<p dir="auto">Dear all,</p>
<p dir="auto">Now that bootstrap v. 3.0 is out how to use it on an existing site made with bootstrap v. 2.0? Any help/suggestions is appreciated!</p>

<p dir="auto">Take this piece of code, for example. The width of the right and left border on the input-group-addon are two pixels, while they should be one.</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content=" &lt;div class=&quot;input-group&quot;&gt;
  &lt;input type=&quot;text&quot; class=&quot;form-control&quot; &gt;
  &lt;span class=&quot;input-group-addon&quot;&gt;Hello&lt;/span&gt;
  &lt;input type=&quot;text&quot; class=&quot;form-control&quot; &gt;
&lt;/div&gt;"><pre class="notranslate"><code class="notranslate"> &lt;div class="input-group"&gt;
  &lt;input type="text" class="form-control" &gt;
  &lt;span class="input-group-addon"&gt;Hello&lt;/span&gt;
  &lt;input type="text" class="form-control" &gt;
&lt;/div&gt;
</code></pre></div>
