Styling & Layout

Styling and layout are where CSS truly shines. After mastering fundamentals, the next step is understanding how to control text appearance and build multi-dimensional page layouts.

Typography & Text Styling

Good typography is the foundation of great web design. Key properties include font-family, font-size, font-weight, line-height, text-align, text-transform, and letter-spacing. Use web fonts (Google Fonts or @font-face) for custom typefaces. Always provide fallback fonts and end with a generic family like sans-serif.

The Display Property

The display property controls how an element behaves in the document flow:

• block — takes full width, starts on a new line
• inline — flows within text, only takes needed space
• inline-block — inline but accepts width/height and margins
• none — removes the element visually
• flex — creates a flex container for one-dimensional layouts
• grid — creates a grid container for two-dimensional layouts

Positioning

The position property controls element placement:

• static — normal flow (default)
• relative — offset from normal position, original space preserved
• absolute — removed from flow, positioned relative to nearest positioned ancestor
• fixed — positioned relative to viewport, stays on scroll
• sticky — hybrid that sticks at a threshold

Layout Approaches

Flexbox excels at one-dimensional layouts (rows or columns). It distributes space and aligns items along the main and cross axes.

CSS Grid handles two-dimensional layouts (rows and columns simultaneously). It provides precise control over both dimensions with features like grid-template-areas and fr units.

Responsive thinking means designing for all screen sizes. Use relative units (%, rem, vw/vh), fluid grids, and media queries to adapt layouts. Mobile-first design starts with base styles for small screens, then adds complexity at larger breakpoints.
