Bootstrap-like Responsive Grid Layout System – CSSColumnPro.css

CSSColumnPro is a CSS grid layout system based on the 12-column grid design concept. It utilizes CSS3 flexbox to provide an alternative to Bootstrap’s grid layout system.

Developers can use Bootstrap-like CSS utility classes, such as .col-sm-4, .col-lg-8, .col, etc., to generate complex, fully responsive, and highly customizable grid layouts that adapt to different screen sizes.
