In this tutorial we’ll learn how to use a <div> container to structure the top section of the webpage. We will use the style attribute to specify the height of our <div> container, apply a background image, and specify that the background image should cover the entire area of the <div> container.

Note that we have added the comment <!--First section--> to help organize our HTML code. A comment is a piece of code that is ignored by the browser. Comments are used to help explain or organize code to developers. They are created with the opening tag <!-- and the closing tag -->.
请注意，我们添加了注释<!--First section-->以帮助组织HTML代码。 注释是浏览器会忽略的⼀段代码。 注释⽤于帮助向开发⼈员解释或组织代码。 它们是⽤开始标记<!--和结束标记--> 。

保存⽂件并将其重新加载到浏览器中。 您应该会收到以下信息：
Alternately, you can use a background color instead of a background image. To use a background color, replace the <div> element code snippet you just created with the following highlighted <div> element code snippet like this:

Save the file and reload it in the browser to check your results. The background image should now be replaced with a container that is the same size but has a solid yellow color.
保存⽂件，然后将其重新加载到浏览器中以检查结果。 现在应使⽤⼤⼩相同但颜⾊为黄⾊的容器替换背景图⽚。
If you compare the <div> container on your site with the same <div> container on the , you may notice that your webpage’s <div> container is surrounded by a small margin of white space. This margin is due to the fact that all HTML pages are automatically set to have a small margin by default.
如果⽐较<div>与同⼀⽹站上的容器<div>在容器 ，你可能会注意到你的⽹页的<div>容器是由⽩⾊空间⼩幅度的包围。 此裕度是由于以下事实：默认情况下，所有HTML页⾯均⾃动设置为较⼩的裕度。
To remove this margin, we need to add a style attribute to the opening <body> tag that sets the margin of the <body> element of the HTML page to 0 pixels. Locate the opening <body> in your index.html file and modify it with the highlighted code:
要删除此空⽩，我们需要在开始的<body>标记中添加⼀个style属性，以将HTML页⾯的<body>元素的空⽩设置为0像素。 在index.html⽂件中到开头的<body> ，并使⽤突出显⽰的代码对其进⾏修改：
<body style=“margin:0;”>
<body style =“ margin：0;” >
Save and reload the file in your browser. There should now be no white margin surrounding the top <div> container.
在浏览器中保存并重新加载⽂件。 现在，顶部<div>容器周围应该没有⽩边。
You should now know how to add a <div> container with a background image to structure the top section of a webpage.
