Liquid layouts are decidedly out-of-fashion. Fixed-width, centered layouts have become the dominant design pattern for the Web, and for good reason too. Fixed-width layouts allow designers to define strict proportions between columns, and keep line-lengths under control.
But, setting a fixed width isn’t the only way to maintain a reasonable measure. There’s a very reasonable alternative that is rarely explored — variable type size. Cameron Adams toyed with the idea as an experiment, but I’ve found few examples of this technique used on an actual production site. To that end, I’ve developed a proof-of-concept WordPress theme called Flow.
