The width of the picture in rich text used by wechat applet exceeds the problem

Many methods are available online But it can't solve this problem
Such as to img Tag plus width:100%;height:auto; But it didn't work

The way I found is to use css Property selector for to img Plus the style of 100% width It turned out to be a success

[alt]{
    
	max-width:100%;
}

It's that simple I hope I can help you
