It's common to use multiple transforms at once. The 'transform' property can accept as many functions as needed, so you can use and combine them any way you want.

- It's common to use multiple transforms at once.
- For example:
transform: rotate(-5deg) scale(1.1); - Define only one transform declaration in a rule, otherwise the bottom-most declaration will override the transforms above.
The transform property can accept
as many functions as needed.
0:00
So you can use and
combine them anyway you want.

It's common to use multiple
transforms at once.
0:08
For example, you might want to rotate and
0:12
scale the size of an element
at the same time.
0:14
Earlier we applied a small rotation
to the top row of images on hover.
0:17
I really liked how that looked, so
I'm going to add the rotation back in.
0:23
So I'll go back to interactions.css.
0:27
And in my image hover rule here,
0:31
I'm going to replace the translate
function with the rotate function.
0:35
And I'll set the value to -5deg.
0:40
All right, so
let's make this transformation a little
0:46
more amusing by combining
rotate with a scale transform.
0:50
To do this I can simply add the scale
function anywhere in the transform value.
0:56
And it will apply it to the image at
the same time it applies the rotation.
1:01
So, right after the rotate function,
I'll add the scale function and
1:06
set the value to 1.1.
1:10
So the images now rotate negative
five degrees counterclockwise,
1:14
while they scale 1.1 times their size.
1:20
Now we can add more
transforms if we need them.
1:22
So for example, back in my hover
rule I'm going to add the translateY
1:25
function and
set the value to negative 20 pixels.
1:32
Once we hover over an image,
we can see that the images rotate,
1:39
scale, and
translate up all at the same time.
1:43
Keep in mind that you can only define
one transform declaration in a rule.
1:48
Otherwise, the bottom most declaration
will override everything above it.
1:53
And this is a common mistake developers
make when writing CSS transforms.
1:58
So, for example, later on I may want to
add a skew transformation to these images.
2:02
So instead of writing the skew function
here in the original list of values,
2:08
I might add it to the bottom
of the rule like this.
2:14
So now the only transform
we see applied is the skew.
2:24
Because the new transform declaration
overrides the one written above it.
2:29
Now, this is just a simple example.
2:36
A small mistake like this is pretty easy
to spot in one CSS rule, but sometimes you
2:38
may target the same element further down
in your CSS and try to apply a transform.
2:44
This is how you'd most likely
run into this problem.
2:50
So for instance, if I scroll all the way
down to the bottom of my style sheet and
2:52
say img:hover and apply the skew
transformation here in this rule,
2:58
once we refresh the browser
once again the rotate and
3:03
scale transforms are gone on hover,
they've been overwritten by the new rule.
3:07
Now, I really like the way the images
move when we combined rotate and scale.
3:20
So, I'm going to stick with these
two functions moving forward.
