转到http://planetminecraft.com，当您查看链接时，您可以看到它们在连接受众的页面上时保持着色。保持a：人在页面上时处于活动状态？
我想做同样的事情，但黑色背景不影子。这是我的HTML和CSS

html, body {
height: 100%;
margin: 0;
background: #A3A3A3;
background-image: linear-gradient(180deg, #7D7D7D, #7D7D7D 50px, transparent 57px, transparent 140%);

#maincontainer {
min-height: 100%;
width: 960px;
min-width: 600px;
margin: auto;
border: ridge;
border-color: #919191;
border-top: 0;
border-bottom: 0;
background: rgba(255,255,255,0.35);
padding-left: 16px;
padding-right: 16px;
}
ul {
list-style-type:none;
margin:0;
padding:0;
overflow:hidden;
padding-top: 6px;
}
li {
float:left;
margin-right: 12px;
border: groove;
border-width: 2px;
border-color: #969696;
}
a {
display:block;
padding-left: 5px;
padding-right: 5px;
height: 38px;
background-color:#7D7D7D;
text-align: center;
text-decoration: none;
line-height: 37px;
color: #EDEDED;
font-weight: bold;
font-family: impact;
font-size: 1.8em;
}
li:hover {
float:left;
margin-right: 12px;
border: ridge;
border-width: 2px;
border-color: #969696;
}
a:hover {
color: white;
}
a:active {
background-color: black;
}
你只需要看看一个a:hover a:active li li:hover ul
而且这可能与CSS还是需要的JavaScript。
