Hyphenation
Section titled HyphenationOur hyphenation classes determine when text that wraps across multiple lines is hyphenated. You can prevent hyphenation entirely, or allow the browser to automatically hypenate.
<p class="hyphens-none">…</p>
<p class="hyphens-auto">…</p>.ow-break-word.
.ow-break-word shouldn’t be necessary since breaks are implied by hyphenation rules.
