Margin is the easiest to understand. Adding margin to an element creates space outside of it, pushing it away from other elements. Padding adds space between the edge of the element and its content. By adding padding, you ensure that regardless of the element's content, there is always consistent spacing inside.

Gap is a newer property that allows you to create space between elements within a flexbox or grid container. It's super handy, but not always the best choice for every scenario. Real projects are more nuanced, and knowing when to use margin over gap, or padding over margin, is key.

I'll walk you through a realistic example to show how to choose the right CSS spacing property. We'll start with a layout that needs spacing adjustments, and by the end, you'll know exactly how to pick the right property for each use case. CodePens are provided so you can practice along.

We'll fix spacing issues by adding consistent site gutters using padding, ensuring vertical spacing in the header and footer, and deciding between margin and gap for different components. I'll explain why I prefer certain approaches, and you'll learn tips like using the lobotomized owl selector for better vertical rhythm and enhancing navigation accessibility with padding.

By the end of this video, you'll have a clear understanding of how to use margin, padding, and gap in CSS to create well-spaced, professional layouts. Whether you're a beginner or looking to refine your skills, this tutorial will provide practical insights and techniques to enhance your CSS proficiency.
