Gridlayout

make a 2/3 and a 1/3 grid ( via set cell size)
pull in the 2/3 grid a 1/1 container and in the 1/3 grid 2 1/1 containers:
click on it to enlarge the image:

if you have to have that grid not fullsize – give the grid-row a custom class: on my test page it is: grid-notfull
put this into functions.php of your child-theme:

function grid_layout_notfull(){
?>
<script>
(function($){
    $('.av-layout-grid-container.grid-notfull' ).wrap( '<div class="main_color notfullsize"></div>');
    $('.notfullsize').css({"clear": "both", "width": "100%" , "float": "left" , "position": "static" , "min-height": "100px" });
    $('.grid-notfull').css({"max-width": "1310px", "margin": "0 auto" , "padding": "0 50px"});
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'grid_layout_notfull');

you have to adjust it then to your needs ( above are the default settings with 1310px width and 50px left/right padding )
