Transitions 讓你可以定義元件在兩個狀態之間切換的轉場效果。兩個不同狀態可以使用虛擬類別 定義,像是:hover:active 亦或是 使用 JavaScript 設定的狀態變化。

語法

css
/* Apply to 1 property */
/* property name | duration */
transition: margin-right 4s;

/* property name | duration | delay */
transition: margin-right 4s 1s;

/* property name | duration | timing function */
transition: margin-right 4s ease-in-out;

/* property name | duration | timing function | delay */
transition: margin-right 4s ease-in-out 1s;

/* Apply to 2 properties */
transition:
  margin-right 4s,
  color 1s;

/* Apply to all changed properties */
transition: all 0.5s ease-out;

/* Global values */
transition: inherit;
transition: initial;
transition: unset;

transition 屬性可以包含一個或多個轉場設定,每一項設定都以逗點分開。

每一項設定都描述著每一項屬性所對應的轉場效果(或是allnone這兩個特殊值) 。其包含了:

當每個轉場設定不等長時,請參見 當 property values list 之間不等長時... 。簡而言之,多餘的描述(超過實際被執行的數量)會直接被忽略。

標準語法

transition = 
<single-transition>#

<single-transition> =
[ none | <single-transition-property> ] ||
<time> ||
<easing-function> ||
<time>

<single-transition-property> =
all |
<custom-ident>

<easing-function> =
<linear-easing-function> |
<cubic-bezier-easing-function> |
<step-easing-function>

<linear-easing-function> =
linear |
<linear()>

<cubic-bezier-easing-function> =
ease |
ease-in |
ease-out |
ease-in-out |
<cubic-bezier()>

<step-easing-function> =
step-start |
step-end |
<steps()>

<linear()> =
linear( [ <number> && <percentage>{0,2} ]# )

<cubic-bezier()> =
cubic-bezier( [ <number [0,1]> , <number> ]#{2} )

<steps()> =
steps( <integer> , <step-position>? )

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