代码如下:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>居中</title> <style type="text/css"> *{ padding: 0px; margin: 0px; } body { height: 100%; overflow: hidden; } .father{ position: absolute; height: 500px; width: 100%; background-color:#2AABD2; } .children{ position: absolute; top: 50%; left: 50%; background-color: red; width: 100px; height: 100px; margin: -50px 0 0 -50px; } </style> </head> <body> <div class="father"> <div class="children"> </div> </div> </body> </html>
效果图如下:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>居中</title> <style type="text/css"> *{ padding: 0px; margin: 0px; } body { height: 100%; overflow: hidden; } .father{ height: 500px; width: 100%; background-color:#2AABD2; display: flex; justify-content: center;/*实现水平居中*/ align-items:center; /*实现垂直居中*/ } .children{ background-color: red; width: 100px; height: 100px; } </style> </head> <body> <div class="father"> <div class="children"> </div> </div> </body> </html>
效果图如下:

多谢@alexxxcs1提供的另一种方式(不晓得这样能否@到^_^),嘛其实网上实现居中的方式确实很多,互相探讨加深印象。
/*垂直居中,div上边界距离窗口上边的距离为窗口高度的50%,并针对不同浏览器进行兼容。-- 在外层添加一个div,把行内容居中,添加.row .justify-content-center -->
