Oh, that&#x27;s awesome.<p>The CSS is clearly setting these to display:block, so they should in fact stack.  But the page is also in quirks mode (no doctype), and in quirks mode Chrome (and WebKit) seems to compute the display of &lt;td&gt; to &quot;table-cell&quot; no matter what the styles say.<p>So yeah, someone just wrote CSS that depends on a bug in Chrome&#x2F;WebKit and either didn&#x27;t bother to test in other browsers or doesn&#x27;t care whether it works there.<p>Edit: <a href="https:&#x2F;&#x2F;code.google.com&#x2F;p&#x2F;chromium&#x2F;issues&#x2F;detail?id=369979" rel="nofollow">https:&#x2F;&#x2F;code.google.com&#x2F;p&#x2F;chromium&#x2F;issues&#x2F;detail?id=369979</a> is the 1.5-year-old bug report on Chrome to remove this unnecessary quirk.  Let&#x27;s see what HN does if&#x2F;when the Chrome folks fix that one...
