Introduction

CSS (Cascading Style Sheets) is a language used for describing the presentation of a document written in HTML. It is one of the core technologies for building web pages and is essential for styling your web applications.

Basic CSS Selectors

CSS selectors are used to target elements on a webpage. Here are some common selectors:

  • Element Selectors: Selects elements by their tag name, e.g., h1 for all <h1> elements.
  • Class Selectors: Selects elements by their class attribute, e.g., .class-name for all elements with the class class-name.
  • ID Selectors: Selects a single element by its ID, e.g., #id-name for the element with the ID id-name.

Box Model

The Box Model describes the rectangular box that is the fundamental unit of layout in CSS. Each element is represented as a box with four main components: margin, border, padding, and content.

  • Flexbox: A one-dimensional layout model for complex layouts.
