Div tag, we call it layer, div is a block element, and combined with css, it can be used for web page layout
Let’s first write a div+css code to let everyone see what div is. Like this
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style type="text/css">
div{
width:300px;
height:300px;
border:1px solid red
}
</style>
</head>
<body>
<div></div>
</body>
</html>The above piece of code, and then we run it to display a square with a width and height of 300 pixels and a red border
Then we will lay out the homepage of the website. It looks like this
The top piece is used as a carousel image
The bottom piece is the navigation, and then the content part. The content part is divided into left and right blocks, and then the bottom block is Let’s see how it is made. To make a web page, we need to have the basics of html and css, such as id selectors and class selectors.
When using div+css for web page layout, we need to use float. If If you don’t know this knowledge, you can refer to the CSS video tutorial or text tutorial on the PHP Chinese website. As mentioned above, the example we are going to do
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style type="text/css">
*{margin:0;padding:0;}
#div{
width:100%;
height:300px;
background:#f69;
}
#daohang{
width:100%;
height:50px;
background:#f60;
}
ul li{
list-style:none;
float:left;
line-height:50px;
margin-left:130px;
}
#bdy{
width:100%;
height:500px;
background:green;
}
#left{
width:30%;
height:500px;
background:red;
float:left;
}
#right{
width:70%;
height:500px;
background:#ccc;
float:left;
}
#but{
width:100%;
height:200px;
background:#f60;
}
</style>
</head>
<body>
<div id="div">

<div id="daohang">

</div>
<div id="bdy">
<div id="left">公司公告</div>
<div id="right">公司新闻</div>
</div>
<div id="but">底部信息</div>
</body>
</html>actually does not have much code. It is also very simple, but it is still very important for you to pay attention to the difference between margin and padding. Margin is the distance between the border and the padding. The distance between the content and the border. Many friends say that the attributes in CSS cannot be remembered. For I think you can’t remember this part because you haven’t practiced enough. You can only remember it if you write more and practice more!
