The Web is more than pixels

I’m a big, big believer of matching breakpoints to the design, not to individual devices. If we’re after more future-proof responsive designs, we should stop thinking in terms of “320px,” “480px,” “768px,” or whatever — the Web’s so much more flexible than that, and those pixels are a snapshot of the Web as we know it today. Instead, we should focus on breakpoints tailored to the design we’re working on.
