Instead, we’re gonna promote these user-interface elements that will come super handy next time you work on some wireframes or prototypes. Pre-made menus, buttons, carousels for your websites and iPhone and smartphone-specific items, generously shared by Yahoo!, in their Developer Network section. Among the files, they’ve even included the most common grids for you, designers.

You can download the editable PDF files, the PNG and more formats here. Store them preciously.

Patterns are optimal solutions to common problems. As common problems are tossed around a community and are resolved, common solutions often spontaneously emerge. Eventually, the best of these rise above the din and self-identify and become refined until they reach the status of a Design Pattern.

Drag-and-drop modules, navigation tabs, object ratings, vote-to-promote, many designers already did the head-scratching, and best practices are shared from A to Z.
