There are countless css grid options. Countless options within nearly countless approaches to the problem.
One approach that stands out from the others is ungrid - the simplest responsive css grid. I like its genius simplicity.
The css:
.container-selector {
.row { display: table; table-layout: fixed; width: 100%; }
.col { display: table-cell; }
}
| I find this approach particularly useful when I need to organize a single row of 100% width – and when, for compatibility reasons, flexbox ([A Complete Guide to Flexbox | CSS-Tricks](https://css-tricks.com/snippets/css/a-guide-to-flexbox/)) is not an option. |
