Create A Resposive Grid with CSS Flexbox

Even though CSS Grid is more or less designed to create grids with, flexbox can actually be used to create some responsible grids without much effort.

Creating the flex wrapper

First of all, we need to create the flex wrapper. We only need some basic css properties. Most important is the flex-wrap property, which will allow the items to wrap if they overflow. I’ll add gap as well to add some nice spacing.

.wrapper {
    display: flex;
    flex-wrap: wrap;
    gap: 16px;

Creating the items

The items only need two properties to create a responsive effect; min-width and flex.

.item {
    min-width: 250px;
    flex: 1;

The min-width is needed to put some restrictions on the items, not making them smaller than the specified width. Setting flex to 1, which is shorthand for flex: 1 1 0%, actually does three things.

  • Setting flex-grow to 1, allowing the item to grow if needed.
  • Setting flex-shrink to 1, allowing the item to shrink if needed. However, as we have defined a min-width, it won’t be smaller than that.
  • Setting flex-basis to 0%, which will set the “ideal” size for the item.

Here is an example of how it looks:
