我正在尝试用html编写Box和Whiskers图.问题是,我有一个div的边框(如Box中),但是当覆盖包含带状彩色图像的前一层时,这些边框会消失.如果我可以避免使用背景图像(或颜色),则首选.
html是:
<table cellspacing="0" cellpadding="0" id="BoxAndWhiskers" width="100%">
<tr class="graphArea">
<td><div class="graphColors"><img src="ReadingColorScale.png" width="100%" height="250" alt="" /></div>
<div class="graphBoxes"><img src="black.gif" width="2" height="50" alt="" class="Whisker" /><div class="graphBox"><img src="black.gif" width="100%" height="2" alt="" style="padding-top: 10px; padding-bottom: 10px;" /></div><img src="black.gif" width="2" height="50" alt="" class="Whisker" /></div></td>
</tr>
</table>
