<p>CSS <strong><code>width</code></strong> 속성은 요소의 너비를 설정합니다. 기본값은 콘텐츠 영역의 너비이지만, {{cssxref("box-sizing")}}이 <code>border-box</code>라면 테두리 영역의 너비를 설정합니다.</p>

<div>{{EmbedInteractiveExample("pages/css/width.html")}}</div>



<p>{{cssxref("min-width")}}와 {{cssxref("max-width")}} 속성은 <code>width</code>를 덮어씁니다.</p>
