One of the keys to building a successful app or tool is to make sure that the user interface looks attractive. This is a basic, yet very real fact. And in this day and age, an attractive design basically equals flat design. But not just any old flat design … you need flat design that’s pixel perfect.
It’s called the Classic UI Kit. Inside, you’ll find numerous UI elements in a handful of categories, such as: buttons and other basic elements, switches, sliders and progress bars, checkboxes, radio buttons, search fields, input fields, navigation elements, drop-down boxes, visualization of steps, notifications, tooltips, pagination, and more.
But that’s not all. There are eight different color schemes, and of course, you can create your own too. The kit comes in .PSD and .SKETCH formats.
