href="/ja/docs/Web/CSS/number"><code><number></code></a> として表される、入力の進行と出力の進行を関連付けます。これらの値について、 <code>0.0</code> は初期状態を表し、 <code>1.0</code> は最終状態を表します。</p> <p><img

<p>3 次ベジェ曲線は 4 個の点 P0, P1, P2, P3 によって定義されます。P0 と P3 は曲線の始点と終点を表します。CSS では、この点は座標の進行（横軸が入力の進行、縦軸が出力の進行）として固定されています。P0 は <code>(0, 0)</code> で進行の開始かつ初期状態を示します。P3 は <code>(1, 1)</code> で進行の終了かつ最終状態を示します。</p> <p>すべての 3 次ベジェ曲線が<a href="https://ja.wikipedia.org/wiki/%E9%96%A2%E6%95%B0_%28%E6%95%B0%E5%AD%A6%29" class="external" target="_blank">数学的な関数</a> とは限らないため、どの 3 次ベジェ曲線もイージング関数として適しているわけではありません。すなわち、曲線は横座標で 0 から 1 の値をとります。 P0 および P3 は CSS の定義で固定されているので、P1 および P2 の横座標の値が <code>[0, 1]</code> の範囲にある場合のみ、3 次ベジェ曲線は関数であり、それゆえ有効になります。</p> <p>P1 または P2 の縦軸が <code>[0, 1]</code> の範囲外の 3 次ベジェ曲線は、値が最終状態より遠くに行き、その後戻るようになることがあります。アニメーションでは、 <a href="/ja/docs/Web/CSS/left"><code>left</code></a> や <a href="/ja/docs/Web/CSS/right"><code>right</code></a> などのいくつかのプロパティで、これは一種の「跳ね返る」効果を生み出します。</p> <p><img src="/ja/docs/Web/CSS/easing-function/cubic-bezier_out_of_range.svg" alt="イージング関数 "cubic-bezier(0.3, 0.2, 0.2, 1.4)" のグラフ。一方は、ある入力の進行から始めるには出力の進行が 1
