anchor()
アンカー要素の辺を基準に配置する
anchor()
関数は、アンカーに関連付けられた要素を、ターゲットとなるアンカー要素の辺を基準として配置するためのCSS関数です。
anchor()
関数の基本的な構文は下記のようになります。
<anchor()> = anchor( <anchor-name>? && <anchor-side>, <length-percentage>? )
<anchor-name>
ターゲットとなるアンカー要素の名前を指定します。anchor-name
プロパティで指定したアンカー要素の名前を指定します。指定が省略された場合、その要素の既定のアンカー(position-anchor
プロパティで指定されているアンカー要素)が使用されます。
<anchor-side>
ターゲットとなるアンカー要素の、対応する辺の位置を指定します。
<anchor-side>
として指定可能な値、およびキーワードは下記の通りです。
<anchor-side> = inside | outside
| top | left | right | bottom
| start | end | self-start | self-end
| <percentage> | center
inside
、outside
キーワードは、要素の配置に使用される inset
プロパティ(inset-block
や inset-inline
など)に応じて、アンカーボックスの一方の辺に解決されます。inside
は inset
プロパティ同様、アンカーボックスの内側位置を指し、outside
は逆の外側を指します。
top
、right
、bottom
、left
の各キーワードは、アンカーボックスの指定された辺を指します。
start
、end
、self-start
、self-end
の各キーワードは、要素の配置に使用される inset
プロパティ(inset-block
や inset-inline
など)と同じ軸のアンカーボックスの一方の辺を指します。
self-start
と self-end
は位置指定されたボックスの書字モードに基づき、start
と end
は位置指定されたボックスを包含するブロックの書字モードに基づいて解決されます。
<percentage>
値と center
キーワードは、start
と end
の間にある位置を割合で指定します。0%
は start
に、100%
は end
に相当します。center
は 50%
に相当します。
<length-percentage>
カンマ(,
)に続けて記述する <length-percentage>
値は、要素が位置指定されていない場合や、ターゲットとなるアンカー要素が存在しない場合に、フォールバックとして使用する距離です。
calc()
関数内での使用
anchor()
関数は、calc()
関数内でも使用できるため、例えば下記のように、アンカー要素の辺を基準にしながら、そこから 20px ずらす、といった指定も可能です。
.sample {
right: calc(anchor(left) + 20px);
position-anchor: --exampleAnchor;
position: fixed;
}

anchor()のサンプルソース
.content { position-anchor: --exampleAnchor; position: fixed; inset-block-start: anchor(end); inset-inline-start: anchor(self-end); margin: 0.25rem 0 0 0.25rem; }
