CSS Relative Positioning: Real-World Examples and Use Cases

📚 Quick Study Guide

• 📍 Relative Positioning: An element is positioned relative to its normal position.
• 📐 Offset Properties: Use `top`, `right`, `bottom`, and `left` to adjust the element's position.
• ✨ No Impact on Flow: Relative positioning does not affect the position of other elements in the document flow.
• 🔄 Stacking Context: Relatively positioned elements can overlap other elements depending on the `z-index`.
• 💡 Use Case: Fine-tuning the placement of elements without disrupting the overall layout.
