> But the client side rendering isn't static, and it certainly isn't 1000:1 R:W. There are different browsers on different devices, with different resolutions, pixel densities, zoom-levels, minimum font sizes, window-sizes and orientations. Yeees, and? Response CSS designs solve a lot of that with zero server-side computation overhead, and (compared to JS templating/render engines) minimal client-side overhead.
