change opacity on hover bootstrap
<pre><code>&lt;button type="submit" value="Log in" class="btn btn-lg btn-link" style="color: grey;"&gt;&lt;i class="glyphicon glyphicon-log-in" style="font-size: xx-large"&gt;&lt;/i&gt;&lt;/button&gt;
</code></pre>

<p>I added inline style to change the button style property. Now it won't change opacity when I hover my mouse pointer over it. Is there a way to specify that ? I am using twitter bootstrap 3.0</p>
