为什么我的网站左侧有很大的空间？

Question

浏览器中出现网站 html 左侧的一个非常宽的空间。我不知道原因，也不知道是什么时候发生的。 我在这里上传了我的网站：http://kfs-saintgeorge.esy.es/

这是我的 CSS 文件：

Answer 1

据我所知，这是因为 direction: rtl 标记在您的 HTML 元素中。

试着把它放在#body2里面：

#body2 {
    width: 100%;
    display: flex;
    justify-content: space-around;
    align-items: flex-start;
    flex-direction: row;
    direction: rtl;
}
