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
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
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...
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
