html5 css 右侧额外的空格

Question

很奇怪……如果就这样全开的话

但是当我看到右边有一个空的 space 很奇怪。它来自哪里？

我的一次全部zipped file is here. 如果有人可以提供帮助，这是我的 html:

Answer 1

更改您的 css，如下所示 html，正文（css 中的第 159 行）：

html,body
{
    min-width: 100%;
    width: 100%;
    height: 100%;
    margin: 0px;
    padding: 0px !important;
    overflow-x: hidden; 
}
