CSS flexbox 水平时间轴

Question

我正在尝试制作一个 flexbox 水平时间轴

我有申请 :nth-child(2n) { transform: translateY(100%); } 的想法，但我遇到了很多问题来解决这个问题：

• 时间线之前的内容进入时间线（无法清除它们）
• 向父级添加overflow-x: auto; 也会自动添加overflow-y，如果您隐藏overflow-y，则只有一半时间线可见

还有另一种方法可以让 flexbox 成为可能吗？我也尝试了边距，但项目位置没有很好地居中

@import "compass/css3";

.flex-container {
  padding: 0;
  margin: 0;
  list-style: none;
  
  display: flex;
  
  /* This line make an undesired Y scrollbar */
  overflow-x: auto;
}

.flex-item {
  background: tomato;
  width: 200px;
  height: 150px;

  color: white;
  
  display: flex;
  align-self: flex-end;
  align-items: flex-end;
  justify-content: center;
}

.flex-item:nth-child(2n) {
  align-self: flex-end;
  align-items: flex-start;
  transform: translateY(100%);
}


/* Random heights for testing */
.flex-item:nth-child(5) {
  height: 100px;
}

.flex-item:nth-child(3) {
  height: 200px;
}

.flex-item:nth-child(4) {
  height: 100px;
}

.flex-item:nth-child(6) {
  height: 200px;
}

<div>
  <p>This text is ok, but there is an undesired Y scrollbar on the timeline</p>
</div>

<ul class="flex-container">
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
</ul>

<div>
  <p>This text should go after the timeline</p>
</div>

这是一个蹩脚但可行的解决方案;-)

将它作为第一个子元素添加到 flexbox（不过你应该整理一下）。

如果您希望position:absolute/relative 覆盖在时间线的顶部而不是之前，您可以使用它。

@import "compass/css3";
.flex-container {
  padding: 0;
  margin: 0;
  list-style: none;
  display: flex;
  /* Uncomment this line to see the issue */
  /*overflow-x: auto;*/
}

.flex-item {
  background: tomato;
  width: 200px;
  height: 150px;
  color: white;
  display: flex;
  align-self: flex-end;
  align-items: flex-end;
  justify-content: center;
}

.flex-item:nth-child(2n) {
  align-self: flex-end;
  align-items: flex-start;
  transform: translateY(100%);
}


/* Random heights for testing */

.flex-item:nth-child(5) {
  height: 100px;
}

.flex-item:nth-child(3) {
  height: 200px;
}

.flex-item:nth-child(4) {
  height: 100px;
}

.flex-item:nth-child(6) {
  height: 200px;
}

<ul class="flex-container">
  <div style="clear: both;">
    <p>This text should go before</p>
  </div>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
</ul>

Answer 2

由于您使用translateY 将您的项目向下移动，因此您需要相应地定位后面的所有内容

我刚刚在你的 div 中添加了一个 other_content 类，设置 position:relative和 top:200px

虽然您需要记住调整 top 值，这取决于您的项目有多大

.flex-item {
  background: tomato;
  width: 200px;
  height: 150px;

  color: white;
  
  display: flex;
  align-self: flex-end;
  align-items: flex-end;
  justify-content: center;
}

.flex-item:nth-child(2n) {
  align-self: flex-end;
  align-items: flex-start;
  transform: translateY(100%);
}


/* Random heights for testing */
.flex-item:nth-child(5) {
  height: 100px;
}

.flex-item:nth-child(3) {
  height: 200px;
}

.flex-item:nth-child(4) {
  height: 100px;
}

.flex-item:nth-child(6) {
  height: 200px;
}
.other_content{
  position:relative;
  top:200px;
}

<div>
  <p>This text is ok, but there is an undesired Y scrollbar on the timeline</p>
</div>

<ul class="flex-container">
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
  <li class="flex-item"><span>text</span></li>
</ul>

<div class="other_content">
  <p>This text should go after the timeline</p>
</div>
