Internet explorer and Firefox use the standard extension rather than the webkit extension for animation. You need to add the standard css as well as the webkit vendor extension which would change your css to:
#loading {
margin: 80px auto;
position: relative;
width: 100px;
height: 100px;
-webkit-border-radius: 50px;
-moz-border-radius: 50px;
border-radius: 50px;
background: #ccc;
font: 12px "Lucida Grande", Sans-Serif;
text-align: center;
line-height: 100px;
color: white;
-webkit-box-shadow: 0 0 5px rgba(0,0,0,0.5);
-moz-box-shadow: 0 0 5px rgba(0,0,0,0.5);
box-shadow: 0 0 5px rgba(0,0,0,0.5);
}
#loading:before {
content: "";
position: absolute;
left: -20px;
top: -20px;
bottom: -20px;
right: -20px;
-webkit-border-radius: 70px;
-moz-border-radius: 70px;
border-radius: 70px;
background: #eee;
z-index: -2;
-webkit-box-shadow: inset 0 0 10px rgba(0,0,0,0.2);
-moz-box-shadow: inset 0 0 10px rgba(0,0,0,0.2);
box-shadow: inset 0 0 10px rgba(0,0,0,0.2);
}
#loading span {
position: absolute;
width: 0;
height: 0;
border-left: 50px solid transparent;
border-right: 50px solid transparent;
border-top: 80px solid rgba(255,255,255,0.7);
z-index: -1;
top: -28px;
left: 0px;
-webkit-animation: ticktock 5s linear infinite;
-webkit-transform-origin: 50px 80px;
animation: ticktock 5s linear infinite;
transform-origin: 50px 80px;
}
#loading strong {
overflow: hidden;
display: block;
margin: 0 auto;
-webkit-animation: expand 2.5s linear infinite;
animation: expand 2.5s linear infinite;
}
@-webkit-keyframes expand {
0% {
width: 0;
}
100% {
width: 60px;
}
}
@-webkit-keyframes ticktock {
0% {
-webkit-transform: rotate(0);
}
100% {
-webkit-transform: rotate(360deg);
}
}
@keyframes expand {
0% {
width: 0;
}
100% {
width: 60px;
}
}
@keyframes ticktock {
0% {
transform: rotate(0);
}
100% {
transform: rotate(360deg);
}
}
This should allow your css to load on most modern browsers. However depending on what users you will be attracting it may be worth implementing other vendor extensions such as -moz- or -o-.
For information about which extensions to use there are sites that tell you which browser versions support which extensions.
