    <thetext>http://www.w3.org/TR/2013/WD-css-transforms-1-20131126/#transform-rendering
states in Example 4:


|  transform: translate(80px, 80px) scale(1.5, 1.5) rotate(45deg);
| }
|
| This transform moves the element by 80 pixels in both the X and Y directions,
| then scales the element by 150%, then rotates it 45° clockwise about the Z axis. 

This is technically incorrect. It should read

&quot;This transform rotates the element 45° clockwise about the Z axis, then scales the element by 150%, then moves it by 80 pixels in both the X and Y directions.&quot;

And further:

| Note that the scale and rotation operate about the center of the element,
| since the element has the default transform-origin of 50% 50%.

This is very misleading in this context, since it implies that the translation affects the transform-origin too, which it doesn&apos;t.


Similar issue in http://www.w3.org/TR/2013/WD-css-transforms-1-20131126/#transform-function-lists :
| [...] a nested set of transforms is equivalent to a single list of transform functions,
| applied from the outside in.

I&apos;m not sure what that even means. Would &quot;applied from the inside out&quot; be more appropriate?
Mathematically, we&apos;re talking about the fact that for all x, we have (f o g)(x) == f(g(x)). Now, are we applying f and g &quot;from the inside out&quot; or &quot;from the outside in&quot;? Or is there a better way to put it? I feel like there should be.</thetext>
