我正在为学校编写一个基本站点,所有对象都漂浮在各处。这很令人沮丧,我很累。不,今晚不到期。但是,我想在路上给我一些指示。我应该删除我的 CSS 代码并重新开始确保我仔细检查所有内容,还是我的边距都错了?

你想要做的是给你的页脚(你把上次修改日期的javascript放在哪里)样式“clear:both;”。这种样式防止元素与浮动元素内联混合,将其移动到它们正下方的位置。这应该可以解决大多数布局问题。

我还注意到您的代码中的一些内容,值得一提:

  • 在html中,属性中不能有空格,即:class="foo",不是class = "foo"
  • 在 css 中,float: justify并且float:center不是有效的属性。它是右还是左。
