<h3 id="Values">Values</h3>

<dl>
 <dt><code>none</code></dt>
 <dd>Is a keyword meaning that there is no explicit grid. Any columns will be implicitly generated and their size will be determined by the {{cssxref("grid-auto-columns")}} property.</dd>
 <dt><code>&lt;length&gt;</code></dt>
 <dd>Is a non-negative length.</dd>
 <dt><code>&lt;percentage&gt;</code></dt>
 <dd>Is a non-negative {{cssxref("percentage", "&lt;percentage&gt;")}} value relative to the inline size of the grid container. If the size of the grid container depends on the size of its tracks, then the percentage must be treated as <code>auto</code>.<br>
 The intrinsic size contributions of the track may be adjusted to the size of the grid container and increase the final size of the track by the minimum amount that would result in honoring the percentage.</dd>
 <dt><code>&lt;flex&gt;</code></dt>
 <dd>Is a non-negative dimension with the unit <code>fr</code> specifying the track’s flex factor. Each <code>&lt;flex&gt;</code>-sized track takes a share of the remaining space in proportion to its flex factor.
 <p>When appearing outside a <code>minmax()</code> notation, it implies an automatic minimum (i.e. <code>minmax(auto, &lt;flex&gt;)</code>).</p>
 </dd>
 <dt id="max-content"><code>max-content</code></dt>
 <dd>Is a keyword representing the largest maximal content contribution of the grid items occupying the grid track.</dd>
 <dt><code>min-content</code></dt>
 <dd>Is a keyword representing the largest minimal content contribution of the grid items occupying the grid track.</dd>
 <dt><code>{{cssxref("minmax", "minmax(min, max)")}}</code></dt>
 <dd>Is a functional notation that defines a size range greater than or equal to <em>min</em> and less than or equal to <em>max</em>. If <em>max</em> is smaller than <em>min</em>, then <em>max</em> is ignored and the function is treated as <em>min</em>. As a maximum, a <code>&lt;flex&gt;</code> value sets the track’s flex factor. It is invalid as a minimum.</dd>
 <dt id="auto"><code>auto</code></dt>
 <dd>Is a keyword that is identical to maximal content if it's a maximum. As a minimum it represents the largest minimum size (as specified by {{cssxref("min-width")}}/{{cssxref("min-height")}}) of the grid items occupying the grid track.</dd>
 <dd>
 <p class="note">Note: <code>auto</code> track sizes (and only <code>auto</code> track sizes) can be stretched by the {{cssxref("align-content")}} and {{cssxref("justify-content")}} properties.</p>
 </dd>
 <dt id="fit-content()"><code>{{cssxref("fit-content", "fit-content( [ &lt;length&gt; | &lt;percentage&gt; ] )")}}</code></dt>
 <dd>Represents the formula <code>min(max-content, max(auto, <var>argument</var>))</code>, which is calculated similar to <code>auto</code> (i.e. <code>minmax(auto, max-content)</code>), except that the track size is clamped at <var>argument</var> if it is greater than the <code>auto</code> minimum.</dd>
 <dt>{{cssxref("repeat", "repeat( [ &lt;positive-integer&gt; | auto-fill | auto-fit ] , &lt;track-list&gt; )")}}</dt>
 <dd>Represents a repeated fragment of the track list, allowing a large number of columns that exhibit a recurring pattern to be written in a more compact form.</dd>
