::view-transition-new

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The ::view-transition-new CSS pseudo-element represents the "new" view state of a view transition — a snapshot live representation of the state after the transition.

During a view transition, ::view-transition-new is included in the associated pseudo-element tree as explained in The view transition pseudo-element tree. It is only ever a child of a ::view-transition-image-pair, and never has any children.

It is a replaced element and therefore can be manipulated with properties such as object-fit and object-position. It has natural dimensions equal to the content's size.

The following default styling is included in the UA stylesheet:

:root::view-transition-old(*),
:root::view-transition-new(*) {
  position: absolute;
  inset-block-start: 0;
  inline-size: 100%;
  block-size: auto;

  animation-duration: inherit;
  animation-fill-mode: inherit;
  animation-delay: inherit;
}

/* Keyframes for blending when there are 2 images */
@keyframes -ua-mix-blend-mode-plus-lighter {
  from {
    mix-blend-mode: plus-lighter;
  }
  to {
    mix-blend-mode: plus-lighter;
  }
}

@keyframes -ua-view-transition-fade-in {
  from {
    opacity: 0;
  }
}

Note: Additional view transition styles are also setup to animate ::view-transition-new. These are dynamically generated during the view transition; see the specification setup transition pseudo-elements and update pseudo-element styles sections for more details.

Syntax

::view-transition-new(<pt-name-selector>) {
  /* ... */
}

<pt-name-selector> can be one of the following values:

*: Causes the pseudo-element to match all view transition groups.
root: Causes the pseudo-element to match the default root view transition snapshot group created by the user agent to contain the view transition for the overall page. This group includes any element not assigned to its own specific view transition snapshot group via the view-transition-name property.
<custom-ident>: Causes the pseudo-element to match a specific view transition snapshot group created by assigning the given <custom-ident> to an element via the view-transition-name property.

Examples

figcaption {
  view-transition-name: figure-caption;
}

@keyframes grow-x {
  from {
    transform: scaleX(0);
  }
  to {
    transform: scaleX(1);
  }
}

@keyframes shrink-x {
  from {
    transform: scaleX(1);
  }
  to {
    transform: scaleX(0);
  }
}

::view-transition-old(figure-caption),
::view-transition-new(figure-caption) {
  height: auto;
  right: 0;
  left: auto;
  transform-origin: right center;
}

::view-transition-old(figure-caption) {
  animation: 0.25s linear both shrink-x;
}

::view-transition-new(figure-caption) {
  animation: 0.25s 0.25s linear both grow-x;
}
