Hyphenation Explained:
Regular text, references, and sublines are getting hyphenated by the user's browser. All common major browsers apply proper hyphenation in the most languages.
The main page headline (H1) and the chapter headlines (H2) are not hyphenated on desktop screens. For tablet and mobile hyphenation is enabled.
Web browsers will support more sophisticated hyphenation rules for websites. A new rule, the hyphenate-limit-chars property, will tell the browser how many characters a word should be before it’s hyphenated, as well as the minimum number of characters before and after the hyphen. This way, we can avoid awkward hyphenations, giving us an extra degree of control when it comes to how words flow from line to line.
