CSS to change image URL
<p>How can I use an entirely separate CSS file to change/override only the URL for the image IMAGE.png?</p>

<pre><code>&lt;div id="id1" class="class1"&gt;
    &lt;div id="id2" class="class2"&gt;
        &lt;div class="class3"&gt;
            &lt;div id="id3"&gt;
                &lt;a class="logo" href="http://domain.com" tabindex="-1"&gt;
                    &lt;img src="https://IMAGE.png"&gt;&lt;/img&gt;
                &lt;/a&gt;
            &lt;/div&gt;
        &lt;/div&gt;
    &lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>Thanks so much!</p>
