WordPress - Minimal theme

Some people only want to build their website from one slider. You could use this theme for it, because it’s optimized, and won’t load anything else, just a slider (if you don’t have other plugins).
Go to your ftp, to the wp-content\themes\ folder and create a folder, which will be the name of your theme. Create an index.php file with this code in it, just replace the slider’s shortcode with yours:

<!DOCTYPE html>
<html <?php language_attributes(); ?>>
    <head>
	<meta charset="<?php bloginfo('charset'); ?>">
	<meta name="viewport" content="width=device-width">
	<title><?php bloginfo('name');?></title>
	<link rel="profile" href="http://gmpg.org/xfn/11">
	<link rel="pingback" href="<?php bloginfo('pingback_url'); ?>">
	<link rel="stylesheet" href="<?php echo get_template_directory_uri(); ?>/style.css">
	<?php wp_head(); ?>
    </head>
    <body>
	<div id="container">
	    <?php
	    echo do_shortcode('[smartslider2 slider="568"]');
	    ?>
	</div>
	<script>
	    jQuery(window).load(function() {
		jQuery(window).trigger('resize');
	    });
	</script>
	<?php wp_footer(); ?>
    </body>
</html>
Then create a style.css file, and put this code in it:
html, body{
    margin:0;
    padding:0;
}
#container{
    width:100%;
    overflow: hidden;
}

You can put more sliders with more shortcodes at the echo do_shortcode part, if you want to, also this theme is pretty small, and easy to understand, so you might be able to modify it to fit your needs.
