Make It Responsive
Make sure that the site you are designing is responsive across all major devices. If a site is not responsive across major devices, it would be losing potential customers. Even Google provides high rank for the sites that are responsive in nature.
Fonts Should Be Easy To Read
Website designers should try to focus on improving user-experience. So the style and size of the font should be carefully chosen. Here, you need to make sure that the font style that you would be choosing is easy to read across all devices. If the font is too small, visitors will find it hard to read the content and it can be bad for a site.
