如何在 CSS 中的列表项后添加分隔符

Question

我正在尝试创建一个列表项并在它们之间添加分隔符我尝试了所有方法，但问题仍然存在。这是我希望我的列表菜单看起来像的图像：-

我使用的 css 和 html 代码是这样的：-

HTML :-

<p class="Categories">Categories</p>
<div class="Rectangle"></div>
<div class="Categories_Box box1 box2">
<ul>
<li><a href="#" class="">Today</a></li>
<div class="line1"></div>
<li><a href="#" class="yest">Yesterday</a></li>
<li><a href="#" class="this_week">This Week</a></li>
<li><a href="#" class="last_week">Last Week</a></li>
<li><a href="#" class="last_month">Last Month</a></li>
</ul>
</div>

CSS :-

   .Categories {
  font-size: 29px;
  font-family: "Exo";
  color: rgb(237, 106, 61);
  font-weight: bold;
  line-height: 0.869;
  position: absolute;
  left: 227.937px;
  top: 215px;
  z-index: 31;
}

.Rectangle {
  background-color: rgb(107, 107, 107);
  position: absolute;
  left: 231px;
  top: 281px;
  width: 194px;
  height: 5px;
  z-index: 29;
}


.Categories_Box ul{
 position:absolute;
 left: 0px;
 top: 0px;
 width: 1366px;
 height: 768px;
 z-index: 43;
 list-style:none;

}


.yest, .this_week, .last_week, .last_month {
  font-size: 21px;
  font-family: "Exo";
  text-decoration:none;
  color: rgb(107, 107, 107);
  font-weight: bold;
  line-height: 0.86;
  -moz-transform: matrix( 0.76907888849934,0,0,0.58955579248353,0,0);
  -webkit-transform: matrix( 0.76907888849934,0,0,0.58955579248353,0,0);
  -ms-transform: matrix( 0.76907888849934,0,0,0.58955579248353,0,0);
  position:relative;
  left: -175px;
  top: -641.112px;
  z-index: 30;
}

.line1 {
  font-size: 10px;
  font-family: "Arial";
  color: rgb(221, 221, 221);
  line-height: 4.2;
  position: absolute;
  left: 345.85px;
  top: 684.418px;
  z-index: 100;
}


.box2 {
  border-style: solid;
  border-width: 1px;
  border-color: rgb(217, 217, 217);
  border-radius: 5px;
  background-color: rgb(242, 242, 242);
  box-shadow: 0px 1px 2px 0px rgba(0, 0, 0, 0.36);
  position: absolute;
  left: 219px;
  top: 229px;
  width: 228px;
  height: 498px;
  z-index: 27;
}


.box1 {
  border-radius: 5px;
  background-color: rgb(255, 255, 255);
  position: absolute;
  left: 221px;
  top: 230px;
  width: 225px;
  height: 498px;
  z-index: 28;
}

编辑此代码后，我的前 20 个列表消失了，我什至看不到菜单项。 请帮帮我

Answer 1

您可以通过为列表项添加虚线边框来创建外观。举个简单的例子：

HTML：

<ul>
    <li><a href='#'>Title</a></li>
    <li><a href='#'>Element 1</a></li>
    <li><a href='#'>Element 2</a></li>
    <li><a href='#'>Element 3</a></li>
    <li><a href='#'>Element 4</a></li>
</ul>

CSS：

ul{
    list-style:none;
    padding-left:10px;
    padding-right:10px;
    width:140px;
    border:1px #eee solid;
    border-radius:10px;
}

li{
    border-bottom: 1px #ccc dashed;
}

a{
    padding-top: 10px;
    padding-bottom: 10px;
    color: rgb(107, 107, 107);
    text-decoration: none;
    width: 100%;
    height: 100%;
    display: inline-block;
}

li:last-child{
    border-bottom: none;
}

li:first-child{
    border-bottom: solid grey;
}
li:first-child a{
    color: rgb(237, 106, 61);
    font-weight: bold;
    font-size: 20px;
}

感谢您在经过大量尝试后回复我，我解决了我的问题。造成问题的是 z-index 属性。在以正确的顺序设置 z-index 属性后，我能够在列表项之间添加分隔符，而无需使用边框属性。这是代码：-

HTML :-

<p class="t20_files">Top 20 Files</p>
<div class="Rectangle1"></div>
<div class="Outside_box1 Inside_Box1">
<div class="Categories_Box1">
<ul>
<li><a href="#">Today</a></li>
<p class="line10">------------------------</p>
<li><a href="#">Yesterday</a></li>
<p class="line11">------------------------</p>
<li><a href="#">This Week</a></li>
<p class="line12">------------------------</p>
<li><a href="#">Last Week</a></li>
<p class="line13">------------------------</p>
<li><a href="#">This Month</a></li>
<p class="line14">------------------------</p>
<li><a href="#">Last Month</a></li>
</ul>
</div>
</div>

CSS:-

@import url(normalize.css);

html,body
{
    width: 100%;
    height: 100%;
    margin: 0px;
    padding: 0px;
    overflow-x: hidden; 
    background:url(../images/site_bg.png) no-repeat;
    position: relative;
    background-size: 100% 100%;
}
/*------------------------------Background---------------------------*/



/*-----------------------------Horizontal Menu Starts----------------*/
.head-menu {
  background:url(img/menu_bg.png);
  position: absolute;
  left: 219px;
  top: 117px;

  height: 81px;


    }

.head-menu ul {
     list-style: none;
     position:relative;

}

.head-menu li a {

    color: rgb(255, 255, 255);

如果您有任何其他方法可以只使用一行而不是在每个列表项之后使用 p 类标记，请发布它，以便我可以缩短我的代码。这是 JS Fiddle 链接：- JS Fiddle Link
