CSS - 无序列表中项目符号之间的垂直线

Question

我如何在无序列表中绘制子弹之间的垂直线,如下所示:

请注意,该行在最后一个列表项目符号处停止.我正在使用list-style:none;和图像作为子弹.HTML看起来像这样:

<ul class="experiences">

  <!-- Experience -->
  <li class="green">
    <div class="where">New York Times</div>
    <h3 class="what green">Senior Online Editor</h3>
    <div class="when">2012 - Present</div>

    <p class="description">Jelly-o pie chocolate cake...</p>
   </li>

   ...

要求的CSS代码:

/* Experiences */
ul.experiences {
    padding-left: 15px;
    margin-top: -1px;
}
ul.experiences li {
    padding-left: 33px;
    margin-bottom: 2.5em;
    list-style: none;
    background: url('../img/misc/list-bullet-darkgray.png') no-repeat;
}
ul.experiences li.green {
    background: url('../img/misc/list-bullet-green.png') no-repeat;
}
ul.experiences li.blue {
    background: url('../img/misc/list-bullet-blue.png') no-repeat;
}
ul.experiences li.pink {
    background: url('../img/misc/list-bullet-pink.png') no-repeat;
}
.where {
    font-size: 1.2857em; /* 18/16 -> 18px */
    font-weight: 300;
    display: inline;
    margin-right: 0.5em;
}
.what {
    font-size: 0.75em; /* 12/16 -> 12px */
    font-weight: 700;
    text-transform: uppercase;
    color: #fff;
    background-color: #444444;
    display: inline-block;
    padding: 0 12px;
    margin: -5px 0.5em 0 0 !important;
    -webkit-border-radius: 3px;
    -moz-border-radius: 3px;
    border-radius: 3px;
}
.what.green {
    background-color: #c4df9b;
}
.what.blue {
    background-color: #6dcff6;
}
.what.pink {
    background-color: #f06eaa;
}
.when {
    float: right;
    color: #b9b9b9;
    font-style: italic;
}
.description {
    display: block;
    margin-top: 0.5em;
}

Answer 1

我怀疑这是否可以通过边界和"摆弄利润"来实现,正如其他人所暗示的那样,至少我没有运气这样做.

此解决方案使用CSS生成的内容(:before和:after)来绘制项目符号和行.它允许高度自定义并保持标记清洁,但请注意浏览器支持.

JSFiddle(滚动CSS直到/* BORDERS AND BULLETS */评论)

ul.experiences li {
    position:relative; /* so that pseudoelements are positioned relatively to their "li"s*/
    /* use padding-bottom instead of margin-bottom.*/ 
    margin-bottom: 0; /* This overrides previously specified margin-bottom */
    padding-bottom: 2.5em;
}

ul.experiences li:after {
    /* bullets */
    content: url('http://upload.wikimedia.org/wikipedia/commons/thumb/3/30/RedDisc.svg/20px-RedDisc.svg.png');
    position: absolute;
    left: -26px; /*adjust manually*/
    top: 0px;
}

ul.experiences li:before {
    /* lines */
    content:"";
    position: absolute;
    left: -16px; /* adjust manually */
    border-left: 1px solid black;
    height: 100%;
    width: 1px;
}

ul.experiences li:first-child:before {
   /* first li's line */
   top: 6px; /* moves the line down so that it disappears under the bullet. Adjust manually */
}

ul.experiences li:last-child:before {
    /* last li's line */
   height: 6px; /* shorten the line so it goes only up to the bullet. Is equal to first-child:before's top */
}

注意:如果行的border-color指定了alpha通道,则第一个和第二个元素的边界之间的重叠将是显而易见的.

由于这里没有太多好的答案，我想我应该添加我的解决方案：

我利用相对位置，并在最后一项上添加白色遮罩以隐藏溢出。适用于移动视图和项目高度的变化。

超文本标记语言

<div class="list-wrapper">

    <div class="red-line"></div>

    <div class="list-item-wrapper">
        <div class="list-bullet">1</div>
        <div class="list-item">
            <div class="list-title">ITEM</div>
            <div class="list-text">Text</div>
        </div>
    </div>

    <div class="list-item-wrapper">
        <div class="list-bullet">2</div>
        <div class="list-item">
            <div class="list-title">ITEM</div>
            <div class="list-text">Text</div>
        </div>
    </div>

    <div class="list-item-wrapper">
        <div class="list-bullet">3</div>
        <div class="list-item">
            <div class="list-title">ITEM</div>
            <div class="list-text">Text</div>
        </div>
        <div class="white-line"></div>
    </div>

</div>

CSS

.list-wrapper {
  position:relative;

.list-item-wrapper {
  margin-top:10px;

  float:left;
