Any modern website needs to be created using mobile friendly web design to be "responsive" and work well on mobile devices, tablets and desktops. As such, minimal, clean and responsive web design is the popular trend, highlighted in the examples below.
Mobile friendly web design automatically resizes, hides, shrinks or enlarges elements of a website to look good on all devices. If you view any of the examples above on a desktop screen, you can resize the browser to see how the website changes depending on the width of the window. There are plenty of online mobile friendly web design testers, but if you want to check your own website, try Google's Mobile Friendly Test.
