how can I make it print full html page?

[yoske25]

Hi. Great plugin! :)
I want to basically have a "help" page for my clients so they know how to reach me.
I want to design in a little bit so I used HTML + CSS files and created a designed page with information, link, and stuff like that.

I can't seem to get the code to show all the page (includes his css)

this is what I've changed

function wpse_91693_render()
{
    global $title;

    print '<div class="wrap">';
    print "<h1>$title</h1>";
    print '</div>';

    $file = plugin_dir_path( __FILE__ ) . "index.html";

    if ( file_exists( $file ) )
        require $file;

    print "$file"; // this line

}

You have to change the method for enqueuing the CSS file. Use your own file name there, that should work. Make sure the path matches. Good luck!
