Per the challenge instructions, we need to create a pair of radio buttons. It gives the following example of how to make a radio button:
<label for="indoor">
<input id="indoor" type="radio" name="indoor-outdoor">Indoor
</label>
We need to make one for indoor, and one for outdoor. The radio buttons are inputs, so they need to go inside of the <form> tag. When the submit button gets clicked, all of the <input> tag contents get sent to /submit-cat-photo.
I’d start by making the <label> tags for the indoor and outdoor options and put them in the <form> tag right before the first <input> tag. When you have the <label> for input and output, then put the <input> tags inside of them.
