Understanding the Basics of CSS

Welcome to the foundation of Cascading Style Sheets (CSS), where the alchemy of design takes shape. Let’s delve deeper into the core elements that wield the magic of web styling:

Selectors: Identify HTML elements to style.

Selectors can be element names, classes, IDs, attributes, or combinations thereof.
Properties and Values: Define the appearance and behavior of selected elements.

Properties specify the aspect to style (e.g., color, font-size, margin).
Values determine how properties should be applied (e.g., red, 16px, 10%).
Declaration Blocks: Group properties and values within curly braces {}.

Declarations end with semicolons ;.
Selectors and Declarations: Together form CSS rules.

Rules consist of a selector followed by one or more declarations.
Comments: Provide explanations or notes within CSS files.
