HTML/CSS style tags not working
<p>For some reason, none of my style tags are being picked up either in the embedded CSS or HTML. Neither the font-family changes are not being taken into effect nor the <code>border-top: 5px solid black;</code> line. Any tips?</p>

<pre><code>&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;
        My Resume
    &lt;/title&gt;
&lt;style type=“text/css”&gt;

#ob {
    border-top: 5px solid black;
}

&lt;/style&gt;
&lt;/head&gt;

&lt;body&gt;
    &lt;div&gt;
        &lt;h1 style=“font-family: sans-serif”&gt;
            &lt;strong&gt;Corey Schnedl &lt;/strong&gt;
        &lt;/h1&gt;

        &lt;h4 style=“font-family: Sans-Serif”&gt;
            &lt;strong&gt; XXXXXXXXXXX / XXXXXXXX / XXXXX / XXXXX &lt;/strong&gt;
            &lt;br&gt;
            &lt;strong&gt;XXXXXXXXXXXXX&lt;/strong&gt;
        &lt;/h4&gt;
    &lt;/div&gt;

    &lt;div&gt;
        &lt;h3 style=“font-family:Arial”&gt;
            &lt;strong&gt;Objective&lt;/strong&gt;
        &lt;/h3&gt;
        &lt;p&gt;
            To obtain an entry-level position as a Java software developer.
    &lt;/div&gt;

&lt;/body&gt; 


&lt;/html&gt;
