Question

我的页面左侧有一个垂直菜单div，有6个链接，底部有一个图像。链接的样式是盒子。我希望能够使用JS来更改链接框的边距，使它们填充高度，但不会因较小的分辨率而消失。这是我试图没有效果的。

这是css

.sidebar {
    float: left;
    background-color:#FFFFFF;
    background-image: url('../images/sandMenu1.jpg');
    width: 150px;
    min-height: 100vh;
    color: #04B4AE;
    margin-top: 50px;
    background-size:  100%;
    background-repeat: no-repeat;
    background-position: left top;
    z-index: 1;
    padding-top: 35px;
    position: fixed;
}

#sidebarLink a:link, a:visited{
   display: inline-block;
   font-weight: bold;
   background-color: #D7F5BA;
   color: #04B4AE;  
   width: 90px;
   padding: 4px;
   border-style: outset;
   border-width: 2px;
   border-color: #D8D8D8;
   margin-top: 35px;
   margin-bottom: 35px;
   margin-right: 30px;
   float: right;
}


#sidebarLink a:hover, a:active, a:focus{
   font-weight: bold;
   background-color: #B404AE;
   color: #04B4AE;  
   width: 90px;
   padding: 4px;
   border-style: outset;
   border-width: 2px;
   border-color: #6A0888;
   margin-top: 35px;
   margin-bottom: 35px;
   margin-left: 15px;
   margin-right: 30px;
   float: right;
}   

.sidebarLinkList li {
   list-style-type: none;
   margin: 0;
   padding: 0;
}

这是HTML。

  <div id="sideMenu" class="sidebar">
<nav id="sidebarLink">
  <ul class="sidebarLinkList">
    <li><a href="home.html">Home</a></li>
    <li><a href="about.html">About Us</a></li>
    <li><a href="link.html">link</a></li>
    <li><a href="Destination.html">Destination</a></li>
    <li><a href="homepage.html">Home</a></li>
    <li><a href="homepage.html">Home</a></li>
  </ul>
</nav>
<div>
  <img src="images/sand.jpg" class="sand" id="sidePic">
</div>
  </div>

 <script>
   var winHeight = $(window).height();
   var winWid = $(window).width();
   var spacing = 0;
   var menuHeight = 0;
   menuHeight = (winHeight - 280); /*header height+image height+image margin = 280px*/
   spacing = (menuHeight - (6 * 25))/12; /*links are ~25px tall*/
   document.getElementById("sidebarLink").style.marginTop=spacing+"px";
   document.getElementById("sidebarLink").style.marginBottom=spacing+"px";
  </script>

我对任何建议持开放态度，我没有开始使用Javascript来执行此操作。谢谢。

您可以使用css高度百分比来完成所有这些操作。您可以使用css3 calc计算图像上方菜单的高度，并为li元素提供16％的高度，以均匀地填充菜单：
