transition-duration
は CSS のプロパティで、トランジションによるアニメーションが完了するまでの所要時間を秒数またはミリ秒数で指定します。既定値は 0s
であり、これはアニメーションを実行しないことを示します。
このプロパティには複数の所要時間を指定することができます。それぞれの時間は、マスターリストを務める {{ cssxref("transition-property") }} プロパティの指定値で対応するプロパティに適用されます。指定した所要時間の数がマスターリストで指定したプロパティの数より少ない場合は、不足している値は初期値 (0s
) になります。また所要時間の数が多い場合は、リストを適切な長さに切り詰めます。どちらの場合も、CSS の宣言として妥当です。
/* <time> 値 */ transition-duration: 6s; transition-duration: 120ms; transition-duration: 1s, 15s; transition-duration: 10s, 30s, 230ms; /* グローバル値 */ transition-duration: inherit; transition-duration: initial; transition-duration: unset;
<time>
0s
の時間は、遷移が起こらないこと、すなわち、2 つの状態間の切り替えが瞬間的であることを示します。負の値を指定すると、宣言は無効になります。{{CSSInfo}}
