android系统的开放性导致其终端的多样性，那么对于各种各样的android手机来说，屏幕分辨率的差异导致针对android手机的页面重构复杂性增加，那么我们可以用media query为每种分辨率提供特定样式：


 /* for 240 px width screen */
@media only screen and (max-device-width:240px){
    selector{
    }
}
 
/* for 360px width screen */
@media only screen and (min-device-width:241px) and (max-device-width:360px){
    selector{
    }
}
 
/* for 480 px width screen */
@media only screen (min-device-width:361px)and (max-device-width:480px){
    selector{
    }
}
