Help making responsive boxes with bootstrap

I am looking to create 3 boxes, with a button option to select what to pay.  Could someone lead me in the right direction on how to create the boxes similar to the attachment.   I need these to stack when viewed on a phone.  I do have bootstrap installed and am using it in other parts of the program.

Bootstrap actually does this very well using row and col- classes. The col dimension is separated into 12ths and Bootstrap has predefined media query breakpoints.

Here's a jsfiddle demonstrating.

NOTE: div border added for demonstration visibility.

How can I keep the sizes to be so big when on desktop and also 3 across on a phone.   So the boxes are always the same size regardless of what text is in the box.  Want something similar to picture I sent/

Picture of what I would like to do.

You want the text boxes to always be the same size regardless of viewport size? That's a departure from responsive design but it can be done using media queries and breakpoints. You wouldn't use Bootstrap for this since Bootstrap would follow all the responsive guidelines.

I'm sorry I meant I want them all to stay the same size in realation to each other, not in relation to the view point size.  Mine seem to change size, 1 may be wider than the other based on the text inside the box.
Russ SuterSenior Software DeveloperCommented:
Ah. I think I understand now. It would seem your content is either forcing the container to widen or the content is overflowing.

Can you provide an example of what you're doing so I can dissect and fix it?

Here is the code I have so far and what it looks like.  I am fine with the full screen, but when we go to phone size, I need them stacked or all across just sdesktop viewphone viewmaller.

So what's happening there is your input box is forcing the container to remain large enough to encompass it. That should be solvable by adding class="form-control" to the input element.
