By the end of this article, you will have a better understanding of how to create flexible and responsive layouts that align flexbox columns to meet your design needs.
Creating Flexbox Columns
To create flexbox columns, you need to use the flexbox layout system in CSS. Here are the steps to create a flexbox column −
Create a parent container for the columns.
Set the display property to "flex" for the parent container.
Create child elements for the columns.
Use flexbox properties to style the columns.
Example
Given below example illustrates on how to create flexbox columns.
<!DOCTYPE html>
<html>
<head>
<style>
.flex-container {
display: flex;
background-color: cyan;
height: 200px;
width: 80%;
}
.flex-item {
flex-basis: 33%;
background-color: red;
width: 50px;
margin: 30px;
text-align: center;
letter-spacing: 1px;
}
</style>
</head>
<body>
<h1>Flexbox Columns</h1>
<div class="flex-container">
<div class="flex-item"> Column 1 </div>
<div class="flex-item"> Column 2 </div>
<div class="flex-item"> Column 3 </div>
<div class="flex-item"> Column 4 </div>
</div>
</body>
</html>
Methods to Align Flexbox Columns Left and Right
Aligning flexbox columns left and right using CSS can be achieved through a variety of techniques. Here are some of the most effective methods −
To align columns to the left, set the "align-content" property of the flex container to "flex-start". This property aligns the content to the left side of the container.
Example
The following example demonstrates aligning a flexbox column to the left.
<!DOCTYPE html>
<html>
<head>
<style>
.flex-container {
display: flex;
background-color: cyan;
height: 200px;
width: 100%;
flex-flow: column wrap;
align-content: flex-start;
}
.flex-item {
flex-basis: 20%;
background-color: red;
width: 100px;
margin: 30px;
text-align: center;
letter-spacing: 1px;
}
</style>
</head>
<body>
<h1>Flexbox Columns</h1>
<div class="flex-container">
<div class="flex-item"> Column 1 </div>
<div class="flex-item"> Column 2 </div>
<div class="flex-item"> Column 3 </div>
<div class="flex-item"> Column 4 </div>
<div class="flex-item"> Column 5 </div>
<div class="flex-item"> Column 6 </div>
<div class="flex-item"> Column 7 </div>
<div class="flex-item"> Column 8 </div>
</div>
</body>
</html>
Aligning Right
To align columns to the right, set the "align-content" property of the flex container to "flex-end". This property aligns the content to the right side of the container.
CSS Example
.flex-container {
display: flex;
background-color: cyan;
height: 200px;
width: 100%;
flex-flow: column wrap;
align-content: flex-end;
}
.flex-item {
flex-basis: 20%;
background-color: red;
width: 100px;
margin: 30px;
text-align: center;
letter-spacing: 1px;
}
Use Margin Auto
To align the column to the left, set the "margin-right" property of the last flex item to "auto". This will push the item to the left side of the container.
Example
To align columns to the right, set the "margin-left" property of the first flex item to "auto". This will push the item to the right side of the container.
<!DOCTYPE html>
<html>
<head>
<style>
.container {
display: flex;
}
.column {
background-color: orange;
margin: 10px;
width: 100px;
height: 40px;
text-align: center;
letter-spacing: 1px;
padding: 2px;
}
.column:last-child {
margin-right: auto;
}
</style>
</head>
<body>
<div class="container">
<div class="column"> Column 1 </div>
<div class="column"> Column 2 </div>
<div class="column"> Column 3 </div>
<div class="column"> Column 4 </div>
<div class="column"> Column 5 </div>
</div>
</body>
</html>
Align left and right simultaneously
Till now we have aligned the columns towards left or right of the flex container. Now, let’s align them to both left and right simultaneously.
To align columns to the left and right, set the "align-content" property of the flex container to "space-between". This property aligns the content to the left as well as right side of the container.
Example
The following example demonstrates aligning flexbox columns towards left and right.
<!DOCTYPE html>
<html>
<head>
<style>
.flex-container {
display: flex;
background-color: cyan;
height: 200px;
width: 100%;
flex-flow: column wrap;
align-content: space-between;
}
.flex-item {
flex-basis: 20%;
background-color: red;
width: 100px;
text-align: center;
letter-spacing: 1px;
}
</style>
</head>
<body>
<div class="flex-container">
<div class="flex-item"> Column 1 </div>
<div class="flex-item"> Column 2 </div>
<div class="flex-item"> Column 3 </div>
<div class="flex-item"> Column 4 </div>
<div class="flex-item"> Column 5 </div>
<div class="flex-item"> Column 6 </div>
<div class="flex-item"> Column 7 </div>
<div class="flex-item"> Column 8 </div>
<div class="flex-item"> Column 9 </div>
<div class="flex-item"> Column 10 </div>
</div>
</body>
</html>
In the above example, the "align-content" property is set to "space-between", which creates equal spacing between columns.
