Fullpage slider into the background

To be able to follow the steps of this tutorial,  you are required you to have coding knowledge! Regretfully we  can't provide support for custom coding. If you can't achieve what you are looking for or if you're not sure how to follow the instructions,  hire a developer.

If your template/theme doesn’t have anything else in there, then you could put your full page slider into the background to be in a fixed position behind everything with this code, just put it right after the <body> part of your website:

Joomla

probably into the index.php file of the template

<div style="position:fixed;top:0;bottom:0;left:0;right:0;z-index:-1;">
<jdoc:include type="modules" name="bgsliderposition" />
</div>
WordPress

probably into the header.php file of the theme

<div style="position:fixed;top:0;bottom:0;left:0;right:0;z-index:-1;">
<?php echo do_shortcode('[smartslider3 slider=16]'); ?>
</div>
If your theme has background color on its sections, you won't be able to see the slider! You'll need to do more serious modifications in the theme to make it work.
