Question

我在这里有一些非常基本的html和css，并且对于我的图像，我用我的css设置的背景图像没有垂直重复，或者它是否被这个白色空间覆盖，但是问题是，从我的图像不再垂直重复的那一点开始就有纯白色空间，我甚至尝试设置＃content2的背景颜色和空白甚至超过骑行。任何人都可以看到我失踪了吗？ HTML：

<title></title>

Answer 1

CSS中的负边距是导致此问题的原因：

#two {
    margin-top: -104px;
    margin-left: 360px;
}

不使用较大的负边距来移动东西，而是使用浮点数：http://www.w3schools.com/cssref/pr_class_float.asp。

以下是CSS-tricks的教程：http://css-tricks.com/all-about-floats/。

在您使用负边距的任何地方，您需要使用浮点数替换。白色空间与预期一致，您设置的负边距不会影响高度。

任何人都可以找到这个白色空间来自哪里？
