<p>The requirement is for targets to be at least 24 by 24 CSS pixels in size. There are five exceptions:</p>

<ul>
<li><strong>Spacing:</strong> If a target is smaller than 24 by 24 CSS pixels but has sufficient spacing, it passes. The spacing is sufficient if for each target it is possible to draw a circle, centered on the target, with a diameter of 24 CSS pixels, without the circle overlapping the circle of any other other adjacent targets, nor the adjacent targets themselves.</li>
<li><strong>Spacing:</strong> If a target is smaller than 24 by 24 CSS pixels but has sufficient spacing, it passes. The spacing is sufficient if for each target it is possible to draw a circle, centered on the target, with a diameter of 24 CSS pixels, without the circle overlapping the circle of any other adjacent targets, nor the adjacent targets themselves.</li>
<li><strong>Equivalent:</strong> In cases where a target does not have an size equivalent to 24 by 24 CSS pixels, but there is another control that can achieve the underlying function that <em>does</em> meet the minimum size, the target can be excepted based on the "Equivalent" exception.</li>
<li><strong>Inline:</strong> The Success Criterion does not apply to inline targets in sentences, bulleted / numbers lists, or where the size of the target is constrained by the line-height of non-target text. This exception is allowed because text reflow based on viewport size makes it impossible for authors to anticipate where links may be positioned relative to one another. When multiple links are embedded in blocks of texts in smaller text sizes, maintaining a 24 CSS pixels offset between links in adjacent lines of text would require a large line height which can be undesirable in many design contexts. Also, inline numeric footnotes common in scientific texts may sometimes have a size well below 24 CSS pixels. <br/>Note: Stacked links in navigation structure that happen to use list markup do not count as inline links. Authors can anticipate the relative position of these links and provide sufficient target spacing.</li>
<li><strong>User agent control:</strong> Browsers have default renderings of some controls, such as the days of the month calendar in an <code>input type="date"</code>. As long as the author has not modified the user agent default, the target size for a "User agent control" is excepted.</li>
