How do I write this shortcode? [closed]

Question

function webhosting_products_shortcode( $atts, $content = null) {
    ob_start();
    include('shortcodecontent.php');
    $shortcode = ob_get_clean();
    return $shortcode;
}
add_shortcode('webhosting', 'webhosting_products_shortcode');

Improvements include:

Your html is now in a separate file, and can be written as is, rather than as a long PHP string
Trailing whitespace is bad, untidy, and should be highlighted by your code editor to point out the waste
