CSS Concepts for Modern Web Development

Course Description

Formerly "Designing with Cascading Style Sheets: Advanced."

This course introduces Cascading Style Sheets (CSS) concepts that underpin modern, responsive, and accessible user interfaces. Students learn how CSS is used to create layouts that adapt seamlessly across mobile, tablet, laptop, and desktop devices while following current front-end development best practices.

Through lectures and hands-on exercises, you'll explore responsive design, Flexbox, CSS Grid, media queries, typography, forms, animations, accessibility, browser compatibility, and debugging with browser developer tools.

The course also examines how CSS is used within modern front-end frameworks. Rather than focusing solely on traditional HTML and CSS pages, you'll learn how styling is applied to React components using JSX and gain an introduction to TypeScript and component-based development. You'll also explore the role of design systems, reusable UI components, and consistent styling patterns used in professional web applications.

In addition, you'll learn how AI-powered development tools such as Lovable, v0, and other LLM coding assistants generate React-based user interfaces. The course emphasizes understanding the concepts needed to guide these tools effectively-writing better prompts, evaluating generated code, debugging layouts, and refining AI-generated interfaces into maintainable, responsive, and accessible applications.

By the end of the course, you'll understand the CSS, React, component, and design system concepts that enable you to work effectively with both modern front-end frameworks and AI-assisted development tools.
