Responsive strategies in CSS

The goal of responsive web design is for websites to look good on every device, whether it is a mobile phone, tablet, or desktop computer. To achieve this, different strategies are applied, such as flexible grids, fluid layouts, and media queries.

Using media queries

With media queries, CSS rules can be adjusted to different screen sizes. For example, different styles can be applied to screens under 768px than on larger displays.

In this example, the text size changes depending on the screen width.

Fluid layouts and containers

Fluid layouts use percentage widths or maximum widths for content, so it always adapts to the screen size. A container centers and structures the content.

In this example, the content always stays centered while flexibly adjusting to different screen sizes.

Tips for responsive strategies

When applying responsive design, readability, performance, and accessibility should always be considered.

• Use a mobile-first approach, optimizing for smaller screens first, then scaling up.
• Test the site on different devices and browsers to ensure it works everywhere.
• Avoid excessive use of fixed pixel values, prefer relative units and percentages instead.
