gap property. The gap property can be used to set the spacing between elements, creating a more aesthetically pleasing web page layout.
What is CSS Flex Layout?
In traditional CSS layout, we typically use properties like float and positioning to achieve page layout. In Flex layout, however, the display: flex property allows for simpler and more intuitive page layouts. Flex containers automatically arrange child elements in a row or column, and a series of properties can be used to control the arrangement, size, and position of elements.
How to use CSS Flex Layout
To use Flex layout, first set the container element’s display property to flex. Then, control the layout by setting related properties of the container element, such as flex-direction, justify-content, and align-items.
The following is a simple example code showing how to use Flex layout to implement page layout:
<!DOCTYPE html>
<html>
<head>
<title>Flex Layout Example</title>
<style>
.container {
display: flex;
justify-content: center;
align-items: center;
height: 300px;
border: 1px solid #000;
}
.box {
width: 100px;
height: 100px;
background-color: red;
margin: 10px;
}
</style>
</head>
<body>
<div class="container">
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
</div>
</body>
</html>
In the example code above, we create a flex container .container and set justify-content: </p> property in Flex Layout can be used to set the spacing between elements. In the previous code examples, we achieved spacing by setting the

gap property sets both row and column spacing, using a single value. For example, gap: 10px sets both row and column spacing to 10px, while gap: 10px 20px sets both row spacing to 10px and column spacing to 20px.
Here’s a sample code showing how to use the gap attribute to set the spacing between elements:
<!DOCTYPE html>
<html>
<head>
<title>Flex Layout Example</title>
<style>
.container {
display: flex;
justify-content: center;
align-items: center;
height: 300px;
border: 1px solid #000;
gap: 20px;
}
.box {
width: 100px;
height: 100px;
background-color: red;
}
</style>
</head>
<body>
<div class="container">
<div class="box"></div>
<div class="box"></div>
<div class="box"></div> </div>
</body>
</html>
Running the above code, you’ll see a 20px gap between the three red boxes. This is achieved by setting gap: 20px. Furthermore, the justify-content and align-items properties still help center the items.
