<h2 id="概要">概要</h2>

<p>The<strong> <code>padding-inline-start</code></strong> <a href="/en-US/docs/Web/CSS" title="CSS">CSS</a> property defines the logical inline start padding of an element, which maps to a physical padding depending on the element's writing mode, directionality, and text orientation. It corresponds to the {{cssxref("padding-top")}}, {{cssxref("padding-right")}}, {{cssxref("padding-bottom")}}, or {{cssxref("padding-left")}} property depending on the values defined for {{cssxref("writing-mode")}}, {{cssxref("direction")}}, and {{cssxref("text-orientation")}}.</p>

<p>It relates to {{cssxref("padding-block-start")}}, {{cssxref("padding-block-end")}}, and {{cssxref("padding-inline-end")}}, which define the other paddings of the element.</p>
