Learn CSS Flexbox with online courses and programs

Flexbox is a flexible box layout that enables web designers to build and organize website layouts using a simple set of CSS rules. Advance your web developer skills and discover the benefits when you learn Flexbox.

What is the Flexbox Layout module?

The CSS Flexbox (flexible box) Layout module is a one-dimensional web layout module that simplifies the creation of CSS layouts. Web developers can use flexbox to achieve complex and responsive structures without using techniques like positioning or floats.

Flexbox controls the layout based on a row or column, one direction at a time. It provides complete control of the alignment, movement, order, and size of document elements. The module enables users to lay out, align, and distribute space, even when the size or viewport of the components is unknown or dynamic.

The Flexbox container can change its elements’ height and width to fill the available free space best and shrink them to prevent an overflow. This capability makes Flexbox an ideal mobile and responsive design solution, enabling website users to see all the website elements clearly on whatever device they’re using in any browser.^{Footnote 1}

Responsive design enables websites to work in a user-friendly way across a variety of browsers and devices.

What is the difference between CSS Grid and Flexbox?

CSS Grid and Flexbox are both layout models. The main difference is that while Flexbox creates one-dimensional layouts using one axis, CSS Grid enables the creation of two-dimensional layouts. In CSS Grid, you can place components on both the X-axis and Y-axis, which gives you more control over the visual organization of a website. You can use CSS Grid and Flexbox separately or together by using a Flexbox container inside a CSS Grid container.^{Footnote 4}

Which is better: Flexbox or Bootstrap?

Bootstrap is an open-source CSS framework that enables developers to build responsive websites that provide a convenient user experience on any device in any browser.

Bootstrap 4’s grid system is built with Flexbox so that web developers can use the Bootstrap framework and the implementation of Flexbox together in their projects.^{Footnote 5}
