<ul>
<li><strong>Minimum area:</strong> The <a>focus indication area</a> is greater than or equal to a 1 <a>CSS pixel</a> border of the focused control, or has a thickness of at least 8 CSS pixels along the shortest side of the element.</li>
<li><strong>Change of contrast:</strong> The color change for the focus indication area has a contrast ratio of at least 3:1 with the colors of the unfocused state.</li>
<li><strong>Adjacent contrast:</strong> The focus indication area has a contrast ratio of at least 3:1 against all adjacent colors for the minimum area or greater, or has a thickness of at least 2 CSS pixels.</li>
<li><strong>Minimum area:</strong> The area of the <a>focus indicator</a> is at least as large as as the area of a 1 <a>CSS pixel</a> thick perimeter of the focused control, or the focus indicator has a thickness of at least 8 CSS pixels along the shortest side of the user interface component.</li>
<li><strong>Change of contrast:</strong> The pixels making up the minimum focus indicator area achieve at least a 3:1 contrast between their colors in the focused and unfocused states. </li>
<li><strong>Adjacent contrast:</strong> The focus indicator contrasts at least 3:1 against all adjacent colors, or has a thickness of at least 2 CSS pixels.</li>
<li><strong>Not fully obscured:</strong> The item with focus is not entirely hidden by author-created content.</li>
</ul>
<p class="note">A keyboard focus indicator which has a pattern or gradient may have parts that do not meet the 3:1 contrast ratio for the change of contrast, as long as an area equal to the minimum does meet the contrast ratio.</p>
