Is it possible to change the order of list items using CSS3?

Question

Is it possible to change the order of list items using CSS3?

For example, if a list is coded in HTML in 1,2,3,4,5 order, but I want it to show in 5,1,2,3,4 order.

I'm using a CSS overlay to modify a Firefox extension, so I can't just change the HTML.

HTML Code

<ul>
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
</ul>

Answer 1

You can do it using flexbox.

Here's a fiddle I created for you: https://jsfiddle.net/x56hayht/

ul {
  display: flex;
  flex-direction: column;
}
ul li:first-child {
  order: 5;
}
ul li:nth-child(2) {
  order: 4;
}
ul li:nth-child(3) {
  order: 3;
}
ul li:nth-child(4) {
  order: 2;
}

<ul>
  <li>1</li>
  <li>2</li>
  <li>3</li>
  <li>4</li>
  <li>5</li>
</ul>

According to csstricks:

The order property is a sub-property of the Flexible Box Layout module.

Flex items are displayed in the same order as they appear in the source document by default.

The order property can be used to change this ordering.

Syntax:

order: number

Hope it helps. Cheers!

If you need just reverse, use:

ul {
    display: flex;
    flex-direction: column-reverse;
}

Answer 3

Yes, you can using the flexible box model's order css property. Be aware that the parent element must have display:flex set

ul {
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -moz-flex;
  display: -webkit-flex;
  display: flex;
  
  -moz-flex-flow: wrap;
  -webkit-flex-flow: wrap;
  flex-flow: wrap;
}
ul li {
  width: 100%
}
ul li:nth-of-type(1) {
  order: 2;
}
ul li:nth-of-type(2) {
  order: 3;
}
ul li:nth-of-type(3) {
  order: 4;
}
ul li:nth-of-type(4) {
  order: 5;
}
ul li:nth-of-type(5) {
  order: 1;
}

<ul>
  <li>1</li>
  <li>2</li>
  <li>3</li>
  <li>4</li>
  <li>5</li>
</ul>

Also be aware that not all browsers support the flexible box model as outlined here...http://caniuse.com/#feat=flexbox

However, there are quite a few polyfills out there you can use to bring support for older browsers if you need to support older browsers
