Thank you for your feedback! I actually didn’t know to center my elements, but I will implement it into my code once I get to redoing it and take it into account for future codes.
I’m actually working on the product landing page right now and looking into flex and grid to see which one is best going to work for what I have in mind. Also working on a dropdown nav, which is going to take me some time to get through what i’ll need to do for that, since that also involves the pseudo classes you mentioned. We’ll see how that goes!
EDIT: I wanted to add I wasn’t feeling particularly inspired with this project, so I agree it is very basic. I tried a couple of things design wise, but I honestly liked the simple design better. A form like this doesn’t need bedazzling, so I gave up on that for this particular project. My first project has more features than this one (linear-gradient borders and flex are examples).
