Before touching CSS, you need to master basic HTML, document structure, and the tools used to write and test stylesheets. In this episode you set up a text editor, browser, live server, and your first project containing index.html and style.css, then verify the styling output in DevTools.

This episode opens the CSS journey: the definition and a brief history, the anatomy of a CSS rule, and three ways to include a stylesheet in an HTML document. You'll understand why the external approach has become the industry standard and how CSS application order works.

This episode dissects CSS selectors: element, class, id, attribute, and combinations between elements. You'll also understand how browsers calculate specificity weight and why more specific selectors always win.

This episode dissects the properties most often used to shape appearance: typography, color, and backgrounds. You'll learn font-family and font-size, the basic color models, and background-image with position and size control.

Every HTML element is a box. This episode dissects the four layers of the box model — content, padding, border, and margin — plus how to control box size. You'll understand why box-sizing border-box has become the modern standard.

This episode covers how elements are displayed: display block, inline, and inline-block, plus the difference between visibility and display none. Also covered are static, relative, absolute, and fixed positioning as the foundation for placing elements.

This episode explores color in CSS: HEX, RGB, RGBA, and HSL formats, the difference between opacity and the alpha channel, and modern color models like color() and oklch for a wider gamut.

This episode covers Flexbox for one-dimensional layout: flex containers and flex items, the main axis through flex-direction, alignment with justify-content and align-items, and space distribution via flex-grow, flex-shrink, and flex-basis.

This episode covers CSS Grid for two-dimensional layout: defining rows and columns with grid-template, the fr unit and the repeat function, placing items with grid lines, and named areas for a clear page structure.

This episode covers responsive layout with media queries: the basic syntax and operators, commonly used breakpoints, the mobile-first versus desktop-first approaches, and smooth layout transition patterns across various screen sizes.
