How do you change background color on "thank you" page?

The best way to do this that would work for all cases is to do the following:

1. Go to your Thank You Page (for editing)

2. Click on the "Source" button

3. Add this code before all other code:

<div style="background-color: orange; position: fixed; height: 100%; width: 100%; top:0; left:0">

4. Add this code after all the other code:

</div>

- This is how it should look after adding the codes

6. Save and test

Here's a demo form where I set the background color as ORANGE.
