<div id="container">
<p class="separator"><br/></p>
<p class="small-title">Too Plain</p>
<input class="too-plain" value="Enter your email here" />
<p class="separator"><br/></p>
<p class="small-title">Fading The Label</p>
<form>
<label class="username-label" for="username">Username</label>
<input type="text" name="username" class="username" />
<label class="password-label" for="password">Password</label>
<input type="password" name="password" class="password" />

<p class="separator"><br/></p>
<p class="small-title">Sliding? Don't Worry</p>
<form>
<label class="username-label-sliding" for="username-sliding">Username</label>
<input type="text" name="username" class="username-sliding" />
<label class="password-label-sliding" for="password-sliding">Password</label>
<input type="password" name="password" class="password-sliding" />
</form>
<p class="separator"><br/></p>
</div>
css代码如下：
* {

text-align:center;
font-family:Georgia, "Times New Roman", Times, serif;
font-size:13px;
line-height:1.5em;
margin-top:8%;

border:5px solid #e0e0e0;
-webkit-border-radius:20px;
border-radius:20px;
-moz-border-radius:20px;
}
input:focus {

#container {

width:700px;
margin-left:auto;
margin-right:auto;
}
.separator {

jQuery代码如下：
$(document).ready(function(){
$('.too-plain').focus(function(){
if($(this).val()=="Enter your email here")
{$(this).val("");}
}).blur(function(){
if($(this).val()=="")
{
$(this).val('Enter your email here');
}
});
$(".username-label,.password-label").animate({ opacity: "0.4" }).click(function(){
var thisFor=$(this).attr("for");
$('.'+thisFor).focus();
})
$(".username").focus(function(){
$(".username-label").animate({opacity:"0"},"fast");
if($(this).val()=="username")
{
$(this).val()=="";
}
}).blur(function(){
if($(this).val()=="")
{
$(this).val()=="username";
$(".username-label").animate({opacity:"0.4"},"fast");
}
})
$('.password').focus(function(){
$(".password-label").animate({opacity:"0"},"fast");
if($(this).val()=="password"){
$(this).val()=="";
}
}).blur(function(){
if($(this).val()=="")
{
$(this).val()=="password";
$('.password-label').animate({opacity:"0.4"},"fast");
}
});
$('.username-label-sliding,.password-label-sliding').animate({opacity:"0.4"}).click(function(){
var thisFor=$(this).attr('for')
$('.'+thisFor).focus();
})
$('.username-sliding').focus(function() {
$('.username-label-sliding').animate({ marginLeft: "7em" }, "fast");
if($(this).val() == "username")
$(this).val() == "";
}).blur(function() {
if($(this).val() == "") {
$(this).val() == "username";
$('.username-label-sliding').animate({ marginLeft: "12px" }, "fast");
}
});
$('.password-sliding').focus(function() {
$('.password-label-sliding').animate({ marginLeft: "7em" }, "fast");
if($(this).val() == "password") {
$(this).val() == "";
}
}).blur(function() {
if($(this).val() == "") {
$(this).val() == "password";
$('.password-label-sliding').animate({ marginLeft: "12px" }, "fast");
}
});
})
