Learn HTML Forms by Building a Registration Form - Step 52

Hey guys, I’ve kinda lost my touch a little, some assistance here. This is my code so far…

input[type="submit"], [display="block"], [width=60%]

And the instruction is " Now, use the attribute selector to style the submit button with a display of block , and a width of 60% ."

nvm, I figured it out
