Make ABC Ordered List Items Have Bold Style

I have an html Ordered list with type set to "A"

<ol type="A">...</ol>

Thus, each list item will start with A, B, C, etc.

I would like to style the A, B, C letters to be bold. I have tried setting font-weight:bold; via css, but it didn't work. Any suggestions on how to do this?

a bit of a cheat, but it works:

HTML:

<ol type="A" style="font-weight: bold;">
  <li><span>Text</span></li>
  <li><span>More text</span></li>
</ol>

CSS:

li span { font-weight: normal; }

As an alternative and superior solution, you could use a custom counter in a before element. It involves no extra HTML markup. A CSS reset should be used alongside it, or at least styling removed from the ol element (list-style-type: none, reset margin), otherwise the element will have two counters.

<ol>
    <li>First line</li>
    <li>Second line</li>
</ol>

CSS:

ol {
    counter-reset: my-badass-counter;
}
ol li:before {
    content: counter(my-badass-counter, upper-alpha);
    counter-increment: my-badass-counter;
    margin-right: 5px;
    font-weight: bold;
}

Are you sure you correctly applied the styles, or that there isn't another stylesheet interfering with your lists? I tried this:

<ol type="A">
<li><span class="label">Text</span></li>
<li><span class="label">Text</span></li>
<li><span class="label">Text</span></li>
</ol>

Then in the stylesheet:

ol {font-weight: bold;}
ol li span.label {font-weight:normal;}

And it bolded the A, B, C etc and not the text.

(Tested it in Opera 9.6, FF 3, Safari 3.2 and IE 7)

I know this question is a little old, but it still comes up first in a lot of Google searches. I wanted to add in a solution that doesn't involve editing the style sheet (in my case, I didn't have access):

<ol type="A">
  <li style="font-weight: bold;">
    <p><span style="font-weight: normal;">Text</span></p>
  </li>
  <li style="font-weight: bold;">
    <p><span style="font-weight: normal;">More text</span></p>
  </li>
</ol>

You could do something like this also:

ol {
  font-weight: bold;
}

ol > li > * {
  font-weight: normal;
}

So you have no "style" attributes in your HTML

You could do something like this also:

<ol type="A" style="font-weight: bold;">

<li style="padding-bottom: 8px;">****</li>

It is simple code for the beginners.

This code is been tested in "Mozilla, chrome and edge..

Another even shorter solution is to make use of li::marker now widely supported. Like so:

ol li::marker {
		font-weight: bold;
}
