CSS Flexbox

CSS Flexbox is a layout module in CSS that provides a flexible and efficient way to lay out, align, and distribute space among elements within a container. Flexbox allows items to align vertically or horizontally and can be used to build responsive and flexible web designs with ease. It provides greater layout control on web pages, allowing for dynamic and intricate designs that adjust to viewport size, making it a powerful tool for responsive web design.

Flexbox is especially useful, when it comes to designing cross references, which may vary in size or orientation of the device used. This makes it ideal for designing websites that require the layout to be perfect for both the PC as well as the mobile gadgets. With the help of Flexbox you can create the layouts of the site, which are adaptable and look good on any device. This means to cater for the accessibility of your site for people with disabilities as well as make sure that this site will look good no matter the way that it will be used.
