Hi there,
you can add bottom margin to each of the list items. This CSS will apply to all ordered lists within the content of your post.
.entry-content ol li {
margin-bottom: 2em;
}
If you want it to apply to unordered lists as well you can use this:
.entry-content ol li,
.entry-content ul li {
margin-bottom: 2em;
}
Please note that UL lists are quite commonly used in HTML from other plugins, and if they do not have specific styles the above CSS may affect them.
