Revision 1055608 of inline-size

<p>{{CSSRef}}{{SeeCompatTable}}</p>

<h2 id="Summary">Summary</h2>

<p>The <strong><code>inline-size</code></strong> <a href="/en-US/docs/Web/CSS" title="CSS">CSS</a> property defines the horizontal or vertical size of an element's block depending on its writing mode. It corresponds to the {{cssxref("width")}} or the {{cssxref("height")}} property depending on the value defined for {{cssxref("writing-mode")}}.</p>

<p>If the writing mode is vertically oriented, the value of <code>inline-size</code> relates to the height of the element, otherwise it relates to the width of the element. It relates to {{cssxref("block-size")}}, which defines the other dimension of the element.</p>
