This time I will show you how to use li to arrange horizontally, and what are the precautions for using li to arrange horizontally. The following is a practical case, let's take a look.

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<meta content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" name="viewport">
	<title>li水平排列</title>
	<style>
	html{
		font-size: 20px;
	}
	@media only screen and (min-width: 320px){
    html{font-size: 20px !important;}
	}
	@media only screen and (min-width: 350px){
	    html{font-size: 22.5px !important;}
	}
	@media only screen and (min-width: 365px){
	    html{font-size: 23px !important;}
	}
	@media only screen and (min-width: 375px){
	    html{font-size: 23.5px !important;}
	}
	@media only screen and (min-width: 390px){
	    html{font-size: 24.5px !important;}
	}
	@media only screen and (min-width: 400px){
	    html{font-size: 25px !important;}
	}
	@media only screen and (min-width: 428px){
	    html{font-size: 26.8px !important;}
	}
	@media only screen and (min-width: 432px){
	    html{font-size: 27.4px !important;}
	}
	@media only screen and (min-width: 481px){
	    html{font-size: 30px !important;}
	}
	@media only screen and (min-width: 569px){
	    html{font-size: 35px !important;}
	}
	@media only screen and (min-width: 569px){
	    html{font-size: 40px !important;}
	}
	body{
		margin: 0;
		padding: 0;
	}
	ul{
		width: 100%;
		margin: 0.3rem 0;
		padding:0.3rem 0;
		border-top:0.05rem solid #ccc;
		border-bottom: 0.05rem solid #ccc;
	}
	li{
		width: 33%;
		list-style-type: none;
		display:inline-block;
		font-size: 0.8rem;
		border-left: 0.05rem solid #ccc;
		text-align: center;
	}
	</style>
</head>
<body>
	<ul>
		<li>我是第一个li</li>
		<li>我是第二个li</li>
		<li>我是第三个li</li>
	</ul>	
</body>
</html>

##There will be a problem in this case. Set the width of li to 33%. The width of the three li tags actually exceeds one line. One obvious thing is that the li tag has a little more white space.

1. FloatingThe first thing that comes to mind is floating. Add the style float:left to li.

The effect is as above. In this way, there will be a problem with floating, that is, the floating of li makes the height of ul 0. To solve this problem, there are three Method:

1. Add height to ul, but this cannot be adaptive.

2. Be clear about the impact of floating. Add an empty p after the last li tag,

(Personally recommended, but I feel that the code maintenance is not very good. OK.)

3. Add the zoom attribute to UL, which seems to be only suitable for IE (I haven’t researched it).

##2. Write the li tag in one line

< ;ul>

I am the first li

I am the second li

I am the third li

It’s strange why this is normal, it’s hard to understand for the time being.

##3. Add styles to ul and remove the white space between li tags

Adding font-size:0 style to ul can remove the space between li tags. Something to note is that you need to reset the font size of the li tag.
