Flex Responsive

Responsive Flexbox

You learned from the CSS Media Queries chapter that you can use media queries to create different layouts for different screen sizes and devices.

For example, if you want to create a three-column layout for large screen sizes, and a one-column layout for small screen sizes (such as phones), you can change the flex-direction from row to column at a specific breakpoint (600px in the example below):

Example

  .flex-container {
  display: flex;
  flex-direction: row;
}

  .flex-item {
  background-color: #f1f1f1;
  padding: 10px;

  font-size: 30px;
  text-align: center;
  width: 100%;
}

/*
  Make a one column-layout instead of three-column layout */
@media
  (max-width: 600px) {
  .flex-container {

  flex-direction: column;
  }
}

Another way is to change the percentage of the flex property of the flex items to create different layouts for different screen sizes. Note that we also have to include flex-wrap: wrap; on the flex container for this example to work:

Example

  .flex-container {
  display: flex;
  flex-wrap: wrap;
}

.flex-item
  {
  background-color: #f1f1f1;
  padding: 10px;

  text-align: center;
  font-size: 30px;
  flex: 33.3%;
}

/*
  Make a one
  column-layout instead of a three-column layout */
@media (max-width: 600px)
  {
  .flex-item {
    flex: 100%;
  }
}
