【CSS】让图片在高宽固定的div里水平垂直都居中的三种办法
效果:
实现一:绝对定位,精算师最爱。
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>圆角Img示例</title> <style type="text/css"> .parentDiv{ width:200px; height:400px; background-color:yellow; position:relative; } .childImg{ position:absolute; height:128px; width:128px; left:36px;/* (200-128)/2 */ top:136px;/* (400-128)/2 */ } </style> </head> <body> <div class="parentDiv"> <img class="childImg" src="bggj-08.png" /> </div> </body> </html>
实现二:无须计算 自动偏移 比上面方法省事
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>图片垂直水平居中</title> <style type="text/css"> .parentDiv{ width:200px; height:400px; background-color:yellow; position:relative; } .childImg{ height:128px; width:128px; position:absolute; left:50%; top:50%; transform:translate(-50%,-50%); } </style> </head> <body> <div class="parentDiv"> <img class="childImg" src="bggj-08.png" /> </div> </body> </html>
方法三:柔性布局,但仅在Chrome中好用,Editplus3不支持,别的浏览器自己试。
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>图片垂直水平居中</title> <style type="text/css"> .parentDiv{ width:200px; height:400px; background-color:yellow; display:flex; justify-content:center; align-items:center; } .childImg{ height:128px; width:128px; } </style> </head> <body> <div class="parentDiv"> <img class="childImg" src="bggj-08.png" /> </div> </body> </html>
