CSS Styles
Introduction
For most styles, the semantic html tags are separated from the styling, which gets appied by using classes. There are however some html elements, which are so specialized, that you would only use them for styling. Jhana UI recognizes this and automatically applies styling to these. They include: <b>, <strong>, <i>, <em>, <kbd>, <hr> (look below)
Just use CTRL+O or CTRL+O or CTRL O . I still have to decide which of those works best.
But in most cases, you will use class names. Here are some of those optimal for spans: italic, underline, highlight, link, monospace
Headings
Just add the h[1-5] class to any element.
