More Details for transform

transform

The transform CSS property lets you rotate, scale, skew, or translate an element. It modifies the coordinate space of the CSS visual formatting model.

If the property has a value different than none, a stacking context will be created. In that case, the element will act as a containing block for any position: fixed; or position: absolute; elements that it contains.

Warning: Only transformable elements can be transformed. That is, all elements whose layout is governed by the CSS box model except for: non-replaced inline boxes, table-column boxes, and table-column-group boxes.

Syntax

/* Keyword values */ transform: none;  /* Function values */ transform: matrix(1.0, 2.0, 3.0, 4.0, 5.0, 6.0); transform: matrix3d(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); transform: perspective(17px); transform: rotate(0.5turn); transform: rotate3d(1, 2.0, 3.0, 10deg); transform: rotateX(10deg); transform: rotateY(10deg); transform: rotateZ(10deg); transform: translate(12px, 50%); transform: translate3d(12px, 50%, 3em); transform: translateX(2em); transform: translateY(3in); transform: translateZ(2px); transform: scale(2, 0.5); transform: scale3d(2.5, 1.2, 0.3); transform: scaleX(2); transform: scaleY(0.5); transform: scaleZ(0.3); transform: skew(30deg, 20deg); transform: skewX(30deg); transform: skewY(1.07rad);  /* Multiple function values */ transform: translateX(10px) rotate(10deg) translateY(5px); transform: perspective(500px) translate(10px, 0, 20px) rotateY(3deg);  /* Global values */ transform: inherit; transform: initial; transform: revert; transform: unset; 

The transform property may be specified as either the keyword value none or as one or more <transform-function> values.

If perspective() is one of multiple function values, it must be listed first.

Values

<transform-function>

One or more of the CSS transform functions to be applied. The transform functions are multiplied in order from left to right, meaning that composite transforms are effectively applied in order from right to left.

none

Specifies that no transform should be applied.

Accessibility concerns

Scaling/zooming animations are problematic for accessibility, as they are a common trigger for certain types of migraine. If you need to include such animations on your website, you should provide a control to allow users to turn off animations, preferably site-wide.

Also, consider making use of the prefers-reduced-motion media feature — use it to write a media query that will turn off animations if the user has reduced animation specified in their system preferences.

"Olivia, my eldest daughter, caught measles when she was seven years old. As the illness took its usual course I can remember reading to her often in bed and not feeling particularly alarmed about it. Then one morning, when she was well on the road to recovery, I was sitting on her bed showing her how to fashion little animals out of coloured pipe-cleaners, and when it came to her turn to make one herself, I noticed that her fingers and her mind were not working together and she couldn’t do anything. 'Are you feeling all right?' I asked her. 'I feel all sleepy,' she said. In an hour, she was unconscious. In twelve hours she was dead. The measles had turned into a terrible thing called measles encephalitis and there was nothing the doctors could do to save her. That was...in 1962, but even now, if a child with measles happens to develop the same deadly reaction from measles as Olivia did, there would still be nothing the doctors could do to help her. On the other hand, there is today something that parents can do to make sure that this sort of tragedy does not happen to a child of theirs. They can insist that their child is immunised against measles. ...I dedicated two of my books to Olivia, the first was ‘James and the Giant Peach’. That was when she was still alive. The second was ‘The BFG’, dedicated to her memory after she had died from measles. You will see her name at the beginning of each of these books. And I know how happy she would be if only she could know that her death had helped to save a good deal of illness and death among other children."

I just checked google books for BFG, and the dedication is there.
