Answer 1

well, I found solution for this problem. I use bootstrap 3 sub theme, and there is file who provide page template, it calls node.tpl.php. I just remove string <div class="main-container <?php print $container_class; ?>"> and now it works well.

Answer 2

go to page.tpl.php file, remove the lines that render the header, the logo and the title. They would usually be in an if statement and the varibles are $logo, $site_name, $main_menu, $title.
