This is a visualizer tool for CSS linear-gradients.
This was first developed on codepen: http://codepen.io/captainbrosset/details/ByqRMB/
I also wrote an article about linear-gradients: https://medium.com/@patrickbrosset/do-you-really-understand-css-linear-gradients-631d9a895caf
Note, I deleted the master branch on this repo. The default branch is gh-pages.
