Challenge: Learn HTML by Building a Cat Photo App - Step 60

Link to the challenge:

the attributes can be placed anywhere in the opening tag of an element, same for checked.

You had to add the checked attribute in two elements, the first checkbox and the first radio button.
You added it to the first checkbox, awesome.
Now you need to add it to the first radio button too.

Hi,
Thank you. Finally over it.
