JavaScript is a high-level, interpreted programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS.

It enables interactive web pages and is an essential part of web applications. The vast majority of websites use it for client-side page behavior, and all major web browsers have a dedicated JavaScript engine to execute it.

Understanding CSS Flexbox

▼

CSS Flexbox (Flexible Box Layout) is a one-dimensional layout method for arranging items in rows or columns. Items flex to fill additional space or shrink to fit into smaller spaces.

Main Concepts:

  • Flex Container: The parent element with display: flex
  • Flex Items: The direct children of the flex container
  • Main Axis: The primary axis along which flex items are laid out
  • Cross Axis: The axis perpendicular to the main axis

Common Properties:

  • justify-content - Aligns items along the main axis
  • align-items - Aligns items along the cross axis
  • flex-direction - Defines the direction of the main axis
  • flex-wrap - Controls whether items wrap to new lines

Flexbox makes it much easier to design flexible responsive layout structures without using float or positioning.
