The CSS code has a lot of CSS3 elements and this form will only work in browsers that have support for CSS3 (which IE of course has not):

form.registration{
 width:600px;
 float:left;
 color:#818181;
 background: #f1f1f1 url(pen.png) no-repeat top right;
 border: 2px solid #ccc;
 padding:10px;
 font-family: Georgia;
 font-size: 14px;
 -moz-box-shadow: 0 1px 3px rgba(0,0,0,0.5);
 -webkit-box-shadow: 0 1px 3px rgba(0,0,0,0.5);
 -moz-border-radius: 15px;
 -webkit-border-radius: 15px;
}

The form will have rounded borders and a box shadow which looks very intriguing by using rgba values. Next, we define how the fieldset should be positioned:

form.registration fieldset{
  border-top:1px solid #ccc;
  border-left:0;
  border-bottom:0;
  border-right:0;
  padding:6px;
  margin:0px 30px 0px 0px;
}

The legend will give a name to the fieldset and we want it to have a less intense color:

form.registration legend{
  text-align:left;
  color:#ccc;
  font-size:18px;
  padding:0px 4px 0px 4px;
  margin-left:20px;
}

Now, let’s define the rest of the form:

form.registration label{
  font-size: 32px;
  width:200px;
  float: left;
  text-align: right;
  color:#999;
  clear:left;
  margin:4px 4px 0px 0px;
  padding:0px;
}
form.registration input{
  font-family: Georgia;
  font-size: 28px;
  float:left;
  width:300px;
  border:1px solid #cccccc;
  margin:2px 0px 2px 2px;
  color:#00abdf;
  height:32px;
  padding:3px;
  -moz-box-shadow: 0 1px 3px rgba(0,0,0,0.5);
  -webkit-box-shadow: 0 1px 3px rgba(0,0,0,0.5);
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
}
form.registration input:focus, form.registration select:focus{
  background-color:#E0E6FF;
}
form.registration select{
  font-family: Georgia;
  font-size: 28px;
  float:left;
  border:1px solid #cccccc;
  margin:2px 0px 2px 2px;
  color:#00abdf;
  height:40px;
  -moz-box-shadow: 0 1px 3px rgba(0,0,0,0.5);
  -webkit-box-shadow: 0 1px 3px rgba(0,0,0,0.5);
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
}

And now, let’t define some style for the CSS3 button:

.button, .button:visited{
  float:right;
  text-shadow: 0 -1px 1px rgba(0,0,0,0.25);
  border-bottom: 1px solid rgba(0,0,0,0.25);
  cursor: pointer;
  padding: 5px 10px 5px 5px;
  color: #fff;
  text-decoration: none;
  font-size: 32px;
  padding: 10px 15px;
  background-color: #00abdf;
  display: inline-block;
  -moz-border-radius: 10px;
 -webkit-border-radius: 10px;
 -moz-box-shadow: 0 1px 3px rgba(0,0,0,0.5);
 -webkit-box-shadow: 0 1px 3px rgba(0,0,0,0.5);
}
.button:hover{
  background-color: #777;
}

The html code looks as follows:

<form>
 <fieldset>
 <legend>About you</legend>
 <label>First name</label>
 <input type="text" maxlength="100" value=""/>           
 <label>Last name</label>
 <input type="text" maxlength="100" value=""/>                                  
 <label>Birthdate</label>
 <select>
 <option value="1">1</option>
 <option value="2">2</option>                             
 </select>
 <select>                               
 <option value="1">January</option>
 <option value="2">February</option>
 </select>
 <select>                           
 <option value="2009">2009</option>
 <option value="2008">2008</option>              
 </select>          
 </fieldset>
 <fieldset>
 <legend>Account details</legend>
 <label>E-Mail</label>
 <input type="text" maxlength="120" value=""/>
 <label>Password</label>
 <input type="password" maxlength="20"/>                                          
 </fieldset>
 <fieldset>   
 <a>Register</a>  
 </fieldset>   
</form>

Enjoy!
