Question

我网站中间有一个灰色的框。我已经仔细检查了所有的代码，我无法弄清楚是什么创造了这个。我很抱歉问这么愚蠢的问题，我对此很陌生。这是代码 -

Answer 1

删除以下属性：background-color: #eee; */，否则，我已将相同的代码放在小提琴上，并且没有发现任何问题。

用此

替换.jumbotron类

.jumbotron {
        padding: 30px;
        margin-bottom: 30px;
        color: inherit;
        }

每当遇到这样的问题时，右键单击鼠标并选择 Inspect element ，然后单击html元素（已在其上应用css）并查看已检查的属性以及哪些属性不。那么您应该轻松解决问题。

Answer 2

这是一个广泛的问题，因为你不能说出你想要出现在那里而不是这个大的灰色方块，而是要回答你的具体问题：从HTML中删除jumbotron标记，它将消失：
