内容图文

给定一个简单的连续文本段的基本四列布局,以及只有一个图像跨越三列,右上对齐,我们如何在最后三列上跨越我们的图像,以便我们的文本自动围绕图像流动？

.quatroColumns{}             /* css multi column 4 columns */
.imageSpanning2Columns{}     /* align to top-right */
.imageSpanning3Columns{}     /* align to top-right */
.imageDescription{}          /* description box over image */

http://jsfiddle.net/Vbr9d/205/(找到图像应该去的地方的痛苦：不简单和不优雅的开始！)
http://jsfiddle.net/Vbr9d/206/(看起来很丑陋,但HTML开始优雅地分离图像和文本pragraph！)

*忘记旧的浏览器版本,除了当前主流版本：Firefox,Internet Explorer,Chrome,Safari.欢迎任何想法,方向或实验.用于将段落文本自动拆分为不同div的替代JavaScript实现也是受欢迎的.

解决方法:

这是一个清理的解决方案,应该适用于所有主流浏览器.它继承了绝对定位的图像而不是使用列跨度,因为Firefox尚不支持它.

  position: relative;

  padding-top: 225px;
}

article img {
  /* Absolute position our image */
  position: absolute;

  /* Place it in the top right cornet */
  top: 0;
  right: 0;

  /* Give it a height of 200px, this can of course be change if needed. If you update the height here make sure you also change the padding-top of the article and the negative margin later down. */
  height: 200px;
  
  /* We only want the image to spread 3 columns in width, that's 75% of the entire width. We also use 10px (half of the column-gap). */
  width: calc(75% - 10px);

}

/* Give the first paragraph a negative margin to pull it back up. (right now we're only using one parapgrah but if you'd want more in the future lets be specific here) */
article p:first-of-type {
  margin-top: -225px;
}

/* Some media queries to make it look nice on all resolutions */

对于这个codepen的scss版本看看

这个答案最初包含使用column-span的解决方案(遗憾的是Firefox尚未支持).作为参考,我已将此解决方案添加为此问题的单独答案.
