+<p><a href="/ko/docs/Web/CSS">CSS</a> <strong>의사 클래스</strong>(가상 클래스)는 선택자에 추가하는 키워드로, 선택한 요소가 특별한 상태여야 만족할 수 있습니다. 예를 들어 {{cssxref(":hover")}}를 사용하면 포인터를 올렸을 때에만 글씨 색을 바꾸고 싶을 때 사용할 수 있습니다.</p>
+
+<pre class="brush: css notranslate">/* Any button over which the user's pointer is hovering */
+button:hover {
+  color: blue;
+}</pre>
+
+<p>의사 클래스를 사용하면 문서 트리 콘텐츠와 관련된 경우 뿐만 아니라 탐색기 히스토리({{cssxref(":visited")}} 등), 콘텐츠의 상태(특정 폼 요소에 적용한 {{cssxref(":checked")}} 등), 마우스의 위치(커서가 마우스 위인지 아닌지 알 수 있는 {{cssxref(":hover")}} 등)처럼 외부 인자와 관련된 경우에도 스타일을 적용할 수 있습니다.</p>

+<div class="blockIndicator note">
+<p><strong>참고</strong>: <a href="/ko/docs/Web/CSS/Pseudo-elements">의사 요소</a>는 의사 클래스와 달리 요소의 <strong>특정 부분</strong>에 스타일을 적용할 때 사용합니다.</p>
