Please excuse the messiness of this, I’m clearly in the beginning stages (which is why there’s no CSS code yet)! Can anyone explain to me why my text ‘Things that could be improved in the future’ isn’t showing up but all of the check-boxes etc. are??
Okay… There are some fatal mistakes 
First, remember how the tags are nested.
<div><p></p></div>
not
<div><p></div></p>
Correct your code and see if the problem persists.
Hello, as Walker has already pointed out: you should check your HTML tags. Make sure you close all the open ones.
I hope this helps. Good luck with the project.
