Question

为什么我的标题和导航在不同页面上的行为方式不同？我试图制作另一个与主页面具有相同导航和标题的页面，但出于某种原因，即使它使用相同的CSS，它在我试图制作的第二页上的行为也不同。

第一页

Answer 1

测试了一下，这似乎是由于没有清除float，从#header删除负上边距然后添加最后一行CSS应该解决它：

#overlay {
width: 100%;
height: 30em;
position: relative;
clear: left;
}

您可能希望对#work执行相同操作，即使它似乎不会影响布局。

如果我可以添加 - 不是所有的花车都是必要的。例如，删除#header上的那个似乎没有任何影响。我猜它使用的越少越好。如果您愿意，可以使用这段代码摆脱水平滚动条：

#header {
color: #D7DADB;
font-family: 'Roboto', sans-serif;
font-weight: 300;
font-size : 15px;
text-align: left;
width: 100%;
padding-left: 3em;
position: relative;
height: 15%;
box-sizing: border-box;
}

为什么我的标题和导航在具有相同CSS的不同页面上的行为不同
