When designing a website or web app, it’s essential to consider the screen of the person who is going to be using it – and nowadays that means it’s more likely to be a mobile screen. In 2014, 1.8 billion phones, 256 million tablets and 276 million PCs were shipped, meaning more phones were shipped in three months than there were PCs shipped all year. But mobile devices and PC’s don’t exist in their own worlds; users are increasingly switching between devices throughout the course of completing a task. A Google study on The New Multi-Screen World found that “90% [of users] use multiple screens sequentially to accomplish a task over time.”
The new reality is that your website or web app needs to be designed to look good on any device, no matter the screen size.
