Welcome to the forums @craigferguson23. Your page looks good. Some things to revisit;
Codepen provides the boilerplate for you. It only expects the code you’d put within the body element in HTML. (No need to include the body tags). For anything you want to add to the <head> element click on the ‘Settings’ button, then HTML and add it into the ‘Stuff for <head>’ box.
The link to the font goes in the box labeled ‘Stuff for <head>’
There are HTML coding errors you should be aware of and address.
Since copy/paste from codepen you can ignore the first warning and first two errors.
Check that the user has entered a valid email addr when the submit button is pressed. Throw an error if not.
You learned to do this when you made the survey form
Your page needs to be responsive. Things fall out of the container on smaller screens. Grab the right edge of your browser window and reduce the width to see what I mean.
Remember the R in RWD stands for Responsive
One thing to help with responsiveness it to use percentages for widths rather than hardcoding pixel values.
