can i make 2015 horizontal layout?

i would love one of you guys until the end of time, IF, you could tell me how to make 2015 a horizontal layout. examples: 1. just like wordpress.org but with mega menus. which http://www.nike.com/us/en_us/ shows the simple clean look i’d like to achieve too.

i have no real coding ability, i only do what i see you guys post in the forums/help. “copy this code to child theme” or copy/paste to functionality.php…

and i don’t change code that will be wiped out in the next WP/plugin update. i have no ability to keep track and update.

the best i’ve been able to do by myself is using siteorgin pagebuilder with vantage theme basic. i’ve had some trouble where it doesn’t work with some plugins, mega menus…

the best i could do is take a site like this http://tributarykayaks.com/ 2014 theme
and come up with this siteorgin plugins/vantage theme to this http://airekayak.com/ but i’m not satisfied. but really the pagebuilder is great for a person with my low tech abilities but i hope to achieve a wordpress.org or http://www.nike.com/us/en_us/ look!

thank you for any help!
