Are there any specific guidelines for structuring CSS and PHP includes to avoid layout issues like the one described in the thread?

The issue described in the thread could be due to the CSS and PHP includes not being structured properly, leading to layout issues. To avoid such problems, it's important to include CSS files in the <head> section of your HTML document and PHP files at the top of your PHP files before any HTML output. This ensures that styles are loaded before content is rendered, preventing layout issues.

&lt;?php
include &#039;header.php&#039;;
?&gt;

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;link rel=&quot;stylesheet&quot; type=&quot;text/css&quot; href=&quot;styles.css&quot;&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;!-- Your content here --&gt;
&lt;/body&gt;
&lt;/html&gt;

&lt;?php
include &#039;footer.php&#039;;
?&gt;
