Ah yes that’s just an example property. You can add more like margin and padding.
Example:
body.single-post h2{
margin-top: 20px;
margin-left: 30px;
}
You can do this for the rest of the headings as well.
Note if you want to every heading to have the same CSS properties applied to them you can do it like this:
body.single-post h2,
body.single-post h3,
body.single-post h4,
body.single-post h5,
body.single-post h6{
margin-top: 20px;
margin-left: 30px;
}
