CSS Layouts That Don’t Break

CSS (Cascading Style Sheets) controls how your HTML looks. Fonts, colors, spacing, layout, animations — all of that is CSS. The problem many beginners face is layouts that break when the screen size changes. Modern CSS layout is built around two powerful tools: Flexbox and CSS Grid. Flexbox is great for one-dimensional layouts, like navbars or rows of cards. CSS Grid is better for two-dimensional layouts, like full page sections or dashboard grids. When to use Flexbox: - Centering content horizontally and vertically - Building navbars with logo on the left and links on the right - Simple card rows that wrap on smaller screens When to use Grid: - Complex page layouts with headers, sidebars, and content - Responsive grids that change the number of columns per breakpoint - Landing sections where text and image need to align in a clean grid Example mental model: Use Flexbox for aligning items in a row or column. Use Grid for designing the page skeleton. Combine both for best results. Always test your designs on mobile, tablet, and desktop breakpoints.
