What is the difference between border:0 and border:none:
The effect of setting the border of an object to border:0 and border:none is the same. You can cancel the border. Code The example is as follows:

<!DOCTYPE html><html><head><meta charset="utf-8"><meta name="author" content="http://www.51texiao.cn/" /><title>蚂蚁部落</title><style type="text/css">div{  width:200px;  height:200px;  border:2px solid red;  border-bottom:none;  border-left:0;}</style></head><body><div></div></body></html>

It can be seen from the operation of the above code that the border can be canceled by setting the border to 0 or none. From the appearance, the two are the same, but still There is a big difference. border:0 can set the width of the border to zero. Although it is not visible visually, the browser will still render it. border:none means there is no border directly and the browser will not render it. Therefore, the execution effect is slightly higher when set to none. Of course, this difference is basically negligible.
