CSS Transform - Element Scales BUT doesn't Translate

I have a video element inserted on my index.html page:

<body>
    <video id="animation" autoplay loop>
        <source src="animation.mp4" type="video/mp4">
        <source src="animation.webm" type="video/webm">
    </video>
    <script>
        scaletranslate();
    </script>
</body>

In my CSS sheet I am positioning the video simply:

body {
    margin: 0px;
    padding: 0px;
    overflow: hidden;
}
video {
    position: absolute;
    top: 0px;
    left: 0px;
}

And the Javascript's scaletranslate() function is:

document.getElementById("animation").style.transform = "translateX(250)";

The video does not move as it should, however, if I use this code:

document.getElementById("animation").style.transform = "scaleX(0.2)";

Then the video does get scaled.

Why is the element not being moved with the transform translate operation?

Solution

  • Add the pixel unit:

    translateX(250px)
