material design lite 在我的网站上不工作

Question

我尝试使用 google material design lite 制作一个 html 模板并添加 header 它工作正常但是当我在它下面添加任何东西时，它只是移动到顶部。请参阅代码以获取帮助：

.demo-layout-transparent {
  background: url('https://images.unsplash.com/photo-1456428199391-a3b1cb5e93ab?ixlib=rb-0.3.5&q=80&fm=jpg&crop=entropy&s=db130336e8134fc3f734dbc4318f5c5e') center / cover;
  font-family: 'League Spartan';
}

.demo-layout-transparent .mdl-layout__header,
.demo-layout-transparent .mdl-layout__drawer-button {
  color: white;
}

.mdl-layout-title {
    font-family: 'League Spartan';
    font-size: 3em;
    margin-top: 1em;
}

.subtitle {
    font-family: "League Spartan";
    font-size: 4em;
    color: floralwhite;
    text-align: center;
    margin-top: 2em;
}

.subtitle span{
    color: deepskyblue;
}

Answer 1

我不确定目标是什么，但请尝试将您的内容放入主要元素中。

<main class="mdl-layout__content">
  <div class="page-content"><!-- Your content goes here --></div>
</main>

或添加一个 header 元素。

Answer 2

内容应在 <div class="page-content">.
中 编辑： Header 在您的页面中是透明的。我从 Header class 中删除了 --transparent 以获得颜色。 CSS 也已通过将 margin-top 的大小更改为 5px 进行了更新（3em 对于 header 来说太大了）。 Header 标题的字体大小也从 3em 更改为 2em。也删除了 <div class="home"> 因为没有用。

  font-family: 'League Spartan';
}

.demo-layout-transparent .mdl-layout__header,
.demo-layout-transparent .mdl-layout__drawer-button {
  color: white;
}

.mdl-layout-title {
    font-family: 'League Spartan';
    font-size: 2em;
    margin-top: 5px;
}

.subtitle {

    font-size: 4em;
    color: floralwhite;
    text-align: center;
    margin-top: 2em;
}

.subtitle span{
    color: deepskyblue;
}
