Here are my thoughts on your tribute page.
You need to keep the test suite in the page.
You are currently only passing 1/10 tests. Please open up the test suite and read the full error message to see what needs fixing in order to pass the tests.
For all of the certification projects, you need to make sure all of the tests are passing before you submit the projects.
For codepen you do not need to include the html and head tags.
The center tag is obsolete. If you want to center items please use css instead.
Please avoid inline styles like this
style="color: white". Place all of your css in the css section.
Please do not use br tags to create space between elements. Use css instead.
Hope that helps!
