CSS subgrid is super good

CSS subgrid makes complex CMS-driven layouts much easier to implement. Using a named-line grid on a `<main>` element, child elements can break out to full viewport width or a boxed margin style with a single class, then re-align their inner content back to the readable column using `grid-template-columns: subgrid`. The technique avoids negative margins and repetitive wrapper divs, and works well with WordPress block editor or ACF flexible content output. A CodePen demo shows a two-column variant where text edges align while an image covers the full available space.
