If cancel the twitter bootstrap navbar collapse
<p>I work on a php website and use bootstrap library. I'll cancel collapse function from the navbar. I solved the responsive problem as follows;</p>

<blockquote>
  <p><strong>hidden-(?)</strong> and <strong>visible-(?)</strong></p>
</blockquote>

<p><strong>Simple:</strong></p>

<pre><code>&lt;li&gt;
  &lt;a href="#"&gt;
    &lt;span class="glyphicon glyphicon-map-marker visible-sm-block visible-xs-block"&gt;&lt;/span&gt;
    &lt;span class="hidden-xs hidden-sm"&gt;Contact&lt;/span&gt;
  &lt;/a&gt;
&lt;/li&gt;
</code></pre>

<h2>Screens</h2>

<p><strong>Medium, large and more screens:</strong></p>

<p><strong>x-Small Devices (Phone) Screen 3:</strong>
" My support minimum width for devices: 230px "</p>

<p>Does this method lead to a possible mistake? And do you think that 230px is enough? Thanks.</p>
