My first attempts with css grid

hey guys
Just wanted to share this because this feels like a big step forward for me. Just put together some CSS grid layouts and posted them to codepen. I would love to get some feedback from you guys on these.

Hi Matt,
I think these are great. Grid layout is tricky, but once you get used to it you can do all kinds of cool stuff.

Next Steps:

.box-7 {
    background-color:#DF4304;
    display:grid;
    border-radius:10px;
    grid-area:3/5/6/7;
}
