Question

I have a centered div and 4 other divs – one on each side of the centered div. When I click a button each of the div slide into the frame and push the centered div out.

It works fine in chrome but fails using firefox, leaving me with no error from firebug.

Here is my implementation which doesn’t currently work correctly in firefox.

As you can see, in firefox the centered div simply disappears instead of sliding out of the screen. Using chrome, the centered div slides out as intended.

Can someone take a look with firebug and tell me what they think might be causing the problem?

This code was based off of a jsfiddle that works fine using either chrome or firefox.

Here is the code to the jsfiddle:

here is the html

<div id="fullContainer">
    <div id="right">

    </div>
    <div id="left">

    </div>
    <div id="top">

    </div>
    <div id="bottom">

    </div>
</div>
<div id="centerContainer">
    <div id="relativeContainer">
        <div id="content">
            This is where your face should go.  Notice that I placed it within a centering div.  
            This will enable the face to be absolutely positioned, and allow for you to modify 
            it's position when the side-bars slide in.
            <div data-move="left">Open Left</div>
            <div data-move="right">Open Right</div>
            <div data-move="top">Open Top</div>
            <div data-move="bottom">Open Bottom</div>
        </div>
    </div>
</div>

here is the css

#centerContainer {
    position:fixed;
    top:50%;
    left:50%;
    width:0;
    height:0;
}
#relativeContainer {
    position:relative;
}
#fullContainer {
    position:fixed;
    width:100%;
    height:100%;
    top:0;
    left:0;
}
#content {
    position:absolute;
    width:300px;
    height:400px;
    top:-200px;
    left:-150px;
    background:#BADA55;
    border:1px solid #444;
    padding:10px;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}
#content.right {
    left:-250px;
}
#content.left {
    left:-50px;
}
#content.bottom {
    top:-300px;
}
#content.top {
    top:-100px;
}

#content div {
    cursor:pointer;
    color:blue;
    text-decoration:underline;
    margin-top:15px;
    text-align:center;
}
#left {
    position:absolute;
    top:0;
    left:-125px;
    height:100%;
    width:100px;
    background:blue;
    border:1px solid #444;
    padding:10px;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

#left.opened {
    left:0;
}

#right {
    position:absolute;
    top:0;
    right:-125px;
    height:100%;
    width:100px;
    background:green;
    border:1px solid #444;
    padding:10px;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

#right.opened {
    right:0;
}

#top {
    position:absolute;
    left:0;
    top:-125px;
    width:100%;
    height:100px;
    background:yellow;
    border:1px solid #444;
    padding:10px;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

#top.opened {
    top:0;
}

#bottom {
    position:absolute;
    left:0;
    bottom:-125px;
    width:100%;
    height:100px;
    background:red;
    border:1px solid #444;
    padding:10px;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

#bottom.opened {
    bottom:0;
}

here is the javascript:

function SlideOut(element){

    $(".opened").removeClass("opened");
    $("#"+element).addClass("opened");
    $("#content").removeClass().addClass(element);

}
$("#content div").click(function(){

    var move = $(this).attr('data-move');

    SlideOut(move);

});

Here is the fiddle

I did some testing and found out what’s happening. This is reproduced in this fiddle for illustration and demonstration purposes.

In Firefox if you are transitioning the CSS attribute left, it needs to have an initial value to start from. If it doesn’t then it won’t transition, it’ll just assign the value to the attribute.

In Chrome if you don’t have the initial value set it apparently just starts from wherever it is and doesn’t worry about it.

If you check out the above fiddle in Firefox and click on the first row, it just appears farther over, while the second row transitions over. Only difference is the second row has a left: 0 initially set. On Chrome both work the same.

If you put a left: 0 on your #content div then it will slide like it should in Firefox. (Tested in Firebug and that does fix it).
