clip-path
は CSS のプロパティで、要素のどの部分を表示するかを設定するクリッピング領域を作ります。具体的には、領域の内部の部分は表示され、外側の部分は非表示になります。

clip-path
プロパティは、以下に挙げた値のうちの一つまたは組み合わせで指定します。
<clip-source>
<geometry-box>
値で寸法と位置が定義されるシェイプです。ジオメトリボックスが指定されない場合、参照ボックスとして border-box
が使用されます。<geometry-box>
<basic-shape>
と共に指定された場合、この値は基本シェイプの参照ボックスを定義します。単独で指定された場合、指定のボックスの辺を、角の形 ({{cssxref("border-radius")}} など) を含めてクリッピングパスにします。ジオメトリボックスは以下の値のうちの一つが指定できます。margin-box
border-box
padding-box
content-box
fill-box
stroke-box
view-box
viewBox
属性で指定された座標系の原点に位置し、参照ボックスの寸法は viewBox
属性の width および height 値に設定されます。none
注: 計算値が none
以外の場合は、新しい重ね合わせコンテキストを生成します。これは、 {{cssxref("opacity")}} が 1
以外の値の場合と同様です。
