The FCC test script is still in your survey form.
In the JS editor click the cog icon. You’ll see the CDN is in there.
On a side note, the test script with all tests passing should be included when you submit your projects.
if you want to comment it out for the screen shot than get the screenshot and host that image somewhere. (you can search for sites that host images for free or, if you’re familiar with it, host them on GitHub)
The test script should be right before the closing body tag, not in the head element. Codepen is forgiving that’s why it works but if you were to run it locally you wouldn’t see the test script function properly because the body must be loaded for the test script to work.
I’m attaching a screenshot of your tech doc page full screen. As you can see the body is well below the nav rather than being beside it.
You asked for feedback on your portfolio page. Some things to revisit;
Codepen provides the boilerplate for you. It only expects the code you’d put within the body element in the HTML editor. (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.
