比如上面这种情况,footer部分本来应该位于最底部,但是main内容太少导致连在一起,影响美观
解决方案:
给footer加上margin-top:负值 值的大小为footer的高度
写了个小demo代码如下:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0;"/> </head> <body style="padding:0;margin:0;"> <div style="202px;height:202px;border:1px solid #ccc;background: #fff;overflow-y:scroll "> <div style="100%;min-height:100%;"> <div style=" padding-bottom:40px;"> Lorem ipsum dolor sit amet, consectetur adipisicing elit. Accusantium, assumenda culpa in maiores nesciunt placeat sequi. Libero neque quaerat quam unde veritatis voluptates. Commodi fugit impedit perspiciatis quam sed sit. </div> </div> <div style="100%; height:40px; background: red; color:#fff; margin-top:-40px">footer部分</div> </div> </body> </html>
注意div的嵌套关系,以及main部分的padding-bottom值(为footer留出空档大小)
