如何仅使用css在html页面上显示图像？

#got-easier { background-image: url(/i/trend-down.gif); }

display: block;

<img>

/* Leahy Langridge Method */
span#imageName {
  display: block;
  height: 0 !important;
  overflow: hidden; 
  padding-top: 0px;  /* height of image  */
  width: 0px;  /* width of image */
  background: url(url/of/image.jpg) no-repeat
}

/* Phark Method */
span#imageName {
  display: block;
  width: 0px; 
  height: 0px; 
  background: url(url/of/image.jpg) no-repeat; 
  text-indent: -9999px
}

#got-easier {
  display:inline;
  position:absolute;
  width:img-Xpx;
  height:img-Ypx;
  background:url(/i/trend-down.gif) no-repeat;
}
