Boostrap PHP Form

Hell- I'm looking to add a simple 2 field form. I'd like it to connect to a database so that I can call on the information later, or add it to a separate page to scroll through later. I have an existing site this will be going onto, so I'd like it to match styles as well. Would also need the container resized to fit the form, and the form hidden on the mobile, unless you can make everything fit on the mobile as well. Should be a simple enough project, I just have 20 different projects on my plate right now, and don't have time for this one. Thanks.
