Why is CSS style not working?
<p>I am trying to apply a style for the HTML <code>&lt;head&gt;</code> tag. But it is not working.</p>

<p>Here is the code:</p>

<pre><code>&lt;?php

?&gt;

&lt;!DOCTYPE html&gt;
&lt;html&gt;
    &lt;head&gt;
        &lt;link rel = "stylesheet" href = "css/style.css"&gt;
        home page
    &lt;/head&gt;
&lt;/html&gt;
</code></pre>

<p>And here is the css/style.css part:</p>

<pre><code>#head {
    font-size: 15 px;
    font-family: helvetica;
    font-color: blue;
    text-align: center;
};
</code></pre>
