有一个flexbox网格。

.flex {
  display: flex;
  flex-wrap: wrap;
  border: 2px solid red;
}

.item {
  width: 50px;
  height: 50px;
  margin: 5px;
  border: 2px solid blue;
}

<div class="flex">
  <div class="item"></div>
  <div class="item"></div>
  <div class="item new-string"></div>
</div>

如何将.new-string及其后续元素转移到新行？

最佳答案

如果查看this great answer，您会注意到，唯一的跨浏览器方式(没有2个换行符限制)是插入100% -width空块(“换行符”)。因此，对于类似的标记，它看起来像

.flex {
  display: flex;
  flex-wrap: wrap;
  border: 2px solid red;
}

.item {
  width: 50px;
  height: 50px;
  margin: 5px;
  border: 2px solid blue;
}

.line-break {
  width: 100%;
}

<div class="flex">
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="line-break"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="line-break"></div>
  <div class="item"></div>
  <div class="line-break"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
</div>

如果要保留标记样式，则必须通过JavaScript插入以下line-break块:

var items = document.querySelectorAll(".flex > .item.new-string");

for (var i = 0; i < items.length; i++) {
  var lineBreak = document.createElement('div');
  lineBreak.className = "line-break";

  items[i].parentNode.insertBefore(lineBreak, items[i]);
}

.flex {
  display: flex;
  flex-wrap: wrap;
  border: 2px solid red;
}

.item {
  width: 50px;
  height: 50px;
  margin: 5px;
  border: 2px solid blue;
}

.line-break {
  width: 100%;
}

<div class="flex">
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item new-string"></div>
  <div class="item"></div>
  <div class="item new-string"></div>
  <div class="item new-string"></div>
  <div class="item"></div>
  <div class="item"></div>
</div>
