Hello
I don't know how I should make the design that the buttons will be equal line and not that one button will be below than other buttons.
My code is this:
I did attach the screenshot:

I use the bootstrap 3.4.1 version. Is there a solution that the page will recognize in that 6 cards, which has the most length and then put the all of the buttons similar level as the button which has most the text?
As you can see "offline settings" button is more below than the other buttons because above message is longer.
I did read d-flex method which I tried to use but didn't work for me.
Thank you in advance the answers.
