Často kladené otázky
Flexbox creates one-dimensional layouts: aligning items in a row or column, distributing space, and controlling alignment. It is ideal for navigation bars, card rows, button groups, and component-level layouts.
Flexbox works in one dimension at a time (row or column). CSS Grid works in two dimensions simultaneously (rows and columns). Use Flexbox for component-level layouts. Use CSS Grid for full-page layouts and complex two-dimensional arrangements. Many developers use both.
flex: 1 is shorthand for flex-grow: 1; flex-shrink: 1; flex-basis: 0%; It makes a flex item grow to fill available space equally among siblings. Use it to create equal-width columns without specifying a width.All modern browsers fully support Flexbox: Chrome, Firefox, Safari, Edge, and Opera. Over 99% of global users have a Flexbox-capable browser. IE11 has partial support with known bugs, but IE11 usage is below 0.5% globally.
