【问题描述】:
我要创建一个时间线组件,我有以下模板
<ul *ngIf="alerts!=undefined" class="timeline">
<li *ngFor="let alert of alerts; let i=index" [class.timeline-inverted]="i % 2 == 1">
<div class="timeline-badge">
<span>{{alert.type}}</span>
</div>
<div class="timeline-panel">
<div class="timeline-body">
<p>{{alert.id}}</p>
</div>
<div class="timeline-footer">
<p class="">{{alert.date}}</p>
</div>
</div>
</li>
</ul>
对应的.scss文件是这样的
.timeline {
list-style: none;
padding: 10px 0;
position: relative;
font-weight: 300;
border-style: solid;
border-width: medium;
}
.timeline:before {
top: 0;
bottom: 0;
position: absolute;
content:" ";
width: 6px;
background: $magenta;
left: 50%;
margin-left: -3px;
}
.timeline > li {
margin-bottom: 40px;
position: relative;
width: 50%;
float: left;
clear: left;
}
.timeline > li:before, .timeline > li:after {
content:" ";
display: table;
}
.timeline > li:after {
clear: both;
}
.timeline > li > .timeline-panel {
width: calc(100% - 35px);
width: -moz-calc(100% - 35px);
width: -webkit-calc(100% - 35px);
float: left;
border-radius: 5px;
background: $white;
position: relative;
}
.timeline > li > .timeline-panel:before {
position: absolute;
top: 26px;
right: -15px;
display: inline-block;
border-top: 15px solid transparent;
border-bottom: 15px solid transparent;
content:" ";
}
.timeline > li > .timeline-panel:after {
position: absolute;
top: 27px;
right: -14px;
display: inline-block;
border-top: 14px solid transparent;
border-left: 14px solid $white;
border-right: 0 solid $white;
border-bottom: 14px solid transparent;
content:" ";
}
<ul>标签没有被*ngFor创建的<li>标签填充,这使得时间线的“线”消失了。
黑色边框是<ul> 标签的边框,假设将所有<li> 标签包裹在其下方,并让洋红色线穿过所有气泡。
