Create A Resposive Grid with CSS Flexbox
2 min read

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:
