In a vintage article dated from 2008 by the renowned John Resig, the challenges of sub-pixel rendering in older browsers were discussed. An interesting scenario was presented where 4 floated divs, each with a width of 25%, were contained within a parent div of width 50px. The dilemma arises in determining how wide each div would be. Mathematically, each div should be 12.5px wide, but due to the absence of half pixels, older browsers tended to round these values either down to 12px, up to 13px, or a combination of both.
Curiosity lingers - How do modern browsers tackle this issue 13 years later?
