transition-timing-function

transition-timing-function CSS 屬性用於表示各個被動畫特效影響的屬性的區間值計算方式。

本質上，這個屬性讓你使用加速度曲線來表示動畫變換的速度。

而每個可以動畫化的屬性使用一個 <timing-function> 作為加速度曲線。

你也許有許多時間函數，而你可以透過使用 transition-property 屬性來個別設置。如果有前述清單的數量超過時間函數的數量，則會使用預設值 ease；如果少於那多餘的時間函數會被忽略，在這兩種情況，CSS 宣告總會有效。

語法

/* Keyword */
transition-timing-function: ease;
transition-timing-function: ease-in;
transition-timing-function: ease-out;
transition-timing-function: ease-in-out;
transition-timing-function: linear;
transition-timing-function: step-start;
transition-timing-function: step-end;

/* 函數 */
transition-timing-function: steps(4, end);
transition-timing-function: cubic-bezier(0.1, 0.7, 1.0, 0.1);
transition-timing-function: frames(10);

/* 多個函數 */
transition-timing-function: ease, step-start, cubic-bezier(0.1, 0.7, 1.0, 0.1);

/* 全域值 */
transition-timing-function: inherit;
transition-timing-function: initial;
transition-timing-function: unset;

/* 包含 transition-property */
transition-property: width, height;
transition-timing-function: ease-in, ease-out; // ease-in to width and ease-out to height

值

<timing-function>: 每個 <timing-function> 連結到對應的動畫化屬性，請參考 transition-property。
