<h2>Introduction</h2>
<p><em>This section is not normative.</em>
<p>
The CSS <a href="http://www.w3.org/TR/REC-CSS2/visuren.html">visual
formatting model</a> describes a coordinate system within which each
element is positioned. Positions and sizes in this coordinate space can
be thought of as being expressed in pixels, starting in the upper left
corner of the parent with positive values proceeding to the right and
down.
</p>
<p>
This coordinate space can be modified with the <span
class="prop-name">'transform'</span> property. Using transform, elements
can be translated, rotated and scaled in two dimensional space.
The coordinate space
behaves as described in the <a
href="http://www.w3.org/TR/SVG/coords.html#EstablishingANewUserSpace">coordinate
system transformations</a> section of the SVG 1.1 specification. This is
a coordinate system with two axes: the X axis increases horizontally to
the right; the Y axis increases vertically downwards.
</p>
<p>
Specifying a value other than 'none' for the <span
class="prop-name">'transform'</span> property establishes a new
<em>local coordinate system</em> at the element that it is applied to.
Transformations are cumulative. That is, elements establish their local
coordinate system within the coordinate system of their parent. In this
way, a <span class="prop-name">'transform'</span> property effectively
accumulates all the <span class="prop-name">'transform'</span>
properties of its ancestors. The accumulation of these transforms
defines a <em>current transformation matrix (CTM)</em> for the element.
</p>
<p>
The transform property does not affect the flow of the content
surrounding the transformed element. However, the value of the overflow
area takes into account transformed elements. This behavior is similar
to what happens when elements are translated via relative positioning.
Therefore, if the value of the <span class="prop-name">'overflow'</span>
property is <span class="prop-value">'scroll'</span> or <span
class="prop-value">'auto'</span>, scrollbars will appear as needed to
see content that is transformed outside the visible area.
</p>
<p>
Any value other than 'none' for the transform results in the creation of
both a stacking context and a containing block. The object acts as
though position: relative has been specified, but also acts as a
containing block for fixed positioned descendants.
</p>
<div class="todo">
Need to go into more detail here about why fixed positioned objects
should do this, i.e., that it's much harder to implement otherwise.
</div>
<div class="issue">
Transforms should perhaps be allowed to affect layout. Using the
position property to do this seems to be the logical choice, but there
are lots of questions about how this would work.
</div>
<div class="issue">
What do fixed backgrounds do in transforms? They should probably ignore
AB46
the transform completely, since - even transformed - the object should
be acting as "porthole" through which the fixed background can be viewed
in its original form.
</div>
<div class="issue">
This property should also be applicable to SVG elements.
</div>
<div class="issue">
We also need to specify that SVG transforms *do* combine with this
transform, e.g., if a <foreignObject> is inside transformed SVG
and then defines a transform of its own. This means we may potentially
have to examine the current SVG transform and combine with it to set the
correct transform.

<h2 id="transform-property">
The <span class="prop-name">'transform'</span> Property
</h2>
<p>
A two-dimensional transformation is applied to an element through the <span
class="prop-name">'transform'</span> property. This property contains a
list of <a href="#transform-functions">transform functions</a>. The
final transformation value for an element is obtained by performing a
matrix concatenation of each entry in the list. The set of transform
functions is similar to those allowed by SVG.

<h2 id="transform-origin-property">
The <span class="prop-name">'transform-origin'</span> Property
</h2>
<p>
The <span class="prop-name">'transform-origin'</span> property
establishes the origin of transformation for an element. This property
is applied by first translating the element by the negated value of the
property, then applying the element's transform, then translating by the
property value. This effectively moves the desired transformation origin
of the element to (0,0) in the local coordinate system, then applies
the element's transform, then moves the element back to its original
position.

Transform Values and Lists
</h2>
<p>
The <translation-value> values are defined as [<percentage> | <length>]. All other value types are described <a href="http://www.w3.org/TR/REC-CSS2/syndata.html#values">as CSS types</a>. If a list of transforms is provided, then the net effect is as if each transform had been specified separately in the order provided. For example,
</p>
<pre>
<div style="transform:translate(-10px,-20px) scale(2) rotate(45deg) translate(5px,10px)"/>
</pre>
<p>
is functionally equivalent to:
</p>
<pre>
<div style="transform:translate(-10px,-20px)">
<div style="transform:scale(2)">
<div style="transform:rotate(45deg)">
<div style="transform:translate(5px,10px)">
</div>
</div>
</div>
</div>
</pre>
<div class="example">
<pre>
div {
transform: translate(100px, 100px);
}
</pre>Move the element by 100 pixels in both the X and Y directions.
<div class="figure">
<img src="transform1.png" alt="The 100px translation in X and Y">
</div>
</div>
<div class="example">
<pre>
div {
height: 100px; width: 100px;
transform: translate(80px, 80px) scale(1.5, 1.5) rotate(45deg);
}
</pre>Move the element by 80 pixels in both the X and Y directions, then scale the element by 150%, then rotate it 45 degrees clockwise about the Z axis. Note that the scale and rotate operate about the center of the element, since the element has the default transform-origin of 50% 50%.

<h2 id="animation">
Transitions and animations between transform values
</h2>
<p>
When animating or transitioning the value of a transform property
the rules described below are applied. The 'from' transform is
the transform at the start of the transition or current keyframe. The
'end' transform is the transform at the end of the transition or
current keyframe.
</p>
<ul>
<li>
If the 'from' and 'to' transforms are both single functions
of the same type:
<ul>
<li>
For translate, translateX, translateY, translateZ, scale,
scaleX, scaleY, rotate, skewX and skewY functions:
<ul>
<li>
the individual components of the function are
interpolated numerically.
</li>
</ul>
</li>
<li>
For matrix:
<ul>
<li>
the matrix is
decomposed using <a
href="http://tog.acm.org/GraphicsGems/gemsii/unmatrix.c">the
method described by unmatrix</a> into separate translation,
scale, rotation and skew matrices, then each
decomposed matrix is interpolated numerically, and finally
combined in order to produce a resulting 3x2 matrix.
</li>
</ul>
</li>
</ul>
</li>
<li>
If both the 'from' and 'to' transforms are "none":
<ul>
<li>
There is no interpolation necessary
</li>
</ul>
</li>
<li>
If one of the 'from' or 'to' transforms is "none":
<ul>
<li>
The 'none' is replaced by an equivalent identity function list for
the corresponding transform function list.
<p>
For example, if the 'from' transform is "scale(2)" and the 'to'
transform is "none" then the value "scale(1)" will be used as the
'to' value, and animation will proceed using the rule above.
Similarly, if the 'from' transform is "none" and the 'to' transform
is "scale(2) rotate(50deg)" then the animation will execute as
if the 'from' value is "scale(1) rotate(0)".
</p>
<p>
The identity functions are translate(0),
translateX(0), translateY(0), scale(1),
scaleX(1), scaleY(1), rotate(0),
rotateX(0), rotateY(0), skewX(0), skewY(0),
and matrix(1, 0, 0, 1, 0, 0).
</p>
</li>
</ul>
</li>
<li>
If both the 'from' and 'to' transforms have the same number of
transform functions and corresponding functions in each transform
list are of the same type:
<ul>
<li>
Each transform function is animated with its corresponding
destination function in isolation using the rules described above.
The individual values are then applied as a list to produce
resulting transform value.
</li>
</ul>
</li>
<li>
Otherwise:
<ul>
<li>
The transform function lists are each converted into the
equivalent matrix value and animation proceeds using the rule
for a single function above.
</li>
</ul>
</li>
</ul>
