Achieving Vertical Alignment (Thanks, Subgrid!)

Our tools for vertical alignment have gotten a lot better as of late. My early days as a website designer involved laying out 960px wide homepage designs and aligning things horizontally across a page using a 12-column grid. Media queries came along which required a serious mental shift. It solved some big problems, of course, but introduced new ones, like dealing with alignment when elements wrap or are otherwise moved around in the layout.
