This article explains the CSS gap property - shorthand for row-gap and column-gap - and how to use it in Grid and modern Flexbox to create consistent spacing between items. It includes code examples, a responsive gallery, tips for differing row/column gaps, enabling flex-wrap, and choosing units, helping you maintain uniform, visually tidy layouts across screen sizes.
CSS box-sizing dictates how element width/height are computed relative to content, padding, and borders. content-box (default) sizes only content, expanding total size with padding/border; border-box includes padding/border within set dimensions for predictable layouts. The article shows examples, highlights benefits for responsive design, grids, and components, and advises using border-box globally with mindful exceptions and CSS variables.
Using tables for layout purposes is a bad idea due to accessibility issues, loss of semantic meaning, inflexibility, and maintenance difficulties. Modern web development relies on CSS-based layouts using elements like `div`, `span`, and `header`. Alternatives include grid systems, Flexbox, and CSS Grid, which provide flexible and semantic ways to create complex layouts without resorting to tables.
