More and more people are switching to mobile phones as their primary browsing method. That means it’s becoming urgent and essential that your website is designed with that in mind. It needs to be compatible and sized to fit cell phones and computers.
Your website should automatically know the difference between which device the user logs in with and display your site accordingly based on that information.
Mobile-friendly websites are called “Responsive”. and should be scalable between all devices including computers with large screens, tiny cells phones, and ipdas in the middle.
