Transform isn't working with jQuery .animate()

I noticed that whenever I try to use transform with a jQuery animation in the css section, it doesn't go off. It is the only property not working for me.
I am trying to use:
$(myElement).animate({
opacity: 1,
transform: "scale(1.5)"
}, 7000);
But the above code only passes the opacity animation, ignoring the transform.

One solution would be to use css for the animation and jquery to add the class that does the animation.
$(myElement).addClass("animate");
.animate {
transition: all 7s;
transform: scale(1.5);
}

Using the .animate() function, this would work.
$(myElement).animate({
height: ($(this).height()*1.5),
width: ($(this).width()*1.5)
}, 7000);

Car driving forward animation using JavaScript/CSS3 for banner advertisement

Is there a way to use JavaScript or CSS3 to animate an image of a car driving towards a user? To clarify, the car image should animate from the background, with the image smaller and seemingly further away and gradually get larger as it "drives" forward to the foreground of the image? The image will be of the front part of the car and will look like this:
This JavaScript animation will be utilized in an HTML5 banner advertisement so I am hoping to avoid anything that will increase the size of my deliverable substantially. I have been looking online for something similar to this and can't seem to find an example of what I am hoping to accomplish. Any ideas are welcome.

You don't need javascript, you can just use a CSS3 animation. For example, this would work:
#keyframes drive {
from {
transform: scale(0.2);
}
to {
transform: scale(1);
}
}
.car {
animation: drive 3s cubic-bezier(0.02, 0.01, 0.21, 1) infinite;
}
<img class="car" src="https://i.stack.imgur.com/oT3DY.png"/>
Explanation:
First, we define a drive animation. It starts with a CSS3 transform that scales the image to 1/5th the size, then at the end of the animation, to full size. You can use any css property, even width but transform: scale doesn't force a page render, so your animation is faster.
Then, let's break down the animation property on the .car.
drive - this part is self-explanitory, it tells CSS to use the drive key frames
3s - makes the animation last 3 seconds
cubic-bezier(0.02, 0.01, 0.21, 1) - sets the curve for the animation to run, so it scales slower the further along it goes.
infinite causes the animation to repeat infinitely.

This should get you started:
img {
-webkit-animation:mymove 5s infinite; /*Safari and Chrome*/
animation:mymove 3s infinite;
position: relative;
}
#keyframes mymove
{
0% {width:10%;}
10% {width:20%;}
20% {width:30%;}
30% {width:40%;}
40% {width:50%;}
50% {width:60%;}
60% {width:70%;}
70% {width:80%;}
80% {width:90%;}
90% {width:100%;}
100% {width:100%;}
}

background transition fix and background dim on hover [fiddle inside]

I got completely stuck on this. I have a container with background image. Inside the container are 3 little circles. What I am trying to do is to zoom the background image when I hover over it and dim the background image when I hover over any of the 3 little circles.
I got to the point where the 3 circles are properly overlapping the container and the background zooms in on hover. But I have 2 issues
no. 1 I am not very fond of the way I am achieving the overlay of the circles, which is this code
#circle_wrap{
position: absolute;
margin-top: -130px;
}
no. 2 Is that I have no clue how to dim the background. My original intention was to have a hidden black conteniner with 0.5 opacity that would be displayed when I hover over one of the circles. But I couldn't figure out how to select the overlay.
JSFIDDLE here
If anything couldn't be solved with css only, I'd accept jquery solution as well.
I'm looking for any advice/tips/solutions you guys have, I really need to get this working.
Thank you.

Finally got so angry I am not able to do it with css that I made it with jquery :(
If anyone is interested here is the result
I have at least fixed the issue no1 with better css but the second is done with jquery.
solved no.1 with
.circle_wrap{
position: absolute; bottom: 0; width: 100%; height: 100px;
}
and applying position:relative on its parent
and the solution for no.2 is
$(".circle_wrap").hover(function () {
$(this).siblings("img").css("opacity", "0.2");
},
function () {
$(this).siblings("img").css("opacity", "1");
});
EDIT: safari support
.wrap img:hover{
-moz-transition: scale(1.1) rotate(0deg);
transform: scale(1.1) rotate(0deg);
-webkit-animation-name: scaleThis;
-webkit-animation-duration:5s;
-webkit-animation-iteration-count: 1;
-webkit-animation-timing-function:ease-in-out;
}
#-webkit-keyframes scaleThis {
0% { -webkit-transform:scale(1) rotate(0deg); }
10% { -webkit-transform:scale(1.1) rotate(0deg); }
100% {-webkit-transform:scale(1.1) rotate(0deg); }
}

How to zoom in to the center of a div

I want to create a zoom in effect on my large div. I have searched many questions and still don't know how this work.
I want to be able to zoom into the center of the user screen instead of the set position.
http://jsfiddle.net/kB27M/1/
I have tried css3 zoom feature and animate zoom property but still can't pull this one. Can anyone help me about it? Thanks a lot!

You should scale the div:
.scaled {
-moz-transform: scale(3);
-webkit-transform: scale(3);
-ms-transform: scale(3);
transform: scale(3);
}
div {
transition: all 500ms ease-in;
}
Simply apply the CSS class to the div and then use the transitionEndevent to apply further styles via .animate().
On transitionEnd (discard live(), use on()): jsfiddle

How do I invoke a CSS3 transition using JavaScript?

When I click on a button, I want a div to rotate, just as I would do with a CSS3 transition: rotate(350deg);. How would I do this with either CSS or JS? (If it can be done with CSS I'd perfer that instead)

In the onclick event of the button, put:
document.getElementById("yourDivId").className += " rotate";
In the CSS:
#yourDivId {
transition: transform 1s;
}
.rotate {
transform: rotate(360deg);
}
You'd have to add the browser specfic prefixes (-moz-, -webkit-) to the transition and transform, but this should work for you.
