One more plugin I really like is the iCheck jQuery plugin for radios and checkboxes. This free plugin was released years ago and when I first saw this I knew it was a game changer.
You can dig through Google and find tons of custom checkbox/radio input styles. But iCheck is probably the best in show with the most styles, extra features, and the greatest support.
It works the same across all browsers including iOS/Android devices. Plus it supports screen readers and ARIA attributes for accessibility.
Not to mention you have a choice of 6 different themes and the choice to restyle your own theme from scratch. Pretty cool! Especially for a plugin built solely to change up two very plain input fields.
