Copy form elements from DigitalOcean

I would like to the form elements DigitalOcean uses in their add credit card form. Your job is to give me an example HTML file which is built on Bootstrap that showcases each form field so I can re-use them in my web site. It should include all transitions and necessary JS code as well. I should be able to change the blue color as well. I already have a [login to view URL] file. You should include it in the sample HTML page so your code should work seamlessly with this file included. I need the input box, password field, select box, checkbox, radio button. All should be in the DigitalOcean's format. To find the form I'm talking about: 1- Head over to [login to view URL] and sign up or sign in if you are already a member. 2- Go to settings and then billing. 3- Click on Add Credit Card and the form will display.
