HTML ordered list options

I'm sure we all know the ordered list, which can be created by using a <ol> (Ordered list) element.

A basic structure looks like this:

<ol>
  <li>Number 1</li>
  <li>Number 2</li>
  <li>Number 3</li>
</ol>

And it will return this:

1. Number 1
2. Number 2
3. Number 3

But did you know there's super cool stuff we can do with ordered lists?

Defining an ordered list type permalink

By default, it will show the numbers as you can see above, but did you know we can specify the type in HTML?

<ol type="I">
  <li>Daily</li>
  <li>Dev</li>
  <li>Tips</li>
</ol>

Will return:

I. Daily II. Dev III. Tips

We can use the following types:

• 1: The default numeric list
• I: Uppercase roman numbers
• i: Lowercase roman numbers
• A: Uppercase letters
• a: Lowercase letters

Set the start number for ordered lists permalink

Next up is the start. By default, a list will start on one, but we can manually offset this.

<ol start="5">
  <li>Daily</li>
  <li>Dev</li>
  <li>Tips</li>
</ol>

This will render the following. It can be super useful in a list with paragraphs between.

5. Daily
6. Dev
7. Tips

Reverse an HTML ordered list permalink

Another cool thing we can do with lists is reverse them. It's just as easy as adding the reversed tag.

<ol reversed>
  <li>Daily</li>
  <li>Dev</li>
  <li>Tips</li>
</ol>

This will result in the following:

3 Daily 2 Dev 1 Tips

You can try all these out in the following Codepen.
