Directly add the style img{vertical-align:bottom; display:block}
Of course it doesn’t work in some cases. For example, I want to add three pictures, top, middle and bottom, and the middle picture is set as the background. I found this method Invalid, just the gap between the top and middle pictures is gone, but there is still a gap between the bottom and the middle. The method is very simple. Change vertical-align:bottom to top. You can set the parameters of vertical-align according to the different situations you encounter.
Method 1:
img{vertical-align:top; display:block}
<style> #l1 {float:left;background:#000;} #l1 ul li {list-style:none;padding:0;margin:0} img {vertical-align:bottom; display:block;} </style>
Method 2: Set container font-size:0 (Personally think this method is the best!!!)
