我想将 PNG 图像添加到我的导航栏。我找不到要添加到我的背景图像中的正确位置:并且它看起来是正确的。图像不以文本为中心，我需要它。谢谢

最佳答案
我想你想要这样的东西:
#navbar li ul table {
margin-top: -6px;
width: 350px;
background-image: url('http://i.stack.imgur.com/RuH5Q.png');
background-repeat: no-repeat;
background-size: 100% 100%;
border-radius: 15px;
}
#navbar li {
list-style: none;
float: left;
position: relative;
height: 50px;
line-height: 50px;
background-image: url('http://i.stack.imgur.com/RuH5Q.png');
background-repeat: no-repeat;
background-size: 100% 100%;
}
或者像这样，为下拉菜单中 table 元素的每个 td 保留背景:
#navbar li ul table td {
background-image: url('http://i.stack.imgur.com/RuH5Q.png');
background-repeat: no-repeat;
background-size: 100% 100%;
}
