Preline UI - Open Source Tailwind CSS component library

What is TailwindCSS?

A utility-first CSS framework packed with classes like flexpt-4text-center and rotate-90 that can be composed to build any design, directly in your markup.

What is Preline UI?

Preline UI is an open-source set of prebuilt UI components based on the utility-first Tailwind CSS framework.

Why use Preline UI?

Based on the Tailwind CSS utility classes, Preline UI's prebuilt components and UI elements help you quickly design and customize responsive mobile-first websites with diverse predefined components (such as modals, buttons, alerts, cards and more).

Components are grouped by visual usability criteria (components, navigation, forms, etc.) and styled directly on top of Tailwind CSS, making them easy to extend and customize. This is a lifesaver for developers looking to create a unique and eye-catching design system without the hassle of creating each component by hand.

It is a great option for new and existing projects.

... and it’s completely free! 🤯


Let's see the most exciting features with a few examples.

Plugins - We've developed a handful of completely unstyled, fully accessible UI plugins for popular features that for one reason or another don't belong in core. Available plugins (more plugins coming soon):

  • Accordion
  • Collapse
  • Dropdown
  • Mega Menu
  • Modal
  • Offcanvas
  • Remove Element
  • Tabs
  • Popover
  • Tooltip

250+ Components - We have put a lot of thought into designing all of the components to look coherent and work well together in various grid layouts. It’s an extraordinarily rich and complete UI collection for a modern web application. Nevertheless, if some components should look different according to your perspective, you can edit and customize them easily. Learn more

Dark Mode - With modern operating systems all having light and dark mode, to make this as easy as possible, all Preline UI components include a dark variant that lets you style your site differently when dark mode is enabled. Learn more

Dark Mode example

Code snippets - Each component comes with copy to clipboard feature. Just click on the “Copy” button and copy the code to your file. The hard work is done for you and makes the process easier.

We've done our best to make the documentation as thoughtful and thoroughly organized as possible with easy to navigate through different sections to help you not to struggle that much as you build different sites.
