This is the first time we introduce grid view for the navigation menu bar in a style instead of traditional list view format, which means the other tabs like Home, Forum,... are hidden behind the main tab. You must click on the main Tab to open the other main tabs. This kind of view will bring to you the sense of overlapping at first, but look a deep side, you might feel the neat when the page is presented like that. Sodium style for XenForo 2, with the traditional flat design, means that it's totally fresh with a mixture of bright green and dark powder blue.
