This is one of the first sites I mocked up after learning about Flexbox. And that's when I learned two things. ONE: put everything in a div. Then put that into another div. And another div. TWO: Flexbox is your best friend.

I wanted to mock up a shopping site that's clean and modern, so I picked Madewell, a site I visit frequently. I thought it would be easy, putting divs inside divs, but I learned that clean design is harder to execute than you think.
