Skye: Format blog titles

Hey—Wondering if anyone knows a way to format blog titles on the Tudor template (Skye family). I'd like to be able to italicize just a part of titles when needed, and if possible add line breaks as well.

So that something like "Title: Subtitle" could become:

Title
Subtitle

If it helps, the site is willfenstermaker.com/writing

Thanks!

@wfenstermaker Try renaming title to

Title <span class="kl">Subtitle</span>

then insert this CSS to Home > Design > Custom CSS

.kl {
  display: block;
  font-style: italic;
}

@tuanphan thanks! but didn't appear to work :/

Any HTML or markdown I put in the blog title field just shows up as part of the title
