I have a making a menu on a webpage and can’t seem to get the elements to line up correctly. I have two buttons and two drop down menus, image attached below.

What sort of CSS styling can I do that will make the drop-down menus align horizontally with the ‘Go’ buttons? I tried adjusting the bottom and top margins of both elements but that doesn’t seem to be what I am looking for.
Here is the current CSS for both elements:
select.small { //<- drop downs
width: 120px;
margin-bottom: 0px;
}
button.small{ //<- buttons
margin-bottom: 0px;
}
Any input would be appreciated as I am fairly new at this.
Set the
positionof the buttons torelativeand add:or whatever is needed.
