javascript - div重叠另一个虽然div的位置是相对的

Question

我有一个使用 d3.js 制作的图表:code for chart

我正在尝试将此图表放在网站中。 website

问题是一个 div 溢出另一个，如网站所示。 我尝试将图表的位置从绝对位置更改为相对位置。它不起作用。

可能是什么问题。为什么会这样？任何想法。

与网站相关的 fiddle :My code so far (在这里做实验)

网站中使用的图表的 css 和 d3 javascript 代码(以上 fiddle 链接中的所有内容均可用):

Answer 1

从图表包装器中完全删除位置 css 属性

.chart-wrapper {
  width: 100%;
  height: 100%;
  background-color: #0d0d0d;
}

并编辑 chart-wrapper 的父级并添加自定义高度。您可以调整高度以使其正确适合。

<div class="container" style="height:700px;">

我通过 Chrome 开发工具 CSS 管理器在您的网站上进行了相同的测试。它不再重叠并正确放置。
