Based on Flexbox (CSS Flexible Box Layout Module), Gridlex is a very simple css grid system to quickly create modern layouts and submodules. The concept is simple: you need to wrap your .col in a .grid. That’s all.
Basically each column is the same width as every other cell in the grid, but you can add sizing classes to individual columns. Grids can be nested. Always. Directly in a column and for responsive designs, you can add classes based on media-queries.
