 <p>It looks like so long as there is <em>at least one character</em> between the <code>div</code>s in the raw markup, the spacing is correct. This workaround worked for me:</p> <pre><code>div.grid div.column Item 1 . div.column Item 2 . div.column Item 3 . div.column Item 4 . div.column Item 5 </code></pre> <p>Since the <code>font-size</code> of <code>.grid</code> is <code>0</code>, the periods are not visible.</p>
