<p>The <strong><code>font-display</code></strong> descriptor determines how a font face is displayed based on whether and when it is downloaded and ready to use.</p>
<h2 id="The_font_display_timeline">The font display timeline</h2>
<p>The font display timeline is based on a timer that begins the moment the user agent attempts to use a given downloaded font face. The timeline is divided into the three periods below which dictate the rendering behavior of any elements using the font face.</p>
<dl>
<dt>Font block period</dt>
<dd>If the font face is not loaded, any element attempting to use it must render an <em>invisible</em> fallback font face. If the font face successfully loads during this period, it is used normally.</dd>
<dt>Font swap period</dt>
<dd>If the font face is not loaded, any element attempting to use it must render a fallback font face. If the font face successfully loads during this period, it is used normally.</dd>
<dt>Font failure period</dt>
<dd>If the font face is not loaded, the user agent treats it as a failed load causing normal font fallback.</dd>
</dl>
