Question

I’ve found a great example right here discussing how to animate specific corners of a border. However, it seems i get no change what so ever. After inserting an alert into the in and out functions i confirmed that they are fired. However, any change to the cornerization are just not there.

Has it to do with how i styled the divs?

div.menuItem {
    border-width: 5px 3px;
    border-style: solid;
    border-radius: 25px 45px 25px 45px;
    font: 30px Arial;
    font-weight: bold;
    padding: 15px;
    display: block;
    width: 200px;
    border-color: #00bb00;
    color: #fff;
    background-color:#8822cc;
    -webkit-text-stroke: 1px #000;
}

And here’s the script.

$('div.menuItem').hover(function () {
            alert("in");
    $(this).animate({
        "MozBorderRadiusTopleft": '50px',
        "MozBorderRadiusTopright": '50px'
    }, 900);
}, function () {
            alert("out");
    $(this).animate({
        "MozBorderRadiusTopleft": '25px',
        "MozBorderRadiusTopright": '25px'
    }, 900);
});

You could simply use a CSS transition:

div.menuItem {
    border-radius: 25px 45px 25px 45px;
    transition: border-radius .9s;
    /* all other properties... */
}
div.menuItem:hover {
    border-radius: 25px;
}

P.S. Don’t forget the vendor prefixes.
