overflow 属性_html/css_WEB-ITnose
写在前面的话：
2016年5月4日青年节，作为一名正青春的学生党，开始了博客生涯，励志做个勤奋上进的好青年。幻想着毕业后月薪W+ 、走上人生巅峰的职场生活......
然而 然而 然而 ，自制力有限的我昨天还是没有控制住，追起了《欢乐颂》，啊啊啊啊啊，一看就是一整天啊，简直是大写的颓废！！！
哈哈，我相信很多人也在追这部剧，在这部剧里，每个人应该都能够找到自己喜欢的角色，也应该能够从她们身上找到点点相似的地方，个人感觉是一部很值得看的剧。
不过话又说回来，剧里的故事都是别人的，还应该及时回到现实生活中，做好自己的主角，想清楚自己想要什么样的生活，或者是不要什么样的生活，踏踏实实往前走。。。
啊啊啊，请不要打翻这碗鸡汤，勿喷 勿喷 勿喷，跪谢！
还有，今天是母亲节，记得给自己母亲打个电话。。。来自
overflow 有以下四个属性（来自W3School）
1、overflow:visible
代码如下：
<!DOCTYPE html><html><head><meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><title>Examples</title><meta name="description" content=""><meta name="keywords" content=""><link href="" rel="stylesheet"> <style type="text/css"> .box{margin: auto; width: 150px; height: 50px; border: 1px solid red; overflow: visible; } </style></head> <body> <div class="box"> <img src="/static/imghw/default1.png" data-src="img/flower.png" class="lazy"/ alt="overflow 属性_html/css_WEB-ITnose" > </div> </body></html>效果如下：
overflow:visible 也是overflow 默认的属性值，如上图效果所示，超出父元素的部分会依旧显示出来，同时超出部分不会撑开父元素的高。
2、overflow:hidden
代码如下：
<!DOCTYPE html><html><head><meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><title>Examples</title><meta name="description" content=""><meta name="keywords" content=""><link href="" rel="stylesheet"> <style type="text/css"> .box{margin: auto; width: 150px; height: 50px; border: 1px solid red; overflow: hidden; } </style></head> <body> <div class="box"> <img src="/static/imghw/default1.png" data-src="img/flower.png" class="lazy"/ alt="overflow 属性_html/css_WEB-ITnose" > </div> </body></html>效果如下：
如图所示，子元素会显示在父元素内，超出父元素的部分会被隐藏。同时，在上一次清除浮动问题中也讲到过，可以给父元素加overflow:hidden，来达到清除浮动的效果。
3、overflow:scroll
代码如下：
<!DOCTYPE html><html><head><meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><title>Examples</title><meta name="description" content=""><meta name="keywords" content=""><link href="" rel="stylesheet"> <style type="text/css"> .box{margin: auto; width: 150px; height: 50px; border: 1px solid red; overflow: scroll; } </style></head> <body> <div class="box"> <img src="/static/imghw/default1.png" data-src="img/flower.png" class="lazy"/ alt="overflow 属性_html/css_WEB-ITnose" > </div> </body></html>效果如下：
如上图所示，此时设置的是overflow:scroll ,x和y方向都会产生滚动条，及时父元素的宽足够子元素的宽，也会产生滚动条，如果设置overflow-y: scroll;水平方向就不会产生滚动条，效果如下：
4、overflow: auto
代码如下：
<!DOCTYPE html><html><head><meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><title>Examples</title><meta name="description" content=""><meta name="keywords" content=""><link href="" rel="stylesheet"> <style type="text/css"> .box{margin: auto; width: 150px; height: 50px; border: 1px solid red; overflow: auto; } </style></head> <body> <div class="box"> <img src="/static/imghw/default1.png" data-src="img/flower.png" class="lazy"/ alt="overflow 属性_html/css_WEB-ITnose" > </div> </body></html>效果如下：
此时浏览器会根据父元素和子元素的宽和高，自动设置滚动条。
当然，以上overflow 的属性都是在父元素固定宽和高的基础上实现的效果。
希望以上的介绍对您能有所帮助，同时这也是我自己只是内化的过程，感谢博客园平台！----来自
