ol list type not showing properly

please post your used code correctly – see https://codex.www.ads-software.com/Forum_Welcome#Posting_Code

seems that by default, and via the style.css of the theme, the ‘decimal’ style is set.

using the ‘text’ setting of the editor, you could add a style to the ol tag; example:

<ol style="list-style-type: lower-roman;">
 	<li>line one</li>
 	<li>line 2</li>
 	<li>line 3</li>
</ol>

Another approach — put this in the child theme’s style.css or in the Appearance / Edit CSS window.

ol.lower-alpha {
list-syle-type: lower-alpha;
{

ol.lower-roman {
list-style-type: lower-roman;
{

Then in you pages when you want to use lower alpha, use the class you want for the ol.

<ol class="lower-alpha">
  <li>item</li>
  <li>item</li>
  <li>item</li>
</ol>

<ol class="lower-roman">
  <li>item</li>
  <li>item</li>
  <li>item</li>
</ol>

Correction to the CSS–change each last opening curly bracket to a closing curly bracket! Duh!

ol.lower-alpha {
list-syle-type: lower-alpha;
}

ol.lower-roman {
list-style-type: lower-roman;
}
