CSS Shapes: Fundamentals

August 20, 2024

CSS Shapes solve a fundamental web layout limitation: content wrapping around custom shapes. Before CSS Shapes, floated elements always created rectangular float areas, preventing content from flowing around circles, polygons, or transparent images. This tutorial explains what CSS Shapes are, how they control content flow without rendering visual shapes, and the core concepts needed to use them effectively.

CSS Shapes: What are They?

August 19, 2024

CSS Shapes control how content flows around floated elements, but they don't actually render visual shapes—they define float areas. Understanding this distinction is crucial: CSS Shapes determine where content wraps, not what shapes appear on the page. This tutorial explains what CSS Shapes are, how they differ from visual CSS shapes created with borders or clip-path, and why floated elements still create rectangular float areas without the CSS Shapes module.

CSS Shapes: Introduction

August 19, 2024

Web layouts have been trapped in rectangular boxes for decades, limiting designers to grid-based structures that can't match the creative freedom of print design. CSS Shapes changes everything by allowing content to flow around custom shapes, creating magazine-style layouts with text wrapping around circles, polygons, and custom paths. This comprehensive guide teaches you how to break free from rectangular constraints and build sophisticated, editorial-style layouts that were previously impossible on the web.

Angular Angular Effects Angular Signals

Angular effect(): React to Signal Changes with Side Effects (v19+)

August 01, 2024

Reacting to signal changes for side effects like logging, API calls, or DOM manipulation requires a different approach than computed signals, which are read-only and template-focused. Angular's effect() function executes code when signals change, making it perfect for debugging, analytics, and imperative operations that can't be handled in templates. This tutorial demonstrates when and how to use effect() effectively, while also covering when NOT to use it (see the linked tutorial for common mistakes).
