Styling Apps with CSS in App Development
CSS (Cascading Style Sheets) controls the visual appearance of your app — colors, fonts, spacing, and layout.
Modern CSS uses Flexbox and Grid for creating responsive, well-aligned layouts.
CSS variables (custom properties) allow you to define reusable values like brand colors and spacing scales.
The cascade and specificity rules determine which styles are applied when multiple rules target the same element.
A consistent design system with defined colors, fonts, and spacing makes your app look professional.
