Button links in Personal Portfolio Beginning project (please save me from my mounting rage)

I have no idea what the problem is here. Two of these button links that I’ve created are working just fine, but the others won’t work. yet, the addresses in them are correct. I have no idea what the problem is. Please help!! (ps some weird rule only allows me to put 2 links in a time so I can only post 2. There are 5 in my actual page.

I am quite new to coding. Perhaps nesting your a tags within your button tags will do the trick.

Can you share a link to your Codepen of this project?

Thanks so much for the help everyone. I was able to solve the problem.

I’m new at this, don’t judge me!

Ha, seriously, if you do happen to look and have any feedback, I’d appreciate it. Still learning this stuff.
