<p dir="auto">In this simplified example I want to explain my problem using the grid-system. When I understand the grid system right you can add as many cols as you like in one row and when the 12-grids are full the next col break into the next line.</p>
<p dir="auto">Until rc1 the following example worked well but with the release of Bootstrap 3.0 I've got an error. I think it's because of the missing "float:left" on the col-xs-12, col-sm-12 ... classes.</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="&lt;div class=&quot;row&quot;&gt;
    &lt;div class=&quot;col-xs-4&quot;&gt;Col 1&lt;/div&gt;
    &lt;div class=&quot;col-xs-4&quot;&gt;Col 2&lt;/div&gt;
    &lt;div class=&quot;col-xs-4&quot;&gt;Col 3&lt;/div&gt;
    &lt;div class=&quot;col-xs-12&quot;&gt;Col 4&lt;/div&gt;
    &lt;div class=&quot;col-xs-6&quot;&gt;Col 5&lt;/div&gt;
&lt;/div&gt;"><pre class="notranslate"><code class="notranslate">&lt;div class="row"&gt;
    &lt;div class="col-xs-4"&gt;Col 1&lt;/div&gt;
    &lt;div class="col-xs-4"&gt;Col 2&lt;/div&gt;
    &lt;div class="col-xs-4"&gt;Col 3&lt;/div&gt;
    &lt;div class="col-xs-12"&gt;Col 4&lt;/div&gt;
    &lt;div class="col-xs-6"&gt;Col 5&lt;/div&gt;
&lt;/div&gt;
</code></pre></div>
<p dir="auto">Can you tell me why the float:left has been removed with the rc2 of bootstap 3?</p>
<p dir="auto">Example:<br>
`</p><div dir="auto"><p dir="auto"></p>
  <div dir="auto">.col-xs-6 .col-md-4</div>
  <div dir="auto">.col-xs-6 .col-md-4</div>
  <div dir="auto">.col-xs-6 .col-md-4</div>
</div>`
