I am playing with shapes in css and want to make a traditional bell shape (think Christmas bell). Here's the general shape that I'm going for (though I really don't care about the balls on the top and bottom):

Here's what I have so far:
http://jsfiddle.net/bhlaird/NeBtU/
#bell {
left:300px;
position: relative;
}
#bell:before, #bell:after {
position: absolute;
content: "";
left: 50px; top: 0;
width: 180px;
height:400px;
background: #d3d3d3;
border-radius: 150px 150px 150px 20px;
-webkit-transform: rotate(15deg);
-webkit-transform-origin: 0 0;
}
#bell:after {
left: 0;
-webkit-transform: rotate(-15deg);
-webkit-transform-origin:100% 0;
border-radius: 150px 150px 20px 150px;
}
But, I'm not sure how to get that curved look on the side and bottom. Any help would be appreciated.
EDIT: I've gotten closer by applying a radial-gradient to #bell:before and #bell:after. This gives me the curve on the side, now I just need the curve on the bottom. http://jsfiddle.net/NeBtU/2/
#bell {
left:300px;
position: relative;
}
#bell:before, #bell:after {
position: absolute;
content:"";
top: 0;
width: 180px;
height:400px;
background: #d3d3d3;
}
#bell:before {
left: 50px;
border-radius: 150px 150px 20px 30px;
-webkit-transform: rotate(15deg);
-webkit-transform-origin: 0 0;
transform: rotate(15deg);
transform-origin: 0 0;
background: radial-gradient(-50px 250px, 300px 1200px, transparent 20%, #d3d3d3 20%);
background: -webkit-radial-gradient(-50px 250px, 300px 1200px, transparent 20%, #d3d3d3 20%);
}
#bell:after {
left: 0;
-webkit-transform: rotate(-15deg);
-webkit-transform-origin:100% 0;
transform: rotate(-15deg);
transform-origin:100% 0;
border-radius: 150px 150px 30px 20px;
background: radial-gradient(230px 250px, 300px 1200px, transparent 20%, #d3d3d3 20%);
background: -webkit-radial-gradient(230px 250px, 300px 1200px, transparent 20%, #d3d3d3 20%);
}
Have a look at this one,

css
#bell {
left:300px;
top:20px;
position: relative;
}
#bell:before, #bell:after {
position: absolute;
line-height:0;
content:"\2315";
color:#d3d3d3;
font-size:100pt;
text-indent:30px;
top: 0;
width: 180px;
height:300px;
background: #d3d3d3;
}
#bell:before {
left: 50px;
border-radius: 150px 150px 20px 30px;
-webkit-transform: rotate(15deg);
-webkit-transform-origin: 0 0;
transform: rotate(15deg);
transform-origin: 0 0;
background: radial-gradient(-50px 250px, 300px 1200px, transparent 20%, #d3d3d3 20%);
background: -webkit-radial-gradient(-50px 250px, 300px 1200px, transparent 20%, #d3d3d3 20%);
}
#bell:after {
left: 0;
-webkit-transform: rotate(-15deg);
-webkit-transform-origin:100% 0;
transform: rotate(-15deg);
transform-origin:100% 0;
border-radius: 150px 150px 30px 20px;
background: radial-gradient(230px 250px, 300px 1200px, transparent 20%, #d3d3d3 20%);
background: -webkit-radial-gradient(230px 250px, 300px 1200px, transparent 20%, #d3d3d3 20%);
line-height:550px;
content:"\25CF";
color:#d3d3d3;
font-size:130pt;
text-indent:-15px;
}
ya its not exactly same as in the question, but came close.
EDITED

You can work out the size of your bell in Illustrator (I drew one for you), but here's your proof of concept, as a background-image
in CSS
.
I tryed to help you, with your way (Yes, It's hard!) and that the best I got:
#bell {
left:100px;
position: relative;
}
#bell:before, #bell:after {
position: absolute;
content: "";
left: 50px; top: 0;
width: 320px;
height:400px;
background: #d3d3d3;
border-radius: 150px 150px 150px 20px;
-webkit-transform: rotate(15deg);
-webkit-transform-origin: 0 0;
}
#bell:after {
left: 0;
-webkit-transform: rotate(-15deg);
-webkit-transform-origin:100% 0;
border-radius: 150px 150px 20px 150px;
line-height:740px;
content:"\25CF";
color:#d3d3d3;
font-size:200pt;
}
