Responsive 2 column form
Author: Dynamic Drive
This is a clean, two column form that's also responsive, turning into a single column spanning the entire width of the page when the window's size is 480px or less. The two column design and large controls are meant to make the form more inviting to fill out, by breaking up the text input fields into two columns, thus appearing less overwhelming to complete. Beautiful forms equate to inviting forms!
