How can I create simple spheres using CSS?

I didn’t love the answers and comments already provided; too much code for a simple sphere in html – css. You can simply do:

<div class = "sphere">Test</div>

The CSS:

body {
    background: #333;
    }

.sphere {
    width: 200px;
    height: 200px;
    line-height: 200px;
    text-align: center;
    color: #FFF;
    margin: 100px auto;
    /* The magic are those 2 lines: */
    border-radius: 100%;
    box-shadow: inset 0 0 80px #FFF;
    }

Then I wanted to challenge myself and so some more complex stuff. This is the result:

The HTML:

<div class = "sphere a">This</div>
<div class = "sphere b">Is</div>
<div class = "sphere c">A</div>
<div class = "sphere d">Test</div>

The CSS:

body {
    background: #333;
}
.sphere {
    width: 200px;
    height: 200px;
    line-height: 200px;
    text-align: center;
    position: absolute;
    margin: -100px;
    border-radius: 100%;
    box-shadow: inset 0 0 80px #FFF;
    color: #FFF;
}
.a {
    top: 10%;
    left: 20%;
}
.b {
    top: 30%;
    left: 60%;
}
.c {
    top: 60%;
    left: 40%;
}
.d {
    top: 80%;
    left: 70%;
}
