<h2 id="introduction">Introduction</h2>
<p><em>This section is not normative.</em>
<p>
This document introduces new CSS features to enable <em>implicit transitions</em>, which describe how CSS properties can be made to change smoothly from one value to another over a given duration.
</p>
<h2>
Transitions
</h2>
<p>
Normally when the value of a CSS property changes, the rendered result is instantly updated, with the affected elements immediately changing from the old property value to the new property value. This section describes a way to specify transitions using new CSS properties. These properties are used to animate smoothly from the old state to the new state over time.
</p>
<p>
For example, suppose that transitions of one second have been defined on the <span class="prop-name">'left'</span> and <span class="prop-name">'background-color'</span> properties. The following diagram illustrates the effect of updating those properties on an element, in this case moving it to the right and changing the background from red to blue. This assumes other transition parameters still have their default values.
</p>
<div class="figure">
<img src="transition1.png" alt="">
</div>
<p class="caption">
Transitions of <span class="prop-name">'left'</span> and <span class="prop-name">'background-color'</span>
</p>
<p>
Transitions are a presentational effect. The computed value of a property transitions over time from the old value to the new value. Therefore if a script queries the computed style of a property as it is transitioning, it will see an intermediate value that represents the current animated value of the property.
</p>
<p>
Only animatable CSS properties can be transitioned. See the table at the end of this document for a list
of properties that are animatable.
</p>
<p>
The transition for a property is defined using a number of new properties. For example:
</p>
<div class="example">
<p style="display:none">
Example(s):
</p>
<pre>
div {
transition-property: opacity;
transition-duration: 2s;
}
</pre>The above example defines a transition on the <span class="prop-name">'opacity'</span> property that, when a new value is assigned to it, will cause a smooth change between the old value and the new value over a period of two seconds.
</div>
<p>
Each of the transition properties accepts a comma-separated list, allowing multiple transitions to be defined, each acting on a different property. In this case, the individual transitions take their parameters from the same index in all the lists. For example:
</p>
<div class="example">
<p style="display:none">
Example(s):
</p>
<pre>
div {
transition-property: opacity, left;
transition-duration: 2s, 4s;
}
</pre>This will cause the <span class="prop-name">'opacity'</span> property to transition over a period of two seconds and the left property to transition over a period of four seconds.
</div><!-- ======================================================================================================= -->
<h3>
The <span class="prop-name">'transition-property'</span> Property
</h3>
<p>
The <span class="prop-name">'transition-property'</span> property specifies the name of the CSS property to which the transition is applied.
</p>
<div class="issue">
We may ultimately want to support a keypath syntax for this property. A keypath syntax would enable different transitions to be specified for components of a property. For example the blur of a shadow could have a different transition than the color of a shadow.
</div>
<table class="propdef">

<tr>
<td>
<em>Name:</em>
</td>
<td>
<dfn id="transition-property">transition-property</dfn>
</td>

<p>
A value of 'none' means that no property will transition. A value of
'all' means that every property that is able to undergo a transition
will do so. Otherwise, a list
of properties to be transitioned is given.
</p>
<div class="issue">
We need to generate a list of properties that can be transitioned.
</div>
<div class="issue">
Is "none" even a useful value if the initial value is "all"? The syntax is more elegant if transition-duration defaults to 0 and this property defaults to "all", but another option is to default this property to "none" and duration to something reasonable, e.g., 250ms. This would force an author to specify transition-property in the shorthand all the time though.

This property specifies how long the transition from the old value to the new value should take. By default the value is '0', meaning that the transition is immediate (i.e. there will be no animation). A negative value for <span class="prop-name">transition-duration</span> is treated as '0'.

The <span class="prop-name">'transition-timing-function'</span> Property
</h3>
<p>
The <span class="prop-name">'transition-timing-function'</span> property
describes how the intermediate values used during a transition will be
calculated. It allows for a transition to change speed over its
duration. These effects are commonly called <em>easing</em> functions.
In either case, a mathematical function that provides a smooth curve is
used.
</p>
<p>
The timing function is specified using a <a
href="http://en.wikipedia.org/wiki/B%C3%A9zier_curve#Cubic_B.C3.A9zier_curves">cubic
bezier curve</a>, which is defined by four control points, P<sub>0</sub>
through P<sub>3</sub> (see Figure 1). P<sub>0</sub> and P<sub>3</sub>
are always set to (0,0) and (1,1). The <span
class="prop-name">'transition-timing-function'</span> property is used
to specify the values for points P<sub>1</sub> and P<sub>2</sub>. These
can be set to preset values using the keywords listed below, or can be
set to specific values using the <span
class="prop-value">'cubic-bezier'</span> function. In the <span
class="prop-value">'cubic-bezier'</span> function, P<sub>1</sub> and
P<sub>2</sub> are each specified by both an X and Y value.
</p>
<div class="figure">
<img src="TimingFunction.png" alt="The timing function is a
smooth curve from point P0 = (0,0) to point P3 = (1,1). The
length and orientation of the line segment P0-P1 determines
the tangent and the curvature of the curve at P0 and the
line segment P2-P3 does the same at P3.">
</div>
<p class="caption">
Timing Function Control Points
</p>
<p>
The timing function takes as its input the current elapsed percentage of
the transition duration and outputs a percentage that determines how
close the transition is to its goal state.

<h3>
The <span class="prop-name">'transition-delay'</span> Property
</h3>
<p>
The <span class="prop-name">'transition-delay'</span> property defines when the transition will start. It allows a transition to begin execution some some period of time from when it is applied. A <span class="prop-name">'transition-delay'</span> value of '0' means the transition will execute as soon as the property is changed. Otherwise, the value specifies an offset from the moment the property is changed, and the transition will delay execution by that offset.
</p>
<p>
If the value for <span class="prop-name">'transition-delay'</span> is a negative time offset then the transition will execute the moment the property is changed, but will appear to have begun execution at the specified offset. That is, the transition will appear to begin part-way through its play cycle. In the case where a transition has implied starting values and a negative <span class="prop-name">'transition-delay'</span>, the starting values are taken from the moment the property is changed.

<div class="issue">
What should happen when a value is changed midway through a transition? One option is to simply begin a new transition from the current position. However things get interesting when from/to values are being flipped. For example you'd like symmetry on fade-in/fade-out hover effects if the user rolls over the object and rolls out before the animation finishes. This implies that
5DC1
there needs to be a convenient and straightforward rule for running transitions in reverse under certain circumstances. This could be controlled via a new property, or could perhaps be done simply by detecting when the from/to values are flipped.

<h2>
Transition Events
</h2>
<p>
The completion of a CSS Transition generates a corresponding <a href="http://www.w3.org/TR/DOM-Level-2-Events/events.html">DOM Event</a>.
An event is fired for each property that undergoes a transition.
This allows a content developer to perform actions that synchronize
with the completion of a transition.
</p>
<p>
Each event provides the name of the property the transition is
associated with as well as the duration of the transition.

<h2>
Animation of property types
</h2>
<p>
The following describes how each property type undergoes transition or
animation.
</p>
<ul>
<li>
<strong>color</strong>: interpolated via red, green, blue and alpha
components (treating each as a number, see below).
</li>
<li>
<strong>length</strong>: interpolated as real numbers.
</li>
<li>
<strong>percentage</strong>: interpolated as real numbers.
</li>
<li>
<strong>integer</strong>: interpolated via discrete steps (whole
numbers). The interpolation happens in real number space and is
converted to an integer using <code>floor()</code>.
</li>
<li>
<strong>number</strong>: interpolated as real (floating point)
numbers.
</li>
<li>
<strong>transform list</strong>: see
CSS Transforms specification [[!CSS3-2D-TRANSFORMS]].
</li>
<li>
<strong>rectangle</strong>: interpolated via the x, y,
width and height components (treating each as a number).
</li>
<li>
<strong>visibility</strong>: interpolated via a discrete
step. The interpolation happens in real number space between 0 and 1,
where 1 is "visible" and all other values are "hidden".
</li>
<li>
<strong>shadow</strong>: interpolated via the color, x, y
and blur components (treating them as color and numbers where
appropriate).
</li>
<li>
<strong>gradient</strong>: interpolated via the
positions and colors of each stop. They must have the same type
(radial or linear) and same number of stops in order to be animated.
</li>
<li>
<strong>paint server</strong> (SVG): interpolation is only supported
between</strong>: gradient to gradient and color to color. They then
work as above.
</li>
<li>
<strong>space-separated list of above</strong>: each item in the list
is interpolated using the rules above.
</li>
</ul>
