如何像css sprite一样并排对齐图像
<style>
.a, .mail-green, .star{ display: block; background: url('http://css.spritegen.com//uploads/ka3dublic7f3p1363fcj1lpei1.png') no-repeat; }
.a { background-position: -0px -0px; width: 103px; height: 30px; }
.mail-green { background-position: -0px -30px; width: 159px; height: 30px; }
.star { background-position: -0px -60px; width: 198px; height: 28px; }
</style>
<div class="a"/>
<div class="main-green"/>
<div class="star"/>
