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

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

公式語法

<timing-function>#

where
<timing-function> = linear | <cubic-bezier-timing-function> | <step-timing-function>

where
<cubic-bezier-timing-function> = ease | ease-in | ease-out | ease-in-out | cubic-bezier(<number>, <number>, <number>, <number>)
<step-timing-function> = step-start | step-end | steps(<integer>[, <step-position>]?)

where
<step-position> = jump-start | jump-end | jump-none | jump-both | start | end
