The <div> element is a block-level element by default, which means it occupies the full available width and automatically adds a line break before and after it.
The <div> element is often used to group sections of a web page together.
You can have many <div> containers on the same page.
Although the CSS float property wasn't initially designed to place <div> elements side-by-side, it has long been used for that purpose.
The float property in CSS helps position and format content by enabling elements to be arranged horizontally instead of stacking vertically.
If you change the <div> element's display property from block to inline-block, the <div> elements will no longer add a line break before and after, and will be displayed side by side instead of on top of each other.
The CSS Flexbox Layout Module was introducd to make it easier to design flexible responsive layout structure without using float or positioning.
To make the CSS flex method work, surround the <div> elements with another <div> element and give it the status as a flex container.
he CSS Grid Layout Module provides a grid-based system with rows and columns, making it simpler to create web layouts without relying on floats or manual positioning. While it may seem similar to Flexbox, CSS Grid allows you to define multiple rows and control the layout of each row independently. To use CSS Grid, the <div> elements must be wrapped inside a parent <div> set as a grid container, where you define the number and width of the columns.
