老师去除下划线问题

*{

margin: 0;

padding: 0;

}

.header{

width: 100%;

height: 80px;

background-color: #07cbc9;

position: relative;

}

.header .logo{

weight:200px;

position: absolute;

top: 10px;

left: 30px;

}

.header .nav ul li{

float: right;

list-style: none;

padding: 10px;

font-weight: bold;

color: white;

}

.header .nav{

position: absolute;

right: 20px;

top: 20px;

text-decoration: none;

}

老师这样下划线还是去不掉
