html - 网格右侧不需要的额外边框

Question

我正在尝试为我的网格中的每张照片添加一个 border-right，这样它就会出现在两张照片之间，就像在图像上一样。但由于某种原因，页面右侧出现了一个不需要的大边框。不知道我怎样才能摆脱它。任何帮助将不胜感激。 https://jsfiddle.net/5a3t1hwx/

Answer 1

首先，捕获并修复您的 jsfiddle 中的错误。

1. 删除 HTML 文件中的所有 CSS 代码。使用分离的 CSS 代码。
2. 将右括号 ( } ) 添加到您的.item:hover。

然后，您的问题的解决方案:

1. 改变 position: fixed; 在你的所有.item:nth-child(x):after 到 position: absolute;
2. 将 position: relative; 添加到您的 .item
