How do I get 2 columns instead of one?

I've checked my work (no typos, everything is closed off) and I still don't see where I've went wrong:

2 things you need to change on your CSS.

  1. your #gallery li is missing the % symbol to make it a percentage width.
  2. because you're floating elements your footer doesn't know its place. add clear: both to your footer

View Below

#gallery li {
  float: left;
  width: 45%;
  margin: 2.5%;
  background-color:#f5f5f5;
  color: #bdc3c7;
}

footer {
  font-size: 0.75em;
  text-align: center;
  padding-top: 50px;
  color: #ccc;
  clear: both;
}

Oh, thank you! I way over looked that percentage sign!

Hi Christina--

I see that you are floating all the html gallery li to the left. You may try creating a div and float some to the right. Hope this helps. Also, I noticed there is no <meta name= "viewport" width="device width"> in the head tag. That can cause trouble down the road. Hope this helped!

What do you mean there is no 'head tag'? Like, none in the CSS document? Which lesson did they go over it again? Plus I tried floating some to the right and it didn't do anything to my page.

45% for the width, not 45 :)
