Align form items with CSS

Hello, I would like some help to align the items in the following form. I would like the labels of the selects to be above the same as the labels of the inputs. Additionally I would like the selects, the imputs and the buttons to be aligned in the bottom of the div. Thanks to anyone who can help me because although I tried to search I could not do it.
