this... but it works for any site.
So open Google, and hit F12
There you will see a section labeled "<Head>
click it, and under it there is <title>Enter what you want here<title>
and... you get a personal title :)

Step 3: Web, Images, Etc...

Picture of Web, Images, Etc...

On Google, at the top there are labels (We, Images, etc...)
Using F12, you can change the size.
When your at the developer tools, go to <Head>, <Style>, and type in any number

You might want to mention wich browser.. Firefox 8 this does not appear to work, but it does under Chrome.

Though it kind of works if the Add-On Firebug is installed. Anyway, it is not good style to assume that what works on your computer will work the same way on any other machine.

it won't work on a mac either because the f12 button changes the volume

If you really like taking things apart and want a permanent change on your websites, you should try some browser extensions like Greasemonkey or Stylebot. With some basic skills, you can change websites up to look just about however you like. If you really like it, you can share your work on the web. 

Good job though. I think this is how I first started goofing around. 

swooshhair (author)jquiring2014-11-12

Does it stay permanent, until the website dev.'s fix it, for ex. my school website got hacked and was left with a blank white page that said "nope". Not that this would be my goal I am just curious, thanks.

bakedicecream (author)jquiring2011-11-16

lol thanks I'll give it a try!

swooshhair (author)2014-11-12

Is there anyway to make it permanent...or is that legit hacking? I'd really like to know, otherwise, why else would the button be there; I mean, sure, it's fun to play around with but what's it real purpose?
