Bootstrap时间线修复

Question

我正在创建一个Bootstrap时间轴，它在移动或小屏幕设备上运行良好。但它在大屏幕设备中存在一些问题。请查看https://codepen.io/irshad437/pen/rLvxxa。并尝试调整窗口大小以检查其功能。它应该与移动设备相同。
请在codepen上查看。（在给定链接上）

Answer 1

您已计算.timeline-panel到767px分辨率的计算宽度。对于其他设备，宽度为46%。这就是为什么时间轴面板没有在图标旁边对齐的原因。

解决方案＃1

尝试为所有设备提供时间轴面板的计算宽度。因此，删除(min-width:767px)中的calc并将其添加到top声明。

ul.timeline > li > .timeline-panel {
    float: left;
    position: relative;
    width: 46%; // remove this or can be fallback
    padding: 30px 30px 20px 0px;
    width: calc(100% - 90px);
    width: -moz-calc(100% - 90px);
    width: -webkit-calc(100% - 90px);
 }

解决方案＃2

删除.timeline-panel中(min-width:767px)的宽度并更新顶部声明

@media(max-width:767px) {
    //remove
     /*ul.timeline > li > .timeline-panel {
        width: calc(100% - 90px);
        width: -moz-calc(100% - 90px);
        width: -webkit-calc(100% - 90px);
      } */ 
}

.timeline > li > .timeline-panel {
    float: left;
    position: relative;
    width: 100%;
    padding: 30px 30px 20px 100px;
}
