In this day and age you will likely have at least half, if not more, of your traffic viewing your website on Tablets or Mobile Phones. I recommend making reactivity a top priority when choosing your design. If you have a good amount of content break it up into sub-pages, or link to the sections with your menu, rather than having a single page that will translate to an infinite scroll for Mobile and Tablet users. Back to the top buttons are also good stuff 🙂
