transition

嘗試一下

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 (en-US):active (en-US) 亦或是 使用 JavaScript 設定的狀態變化。

語法

/* 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

<single-transition> =
[ (en-US) none | (en-US) <single-transition-property> ] (en-US) || (en-US)
<time> (en-US) || (en-US)
<easing-function> || (en-US)
<time> (en-US)

<single-transition-property> =
all | (en-US)
<custom-ident> (en-US)

<easing-function> =
linear | (en-US)
<linear-easing-function> | (en-US)
<cubic-bezier-easing-function> | (en-US)
<step-easing-function>

<linear-easing-function> =
linear( <linear-stop-list> )

<cubic-bezier-easing-function> =
ease | (en-US)
ease-in | (en-US)
ease-out | (en-US)
ease-in-out | (en-US)
cubic-bezier( <number [0,1]> (en-US) , <number> (en-US) , <number [0,1]> (en-US) , <number> (en-US) )

<step-easing-function> =
step-start | (en-US)
step-end | (en-US)
steps( <integer> (en-US) [ (en-US), <step-position> ] (en-US)? (en-US) )

<linear-stop-list> =
[ (en-US) <linear-stop> ] (en-US)# (en-US)

<step-position> =
jump-start | (en-US)
jump-end | (en-US)
jump-none | (en-US)
jump-both | (en-US)
start | (en-US)
end

<linear-stop> =
<number> (en-US) && (en-US)
<linear-stop-length>? (en-US)

<linear-stop-length> =
<percentage> (en-US){1,2} (en-US)
