made changes to buttons

The reason we rearranged the buttons was do to the look on small screens, there we want the default button to be above the two other buttons. The default button is always “New question” or “Submit >>>”. Before the “New question” button became the last child so we where not able to make him appear above the others, so we arranged the buttons in javascript as they appear on small screens. On big screens the buttons are arranged : back to main menu and practice on the left and new question on the right. This can become a bit confusing do you have an idea how we can work around this? We were not sure what was the best way to do this.
