A column is a vertical division in a document or webpage layout that is typically used to organize and present content in a structured manner.

Columns are commonly used in multi-column layouts to arrange text, images, videos, or other elements side by side, allowing for efficient use of space and improved readability. They enable the content to be divided into distinct sections, making it easier for users to navigate and locate specific information.

In HTML, columns can be created using CSS properties such as “float”, “flexbox”, or “grid”. The number of columns, their width, spacing, and other styling attributes can be adjusted to suit the desired layout.
