That three column design that looks decent on your laptop is not exactly tablet friendly. Because your website will scale down on most tablet devices the moment a user loads your website which crams content between left and right sidebars they are already battling to find and zoom in on your content while it competes with other elements. In the case of developing a website that works for both a desktop user and a tablet user the “keep it simple stupid” method is a smart choice to make. As an added bonus when you scale down your sites output you reduce server load which in turn helps pages load faster, an important aspect for many tablet users who may not be connected to high speed internet options at all times.
Tablet devices have “dumbed down” the electronics industry by offering less robust (in some aspects) yet far more functional computing, therefore it only makes sense that the browsing experience on tablets should also be scaled down while implementing more functional design applications. While there are many web design standards you can use to create a useful and enjoyable tablet web browsing experience the options listed above should point you in the right direction to get started.
