Heya Stella, you are off to a great start here! I like your code comment
<!--uhhhhhhhh--> lol sounds exaclty like something I would write as a comment too
Something I notice is that you are using bootstrap, but not using the part that will make that portfolio section look way better, and make yoru whole site responsive so that it will also look good on mobile. Heres a link to check out how its done https://getbootstrap.com/css/#grid
Hope that helps…!
