Flat UI Free is a flat-design theme and component framework built on top of Bootstrap 3, distributed as compiled CSS/JS, LESS/SCSS sources, icon fonts, and HTML examples. It restyles Bootstrap components such as buttons, inputs, selects, navigation, sliders, and progress bars in a cohesive flat visual style.
Use cases
- give a bootstrap site a flat design look
- find a free flat ui bootstrap theme
- style buttons inputs and nav components with flat colors
- build a responsive website with pre-designed components
- get flat icon fonts and color swatches for web design
- download flat ui css and js for a prototype
When to choose
- you are already using Bootstrap 3 and want a polished flat theme
- you need a quick, free set of flat-styled UI components for a site or prototype
- you want matching icon fonts and a curated color palette out of the box
When to avoid
- you use Bootstrap 4/5 or another CSS framework, since the theme targets Bootstrap 3
- you need a modern, actively developed design system with current web standards
- you want a JavaScript component library rather than a CSS theme
