我希望使用CSS在HTML页面上显示类似的内容:
我目前使用此代码:
.tree,
.tree ul {
margin:0 0 0 1em; /* indentation */
padding:0;
list-style:none;
color:#1f1f1f;
position:relative;
}
.tree ul {margin-left:.5em}
.tree:before,
.tree ul:before {
content:"";
display:block;
width:0;
position:absolute;
top:0;
bottom:0;
left:0;
border-left:1px solid;
}
.tree li {
margin:0;
padding:0 1.5em; /* indentation + .5em */
line-height:2em; /* default list item's `line-height` */
font-weight:bold;
position:relative;
}
.tree li:before {
content:"";
display:block;
width:10px; /* same with indentation */
height:0;
border-top:1px solid;
margin-top:-1px; /* border top width */
position:absolute;
top:1em; /* (line-height/2) */
left:0;
}
.tree li:last-child:before {
background:#fff; /* same with body background */
height:auto;
top:1em; /* (line-height/2) */
bottom:0;
}

<ul class="tree">
<li>Bad Credit/No Credit</li>
<li>Bankruptcy</li>
<li>Repossession</li>
<li>Consumer Proposal</li>
</ul>
&#13;
我怎么能这样做并且可能?

您可以使用:after
伪元素来保存点:
.tree li:after {
content: "\2022"; /* bullet code */
position: absolute;
left: 9px;
top: -1px;
}
.tree:after {
content: "\2022"; /* bullet code */
position: absolute;
left: -3px;
top: -8px;
}
.tree,
.tree ul {
margin:0 0 0 1em; /* indentation */
padding:0;
list-style:none;
color:#1f1f1f;
position:relative;
}
.tree ul {margin-left:.5em}
.tree:before,
.tree ul:before {
content:"";
display:block;
width:0;
position:absolute;
top:0;
bottom:0;
left:0;
border-left:1px solid;
}
.tree li {
margin:0;
padding:0 1.5em; /* indentation + .5em */
line-height:2em; /* default list item's `line-height` */
font-weight:bold;
position:relative;
}
.tree li:before {
content:"";
display:block;
width:10px; /* same with indentation */
height:0;
border-top:1px solid;
margin-top:-1px; /* border top width */
position:absolute;
top:1em; /* (line-height/2) */
left:0;
}
.tree li:last-child:before {
background:#fff; /* same with body background */
height:auto;
top:1em; /* (line-height/2) */
bottom:0;
}
.tree li:after {
content: "\2022"; /* bullet */
position: absolute;
left: 9px;
top: -1px;
}
.tree:after {
content: "\2022"; /* bullet */
position: absolute;
left: -3px;
top: -8px;
}

<ul class="tree">
<li>Bad Credit/No Credit</li>
<li>Bankruptcy</li>
<li>Repossession</li>
<li>Consumer Proposal</li>
</ul>
