I can't figure out how to put a grey bock around "Get Started"
In order to have a grey block around get started you have to:
1) specify in HTML sheet that you want to edit "btn-main". Your code should look something like this:
By having [a class="btn-main"] it links that class with the class your going to make in CSS
2) Move over to style.css and look for the section .btn-main that codecademy had previously put for you and change the background color according to how the instructions want. The dark grey color I used was #606060.
After that click 'Save' and reload the browser to get an updated version of the website and a grey box with 'Get Started' should have popped up in the middle of your screen!
