Difference between flex and grid

Dimensions define the primary demarcation between Flexbox and CSS Grid. Flexbox was designed specifically for one-dimensional layouts, while CSS Grid is engineered to enable two-dimensional layouts. Therefore, CSS Grid can easily render rows and columns simultaneously.

In layperson’s terms, CSS Grid presents a larger canvas, while Flexbox offers minute functionality that operates in a restricted space. The grids have been designed for a two-dimensional organization.

However, the two specifications share some common points, and if you know how to use flexible boxes, you will find some concepts that will help you to grasp CSS grids. In this article, we’ll go through the main differences between Grid and Flexbox, summarized as follows:

Flexbox is designed for one-dimensional layouts, and Grid for two-dimensional layouts.
The approach of CSS Grid is the layout first, while the Flexbox approach is primarily the content.
The Flexbox layout is best suited to application components and small-scale layouts, while the Grid layout is designed for larger-scale layouts that are not linear in design.

Getting to know Flexbox and Grid

The one-dimensional Flexbox

CSS Flexible Box Layout (or Flexbox) allows designers to position responsive elements appropriately within screens of different sizes. The tools include:

box layout for documents, an inline layout for defining the appearance of text on screens, a table layout to depict tabular data in one dimension, and a positioned layout mode that enables explicit positioning of responsive elements. Flexbox is popular among front-end developers, since it allows developers to create multiple instances of dynamic layouts and effortlessly align content within containers.

The flexible box module has been designed as a one-dimensional presentation model and as a method that can provide space distribution between interface elements and powerful alignment functions. When we describe the flexbox as one-dimensional, we describe the fact that flexbox processes layouts in one dimension at a time, as a row or column. This can be compared to the two-dimensional model of the CSS grid layout, which controls columns and rows together.
