completed with html and css, no javascript

Hey, great job!

One thing I've spotted:

• I'm not quite sure you need position: absolute to position the buttons within each section. With the code as it is, your buttons will always be 50px from the bottom of their container. When I reduce my window size to check responsiveness, the buttons jumped up and overlapped your text. I think the correct spacing could be easily achieved with simple margins.

Hope that helps!
