CSS:
CSS:
/* where margin-left = {img width}/2, and margin-top= {img height}/2 */
.bigdiv {
width:100%;
height:100%;
position:absolute;
}
.bigdiv img {
position:absolute;
left:50%;
top:50%;
margin-left:-10px;
margin-top:-10px;
}
HTML:
HTML:
<div class="bigdiv"><img src="eg.png" /></div>
You could also put your margin-left, margin-top commands as a style on the img tag instead (since they're unique per image).
您也可以将 margin-left、margin-top 命令作为 img 标签上的样式(因为它们在每个图像上都是唯一的)。
