css字母不到一行就换行的方法
打开一个html代码页面，创建两个div标签并输入一段英文语句。分别设置按字母自动换行和按单词自动换行两种css样式。
word-break:break-word;//表示以单词为单位换行， word-break:break-all;//表示以字母为单位换行。
代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<style>
.aa{
width:150px;
word-break:break-word;
}
.bb{
width:150px;
word-break:break-all;
}
</style>
</head>
<body>
<div class="aa">When summer comes, unlike most people, I will be very excited, because I like summer very much. People don’t like summer because of its hot weather, which makes people sweat all the time. But summer is my favorite season, I can wear fewer clothes. I like to wear short jeans and a T-shirt, I feel so free.</div>
