page-break-inside:避免和块级元素在Chrome中创建空列

Question

在这个名为https://jsfiddle.net/rpep00dg/7/的小提琴中，Chrome中的内容以一个空列作为前缀。如果您在Firefox或Safari中打开小提琴，则在"Header“之前没有空列。如果第一个元素是任何块级元素，比如p标记，情况似乎就是这样。

这是不是任何地方都有文档记录的Chrome bug？还有，有没有什么变通办法，让它像Firefox和Safari一样渲染？

​

section {
  page-break-inside: avoid;
  margin-bottom: 10px;
}

html {
  height: 100%;
}

body {
  column-count: 2;
  column-gap: 36px;
  width:100%;
  height: 100%;
  column-fill: auto;
}

<section>
<h1>Header</h1>

Answer 1

这里有几个问题：

您忘记在标题h1标记中关闭section。关闭它，它将在chrome中工作得很好。

Second:

对于特定的浏览器，请考虑以下内容：

-webkit-column-count: 2; /* Chrome, Safari, Opera */
-moz-column-count: 2; /* Firefox */
 column-count: 2; /*Default

我测试了上面的代码，它像预期的那样工作。

希望能有所帮助。
