作为一个新手,我正在youtube上学习一个简单的网站教程,但是我从一些简单的html碰到了砖墙。我使用Atom
作为开发区域,但这不是问题所在,因为当我进入文件系统并运行index.html文件时,它只会给我一个白屏。如您在我的代码下面看到的,我所要做的就是添加一个蓝色背景。有人可以在下面指出我的代码有任何问题吗?

fluid-container
内部必须有可见的高度/宽度。它可能只是一个简单的<p>Hello</p>
尝试以此替换您的代码:
<div class="fluid-container">
<div class="blue-back">
<p>Hello world</p>
</div>
</div>
现在蓝色背景就在那里

问题:
您已经创建了<div>
,但其中没有内容,因此默认的高度和宽度为0px
而且类名“ blue-back”不在引导程序中,请确保已在另一个css文件中创建了它。
请在下面查看由引导程序给出的示例背景class
