+# Display
+

+  Use the display utility classes to set the display of an element to any possible display CSS
+  value.
+</div>
+
+The naming convention for display utilities follows this pattern:
+
+- For all breakpoints (<code>{firstBreakpoint}</code> and up): `d-{display}`
+- Starting from a specific breakpoint ({breakpoints.map(([b, isLast]) => (<span key={b}><code>{b}</code>{isLast ? ', ' : ''}</span>))}): `d-{breakpoint}-{display}`
+
+### Available display values
+
+The available display utilities values are the following:
+
+<ul>
+  {forEach(displayOptions, function ({ value }) {
+    return <li>{value}</li>;
+  })}
+</ul>
+
+### Usage
+
+To set a display on an element, simply add a `d-{display}` class to it.
