Answer 1

试试这个：

/* JS disabled styles */
.no-js nav li:hover ul 
{ 
    display:block; 
}

/* base nav styles */
nav 
{
    margin: 0 auto 20px;
    position: relative;
    background-color: #FFFFFF;
    font: 16px Tahoma, Sans-serif;
}

/*Temporaly Solution*/
nav ul a 
{ 
   border-bottom: thin; 
   border-bottom-style: solid;      
   border-bottom-color: transparent;
}
/*Solution Ended*/

nav ul 
{ 
    padding:0; 
    margin:0; 
}

nav li 
{ 
    position:relative; 
    float:left; 
    list-style-type:none; 
}

nav ul:after 
{ 
    content:"."; 
    display:block; 
    height:0; 
    clear:both; 
    visibility:hidden; 
}

nav ul a:hover, nav ul > li:hover > a 
{ 
    color: #F90; 
}

nav li a 
{
    display: block;
    padding: 10px 20px;
    color: #333;
    text-decoration: none;
    font-weight: 600;
}

nav li a:focus 
{ 
    outline:none; 
    text-decoration:underline; 
}

nav li:first-child a 
{ 
    border-left:none; 
}

nav li.last a 
{ 
    border-right:none; 
}

nav a span 
{ 
    display:block; 
    float:right; 
    margin-left:5px; 
}

nav ul ul 
{ 
    display:none; 
    width:110%; 
    position:absolute; 
    left:0; 
    background:#FFFFFF; 
}

nav ul ul li 
{ 
    float:none; 
}

nav ul ul a 
{ 
    padding:5px 10px; 
    border-left:none; 
    border-right:none; 
    font-size:14px; 
}

/* CSS3 */

    .cssgradients nav li:hover { background-image:-moz-linear-gradient(0% 100px 90deg, #999, #222); background-image:-webkit-gradient(linear, 0% 0%, 0% 100%, from(#222), to(#555)); }
    .borderradius nav ul ul { -moz-border-radius-bottomleft:4px; -moz-border-radius-bottomright:4px; -webkit-border-bottom-left-radius:4px; -webkit-border-bottom-right-radius:4px; border-bottom-left-radius:4px; border-bottom-right-radius:4px; }
    .boxshadow.rgba nav ul ul {
        background-color: rgba(255,255,255,0.8);
        -moz-box-shadow: 2px 2px 2px rgba(0,0,0,.8);
        -webkit-box-shadow: 2px 2px 2px rgba(0,0,0,.8);

    }
    .rgba nav ul ul li { border-left:1px solid rgba(0,0,0,0.1); border-right:1px solid rgba(0,0,0,0.1); }
    .rgba nav ul ul a:hover {

    .csstransforms ul a span { -moz-transform:rotate(-180deg);-webkit-transform:rotate(-180deg); }

希望有效。

Answer 2

您需要将:hover伪类分配给父li标记。

nav ul li:hover > a 
{ 
    color: #F90; 
}

Answer 3

这将为所有链接元素添加颜色。要仅添加到第一个链接元素，请替换：

nav ul a:hover 
{ 
    color: #F90; 
}

通过

nav ul a:hover, nav ul > li:hover > a 
{ 
    color: #F90; 
}

这种方式有效。已在当地尝试过。
