表校准输入和下拉菜单

我怎么能对准我的输入框，以便第一个与标签一致，另外两个在顶部输入框下方排列。表校准输入和下拉菜单

为什么我的域和下拉菜单不对齐？

CSS：

#newwebsiteForm{ 
    padding:10px; 
    margin:10px 0; 
    width:480px; 
    position: relative 
} 
#newwebsiteForm label{ 
    display:block; 
    float:left; 
    clear:both; 
    margin:0 15px 0 25px; 
    width:240px; 
    border:1px solid green; 
    height:15px 
} 
#newwebsiteForm input{
