宽度100％导致水平滚动条

时间：2018-04-20 20:06:04

标签： html css

我创建了一个包含HTML和CSS的页面，问题是水平滚动条显示，尽管我已经检查过没有宽度超过100％的元素或不适当的填充或边距。

这是完整的HTML和CSS代码：https://jsfiddle.net/m11nsbag/9/

html,
body {

  padding: 0;

我认为可能有一个填充物或边缘，我正在忽略，但我已经看了好几个小时，几乎尝试了任何东西。

感谢您的真诚帮助。

更新：我用100％更改了所有100vw，问题得到解决。

答案 0 :(得分：0)

vw单位中包含垂直滚动条 因此，当有垂直滚动条时，100vw比视口宽（没有滚动条）。

一个建议是将#modalcontainer更改为width:100%而不是width:100vw。
