As web developers, we often encounter the need to create card components. whether it's for a product/project showcase, user profile, or blog post, cards are everywhere.
In the past, creating responsive layouts was a challenge. The creation of these designs has become significantly simpler and more intuitive due to the advent of modern CSS techniques, specifically CSS Flexbox.
Flexbox simplifies the process of creating responsive layouts. We can easily arrange, align, and space items in a container without using complex media queries. This means we can build layouts that adapt beautifully to different screen sizes and orientations without specifying exact breakpoints.
The aim is to create responsive cards of equal heights without relying on breakpoints by using CSS Flexbox. We will ensure that each card maintains the same height regardless of the content length, adapting seamlessly to different screen sizes.
