我不明白为什么这些div的边距是重叠的.
.alignright {float: right}
#header .social {margin-top: 50px;}
#header .social a {display: inline-block;}
#header .social .fb {width: 64px; height: 1px; padding-top: 60px; overflow: hidden;}
#header .social .twit {width: 64px; height: 1px; padding-top: 60px; overflow: hidden;}
#header .contact {margin: 20px 70px 20px 0; font-size: 14px; font-weight: bold;}
#header .contact span {color: #FFFFFF;}
#header .search {margin: 10px 0 0;}<div class="alignright">
<div class="social">
<a href="#" class="twit"></a>
<a href="#" class="fb"></a>
</div><!-- social -->
<div class="contact">
Get in Touch: <span>+44 10012 12345</span>
</div><!-- contact -->
<div class="search">
<form method="post" action="">
<input type="text" value="" name="s" gtbfieldid="28">

</div>
