这是我的导航菜单的 CSS 代码：

#cssmenu *{
    z-index: 999
}
#cssmenu ul { margin: 0; padding: 0; text-align: center; }
#cssmenu li { margin: 0; padding: 0;}
#cssmenu a { margin: 0; padding: 0;}
#cssmenu ul {list-style: none;}
#cssmenu a {text-decoration: none;}
#cssmenu {
    height: 50px; 
    background-color: #74a5d4; /* main background color */
}
#cssmenu > ul > li {
    display: inline-block;
    margin-left: 15px;
    position: relative;
}
#cssmenu > ul > li > a {
    color: #FFFFFF; /* main link text color */
    font-size: 15px;
    line-height: 50px;
    padding: 16px 20px;
-webkit-transition: color .15s;
   -moz-transition: color .15s;
     -o-transition: color .15s;
        transition: color .15s;
}
#cssmenu > ul > li > a:hover {
    color: #ffffff; /* main link text hover color */
    background-color:#c3d021; /* main link background hover color */
}
#cssmenu > ul > li > ul {
    opacity: 0;
    visibility: hidden;
    padding: 16px 0 20px 0;
    background-color: #74a5d4; /*submenu link background color */
    text-align: left;
    position: absolute;
    top: 30px;
    left: 50%;
    margin-left: -90px;
    width: 180px;
-webkit-transition: all .3s .1s;
   -moz-transition: all .3s .1s;
     -o-transition: all .3s .1s;
        transition: all .3s .1s;
-webkit-border-radius: 5px;
   -moz-border-radius: 5px;
        border-radius: 5px;
-webkit-box-shadow: 0px 1px 3px rgba(0,0,0,.4);
   -moz-box-shadow: 0px 1px 3px rgba(0,0,0,.4);
        box-shadow: 0px 1px 3px rgba(0,0,0,.4);
}
#cssmenu > ul > li:hover > ul {
    opacity: 1;
    top: 50px;
    visibility: visible;
}
#cssmenu > ul > li > ul:before{
    content: '';
    display: block;
    border-color: transparent transparent rgb(250,250,250) transparent;
    border-style: solid;
    border-width: 10px;
    position: absolute;
    top: -20px;
    left: 50%;
    margin-left: -10px;
}
#cssmenu > ul ul > li { position: relative;}
#cssmenu ul ul a{
    color: #FFFFFF; /* submenu link text color */
    font-size: 13px;
    background-color: #74a5d4; /*submenu background color (behind links) */
    padding: 5px 8px 7px 16px;
    display: block;
-webkit-transition: background-color .1s;
   -moz-transition: background-color .1s;
     -o-transition: background-color .1s;
        transition: background-color .1s;
}
#cssmenu > ul > li:hover {
    background-color:#c3d021; /*background color that shows on the main menu link when hovering over the sub menu */
}
#cssmenu > ul > li:hover > a{
    color: #000000; /* main menu link hover text color */
}
#cssmenu ul ul ul {
    visibility: hidden;
    opacity: 0;
    position: absolute;
    top: -16px;
    left: 206px;
    background-color:#74a5d4;
    padding: 16px 0 20px 0;
    text-align: left;
    width: 160px;
-webkit-transition: all .3s;
   -moz-transition: all .3s;
     -o-transition: all .3s;
        transition: all .3s;
-webkit-border-radius: 5px;
   -moz-border-radius: 5px;
        border-radius: 5px;
-webkit-box-shadow: 0px 1px 3px rgba(0,0,0,.4);
   -moz-box-shadow: 0px 1px 3px rgba(0,0,0,.4);
        box-shadow: 0px 1px 3px rgba(0,0,0,.4);
}
#cssmenu ul ul > li:hover > ul { opacity: 1; left: 196px; visibility: visible;}
#cssmenu ul ul a:hover{
    background-color: #c3d021; /*submenu link hover color */
    color:#000000;
}
#cssmenu > ul > li.active {
    background-color:#c3d021;
    color:#000000;
}

底部的id：

#cssmenu > ul > li.active {
        background-color:#c3d021;
        color:#000000;
    }

当页面处于活动状态时创建活动/当前链接。它改变了链接的背景颜色，但不改变文本颜色。我究竟做错了什么？

这是活动链接的 HTML：

<li class="active"><a href="/home.php"><span>Homepage</span></a></li>

您需要将其应用于color本身<a>而不是<li>

#cssmenu > ul > li.active a {
color: black;
}

此外，对于：

#cssmenu *{
position: relative; 
z-index: 999
}

您忘记包含位置属性，因为z-index只能在具有相对或绝对/固定定位的元素上创建堆叠上下文 - 例外是 css3 flex items：

“Flex 项目的绘制与内联块 [CSS21] 完全相同，除了使用 'order' 修改的文档顺序代替原始文档顺序，并且 'auto' 以外的 'z-index' 值创建堆叠上下文，即使'位置'是'静态的'。”

而是尝试：

a:link {
    //your styles
}a:visited {
    //your styles
}a:hover {
    //your styles
}a:hover {
    //your styles
}

并确保订单得到维护......
