Reply To: [Solved] Alternating column widths at set intervals

[grimski]

Doh! I think it was just the prefixes, for some reason I thought Chrome would still pick up the column-width and column-gap rules without them.

As I’m on a 27″ iMac, I’ve realised I’ll need a lot of items to fill the screen or I’ll need to change the height/width of each <li> so they’re taller. Otherwise The amount of list-items will fit into 2 or 3 columns on the screen due to the browser height!

Thanks again for all your help. I saved your original CSS if it helps (width browser prefixes):

ul {
  list-style: none;
  padding: 0;
}

li {
  background: rgba(255, 0, 0, .40);
  padding: 0.5% 0;
  height: 14.4%;
  display: inline-block;
  margin: 0.4% 0.4% 0.4% 0!important;
}

ul {
  counter-reset: ulli;
  -webkit-column-width: 350px;
  -webkit-column-gap: 1px;
  -moz-column-width: 350px;
  -moz-column-gap: 1px;
  column-width: 350px;
  column-gap: 1px;
}

html,
body,
ul {
  height: 100%;
  margin: 0;
}

li:before {
  counter-increment: ulli;
  content: counter(ulli);
}

li:nth-child(1n) {
  width: 48.75%;
  background: lightgray;
}

li:nth-child(7n+1) {
  width: 99%;
  background: #00f;
}
