Challenge: Learn HTML Forms by Building a Registration Form - Step 56

Link to the challenge:

you have accidentally deleted the } for the previous code block

The instruction: “Now, use the attribute selector to style the submit button with a display of block, and a width of 60%.”
You should create a new selector, and put into it new properties (display and width) and their values:

input[type="submit"]  {
  property: value;
  property: value;
}
