col-md-12在col-md-6内部无法正常工作？

Question

Below is my code structure. I am trying to give full width to email column by using col-md-12 class but it's not working. I tried adding width:100% manually but still its not working.

The below is snapshot of how my view looks:

Let me know if any further details is required! Any help will be highly appreciated. Again Thank you so much.

Answer 1

To make it full width, you should use the .btn-block as mentioned in the documentation . It likely needs to be a block level element in order to be full width.

Answer 2

Bootstrap provides some examples. Yours is very similar to "Checkout Form": http://getbootstrap.com/docs/4.1/examples/checkout/

I recommend you take a look at it as it was designed and implemented by the bootstrap team. You'll find out good practices (when and how to use row, key classes to ensure responsiveness, etc).
