😻A wireframe cannot be boring anymore
Contra was started just for fun to publish some shot on Dribbble. After designing some screens, I thought why don’t create something that will helps others to create beautiful wireframe easily. So, here it is.
The entire set of components are organised and layers and easily customisable. Also, it contains more than 50+ ready to use screen-based on common patters.
The library is under license CC0. This means it’s Free for Commercial and Personal Use: no need to credit, license, or anything.
