CSS Responsive

CSS Grid

CSS Flex-Responsive

Responsive Flexbox

Media queries can be used to create different layouts for different screen sizes and devices.

HTML
				
					<p>The "flex-direction: row;" stacks the flex items horizontally (from left to right).</p>
<p>The "flex-direction: column;" stacks the flex items vertically (from top to bottom).</p>
<p><b>Resize the browser window to see that the direction changes when the 
screen size is 800px wide or smaller.</b></p>

<div class="flex-container">
  <div class="flex-item-left">1</div>
  <div class="flex-item-right">2</div>
</div>

				
			
CSS
				
					* {
  box-sizing: border-box;
}

.flex-container {
  display: flex;
  flex-direction: row;
  font-size: 30px;
  text-align: center;
}

.flex-item-left {
  background-color: #f1f1f1;
  padding: 10px;
  flex: 50%;
}

.flex-item-right {
  background-color: dodgerblue;
  padding: 10px;
  flex: 50%;
}

/* Responsive layout - makes a one column-layout instead of two-column layout */
@media (max-width: 800px) {
  .flex-container {
    flex-direction: column;
  }
}
				
			

Output

The "flex-direction: row;" stacks the flex items horizontally (from left to right).

The "flex-direction: column;" stacks the flex items vertically (from top to bottom).

Resize the browser window to see that the direction changes when the screen size is 800px wide or smaller.

Another method is by changing the percentage of the flex property of the flex items to make different layouts for different screen sizes. The flex-wrap: wrap; needs to be included on the flex container for this example to work:

HTML
				
					<p>In this example, we change the percentage of flex to create different layouts for different screen sizes.</p>
<p><b>Resize the browser window to see that the direction changes when the 
screen size is 800px wide or smaller.</b></p>

<div class="flex-container">
  <div class="flex-item-left">1</div>
  <div class="flex-item-right">2</div>
</div>
				
			
CSS
				
					* {
  box-sizing: border-box;
}

.flex-container {
  display: flex;
  flex-wrap: wrap;
  font-size: 30px;
  text-align: center;
}

.flex-item-left {
  background-color: #f1f1f1;
  padding: 10px;
  flex: 50%;
}

.flex-item-right {
  background-color: dodgerblue;
  padding: 10px;
  flex: 50%;
}

/* Responsive layout - makes a one column-layout instead of a two-column layout */
@media (max-width: 800px) {
  .flex-item-right, .flex-item-left {
    flex: 100%;
  }
}
				
			

Output

In this example, we change the percentage of flex to create different layouts for different screen sizes.

Resize the browser window to see that the direction changes when the screen size is 800px wide or smaller.
