Materialize vs UiKit

Since Materialize follows Google's guidelines for Material design, which in theory is device agnostic, Materialize itself is device agnostic too. It's designed to look good on every device.

CSS components: Badges, buttons, cards, collections, footer, forms, icons, navbar, pagination, preloader.

JavaScript components: Collapsible, Dialogs, Dropdown, Media, Modals, Parallax, Pushpin, ScrollFire, Scrollspy, SideNav, Tabs, Transitions, Waves.

Mobile-specific: slide-out drawer menu, toasts.

While the default style is not bad at all, Materialize also gives developers the ability to customize it and fit their own style, while still keeping in line with the Material Design philosophy.

Along with the CSS files, designers can also download the SASS files which can be edited and compiled.

Material design is very opinionated on how design elements should behave and look. The basics of which revolve around certain visual elements (physics, space, momentum and light) which are used to create specific UX elements.

This is very helpful because it creates a consistent feel without making every design look the same. This can be seen in Materialize too, where each element may be customized but still it keeps the consistent look of the material design.

The code is pretty clean and follows well-defined conventions.

There are plenty of ready to use themes available from the official website. You can choose the theme that you want to use from the dropdown menu and then download the CSS, LESS or SASS file for that theme to use for the website.

When using UIKit classes, it is used with the ui- prefix which is very good. Components are explained straight-forward.

UiKit has some built-in animation features which can be used to animate various components.

UiKit has a pretty good and clean style even out of the box without any customization needed.

UiKit's rather minimal style can be easily customizable to create an entirely new look to fit the needs of the designer.

Every aspect of the framework is designed to be modular, this way designers can easily choose which components to add to their stylesheet without risking to damage the overall style.
