jQuery UI由GUI小工具、视觉效果和使用jQuery、CSS和HTML实现的主题组成。jQuery UI非常适合为网页建立UI界面。jQuery UI的Resizable containment选项用于在给定的边界元素内调整元素的大小。

语法:

$(".selector").resizable({
    containment: "parent"
});

CDN链接：首先，添加你的项目需要的jQuery UI脚本。

<link rel=”stylesheet” href=”//code.jquery.com/ui/1.12.1/themes/smoothness/jquery-ui.css”>
<script src=”//code.jquery.com/jquery-1.12.4.js”></script>
<script src=”//code.jquery.com/ui/1.12.1/jquery-ui.js”></script>

示例:

<!doctype html>
<html lang="en">
  
<head>
    <meta charset="utf-8">
    <link rel="stylesheet" 
          href=
"//code.jquery.com/ui/1.12.1/themes/smoothness/jquery-ui.css">
