Ways to align the `<ol>` number at the top vertically

I'm having trouble aligning my <ol> numbers vertically at the top of the list. I've created a sample on CodePen.

ol {
  list-style-type: decimal-leading-zero;
  font-size: 11px;
}

a {
  font-size: 80px;
  text-decoration: none;
}

<nav>
  <ol>
    <li><a href="#">Header One</a><span>This is some text, don't move me</span></li>
    <li><a href="#">Header Two</a><span>This is some text, don't move me</span></li>
    <li><a href="#">Header Three</a><span>This is some text, don't move me</span></li>
    <li><a href="#">Header Four</a><span>This is some text, don't move me</span></li>
  </ol>
</nav>

To create a custom counter, you can utilize the counter-reset and counter-increment CSS properties. To display the counter, use the before pseudo-element of each li element. You can align the counter to the top of the text by using vertical-align: top and adjusting the line-height.

Check out this demo:

ol {
  list-style: none;
  counter-reset: items;
  font-size: 11px;
}

ol li {
  counter-increment: items;
}

ol li:before {
  vertical-align: top;
  line-height: 45px;
}

ol li:before {
  content: "0" counter(items) ". ";
}

ol li:nth-child(n+10):before {
  content: counter(items) ". ";
}

a {
  font-size: 80px;
  text-decoration: none;
}

<nav>
  <ol>
    <li><a href="#">Header One</a><span>This is some text, don't move me</span></li>
    <li><a href="#">Header Two</a><span>This is some text, don't move me</span></li>
    <li><a href="#">Header Three</a><span>This is some text, don't move me</span></li>
    <li><a href="#">Header Four</a><span>This is some text, don't move me</span></li>
  </ol>

To resolve the issue with the tall anchor element, you can utilize vertical-align:top on the anchor tag. This adjustment should work well. Additionally, you may need to modify the line-height for the <a> tag and specify both line-height and margin for the <li> to ensure it appears as desired. If your goal is to align the <span>, consider adding vertical-align:bottom. After reviewing your CodePen example, I believe these changes will achieve the desired effect. Feel free to check out my version on CodePen.

ol {
  list-style-type: decimal-leading-zero;
  font-size: 11px;
  width: 300px;
}

li {
  margin: .6em 0;
  line-height: 1.6;
}

a {
  font-size: 80px;
  text-decoration: none;
  vertical-align: top;
  line-height: .8;
}

span {
  vertical-align: bottom;
}

<nav>
  <ol>
    <li><a href="#">Header One</a><span>This is some text, don't move me. Also, let's see how this looks if the line is long and there is more than one. And what if there's more text outside the span tag? </span> And what if there's more text outside the
      span tag? In that case, just make sure that the span and the li tag have the same line height.</li>
    <li><a href="#">Header Two</a><span>This is some text, don't move me</span></li>
    <li><a href="#">Header Three</a><span>This is some text, don't move me</span></li>

When floating blocks, their height is essentially ignored when it comes to line numbers. By wrapping the content of the <li> in a <div> and floating it to the left, the line numbers will appear above the div.

To ensure that the floated div takes up space and the items below appear below it, a clearfix can be used.

ol {
  list-style-type: decimal-leading-zero;
  font-size: 11px;
}

a {
  font-size: 80px;
  text-decoration: none;
}

.listContent {
  float: left;
}

/** Clearfix **/
li {
  content: "";
  clear: both;
}

<nav>
  <ol>    
    <li><div class="listContent"><a href="#">Header Two</a><span>This is some text, don't move me</span></div></li>
    <li><div class="listContent"><a href="#">Header Three</a><span>This is some text, don't move me</span></div></li>
    <li><div class="listContent"><a href="#">Header Four</a><span>This is some text, don't move me</span></div></li>
  </ol>
</nav>

In the near future, the ::marker pseudo-element may allow for specific styling of list markers. For example:

li::marker {
    vertical-align: top;
}

However, this feature is still in its early stages of browser support as of now. You can check the support matrix here.

Answer №4

In order to properly align the ::marker within the li element, it is necessary to align the element inside the li.

li {
    width: 350px;
}

div {
    display: inline-block;
    vertical-align: top;
}

<ol>
    <li>
        <div>
            Lorem ipsum dolor sit amet, consectetur adipiscing elit,
            sed do eiusmod tempor incididunt ut labore et dolore magna
            aliqua...
        </div>
    </li>
</ol>
