To sum up, to center the content in the div horizontally, you can use text-align:center;
To achieve vertical centering, the container's display:table; and the wrapper's display:table-cell; at the same time vertical- align:middle; can center the image in the div horizontally and vertically.
If there are multiple pictures, to achieve centering:
Code:
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>div水平垂直居中</title> <style> *{ margin:0; padding:0; } div.container{ background-color:pink; border:2px solid #000; width:700px; height:500px; margin:0 auto; margin-top:50px; } div.wrapper{ text-align:center; margin-top:28px; } div.wrapper img{ border:1px solid #ddd; width:200px; margin:10px; } </style></head><body> <div class="container"> <div class="wrapper"> <img src="girl3.jpg" alt="美女"/> <img src="girl3.jpg" alt="美女"/> <img src="girl3.jpg" alt="美女"/> <img src="girl3.jpg" alt="美女"/> <img src="girl3.jpg" alt="美女"/> <img src="girl3.jpg" alt="美女"/> </div> </div> </body></html>IE6/IE7/IE8/Firefox/Chrome/Safari/Opera page effect:
text-align:center; in div.wrapper achieves horizontal centering, margin-top:28px; achieves vertical centering.
28px=[500-(200 1 1 10 10)*2]/2, that is, the height of the outer layer minus the height of the inner layer, then divide by 2, set margin-top, and it will be centered.
