A styled ordered list whose nested list should have numbers with letters using CSS counter property

I want to add a letter to an <li>-element from a my under <ol> like from my question: 

body { counter-reset: item; }

ol.numbered_style li:before
{
    counter-increment:item;
    margin-bottom:5px;
    margin-right:10px;
    content:counter(item);
    background:blue;
    border-radius:100%;
    color:white;
    width:1.2em;
    text-align:center;
    display:inline-block;
}
ol.numbered_style.start_3{
  counter-reset: item 2; 
}

ol.none, ul.none,ol.numbered_style { list-style: none; }
<ol class="numbered_style">
	<li>first</li>
	<li>second</li>
	<li>third  Lorem Ipsum
		<ol class="numbered_style start_3">
			<li>missing an a after the number</li>
			<li>missing a b after the number</li>
			<li>missing a c after the number</li>
		</ol>
	</li>
</ol>
I have tried li::before { content: " a ";}, but this didn't work. I also want a solution, in which adding in a second counter can generate the next elements with the following alphanumeric pattern like list-style-type: lower-alpha;

Solution

  • Sure, you can do anything that the <ol> can do.

    ol.numbered_style.start_3{
  counter-reset: item2; 
}

ol.numbered_style.start_3 li:before {
    counter-increment:item2;
    content:counter(item2, upper-latin);
}/* List Style Type========^----------^*/

    Counter List Style Types

    • decimal ------------------------------- 1, 2, 3, ...

    • decimal-leading-zero -------------- 01, 02, 03, ... 09, 10, 11, ...

    • lower-alpha, lower-latin ----------- a, b, c, ... z, aa, ab, ...

    • upper-alpha, upper-latin ---------- A, B, C, ... Z, AA, AB, ...

    • lower-roman ------------------------ i, ii, iii, iv, v, vi, ...

    • upper-roman ------------------------ I, II, III, IV, V, VI, ...

    • asterisks ----------------------------- *, **, ***,...
