CSS Animation Not Working In All Browsers

I am having trouble getting any browser apart from Firefox to animate the JSFiddle below.. I think i have added all options for browsers but somethings not right :(( FIREFOX 27:

Solution 1:

Demo

You aren't using the browser specific syntax for the properties.

You do:

@-webkit-keyframes slidein {
    from {
        transform:translateX(0);
    }
    to {
        transform:translateX(calc(-100% + 250px));
    }
}

It should be this, note that I use the -webkit-transform before transform:

@-webkit-keyframes slidein {
    from {
        -webkit-transform:translateX(0);
    }
    to {
        -webkit-transform:translateX(calc(-100% + 250px));
    }
}
