Words are not broken at line breaks, even if characters inside the words suggest line break points. Lines will only wrap at whitespace.

Words are broken for line-wrapping only where characters inside the word suggest line break opportunities. See Suggesting line break opportunities below for details.

The browser is free to automatically break words at appropriate hyphenation points, following whatever rules it chooses. However, suggested line break opportunities (see Suggesting line break opportunities below) will override automatic break point selection when present.

The "hard" hyphen character indicates a visible line break opportunity. Even if the line is not actually broken at that point, the hyphen is still rendered.

An invisible, "soft" hyphen. This character is not rendered visibly; instead, it marks a place where the browser should break the word if hyphenation is necessary. In HTML, use ­ to insert a soft hyphen.
