transition-duration

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨septiembre de 2015⁩.

La propiedad de CSS transition-duration establece el tiempo que debe tardar una animación de transición en completarse. Por defecto, el valor es de 0s, esto quiere decir que no se producirá ninguna animación.

Pruébalo

transition-duration: 500ms;
transition-property: margin-right;

transition-duration: 2s;
transition-property: background-color;

transition-duration: 2s;
transition-property: margin-right, color;

transition-duration: 3s, 1s;
transition-property: margin-right, color;

<section id="default-example">
  <div id="example-element">Hover to see<br />the transition.</div>
</section>

#example-element {
  background-color: #e4f0f5;
  color: #000;
  padding: 1rem;
  border-radius: 0.5rem;
  font: 1em monospace;
  width: 100%;
  transition: margin-right 2s;
}

#default-example:hover > #example-element {
  background-color: #909;
  color: #fff;
  margin-right: 40%;
}

Se puede especificar múltiples duraciones; cada duración va a ser aplicada a la propiedad correspondiente según lo especificado en la propiedad transition-property, que actuará como una lista maestra. Si se especifican menos duraciones en la lista maestra, el agente de usuario repetirá la lista de duraciones. Si hay más duraciones, la lista simplemente se trunca al tamaño correcto. En ambos casos, la declaración CSS sigue siendo válida

Sintaxis

css

/* <time> values */
transition-duration: 6s;
transition-duration: 120ms;
transition-duration: 1s, 15s;
transition-duration: 10s, 30s, 230ms;

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

Valores

<time>: El <time> indica la cantidad de tiempo que debe tomar la transición del valor anterior de una propiedad, al nuevo valor. Un tiempo de 0s indica que no ocurrirá ninguna transición, es decir, el cambio entre los dos estados será instantáneo. Un valor negativo para el tiempo hace que la declaración sea inválida.

Sintaxis Formal

transition-duration = 
  <time [0s,∞]>#
