A CSS Multi-column Layout Tutorial for Beginners

Share this article

Reading very long lines of text can be problematic for some people. They will have to focus more on not missing a line instead of the text itself. This problem is easily solved by using multiple columns to lay out the content. Multiple columns are ubiquitous in print media. The CSS Multi-column Layout Module features enable us to recreate the same kind of multi-column effect on websites.

One thing that makes it hard to use multiple columns when designing web pages is the inability to control the size of documents. In this tutorial, I will teach you how to create responsive multi-column layouts that look good on a variety of screen sizes. We will begin with the basics and then move on to more complex concepts.

Browser Support

Browser support for multi-column layout is great if you are willing to use prefixes. This feature is supported by 95.32% browsers worldwide based on stats from Can I use. A few browsers like IE10+, Edge, and Opera Mini fully support multi-column layouts. Others like Firefox and Chrome need prefixes.

There is an older polyfill available that you try if you require support for older browsers (usually this means IE9 and below). Of course, if a browser does not support multi-column features, the layout degrades gracefully to a single column layout. So a polyfill in this case might not be the best option.

The CSS multi-column layout module has a number of different properties. In the following sections I will go over all of them one by one.

Column Count and Column Width

The column-count property specifies the number of columns you want to set for an element. You can set it to auto or a positive number. When set to auto, the number of columns will be determined by the column-width property. If set to a positive number, all the columns are set to an equal width.

The column-width property specifies the width of individual columns of an element. This is not to be followed strictly. For instance, columns can be narrower if there is not enough space available. This property too can be set to both an auto value or a positive number. If set to auto, the width will be determined by the column-count property. Available space will be divided among all columns equally.

Alternatively, these two values can be set simultaneously using the shorthand columns property. The syntax for columns property would be:

.example {
  columns: <'column-width'> || <'column-count'>

A few examples of this property in use are shown below with the interpretation in the comment beside each example:

.example {
  columns: 10em;      /* column-width: 10em / column-count: auto */
  columns: 4;         /* column-width: auto / column-count: 4 */
  columns: 4 auto;    /* column-width: auto / column-count: 4 */
  columns: auto 10em; /* column-count: auto / column-width: 4 */
  columns: auto;      /* column-count: auto / column-width: auto */
  columns: auto auto; /* column-count: auto / column-width: auto */

As you can see, the first columns definition is a shorthand for what you see in the fourth, and second one is shorthand for the third. Basically, if the integer does not have any unit assigned it is parsed as column-count.

Here is a CodePen demo to demonstrate the features discussed so far

If you resize the window, you will notice a few things:

  • The column-count property always keeps the number of columns equal to the value you specify. The only thing that changes is the width of the columns.
  • The column-width property automatically changes the number of columns based on available space. The number of columns is adjusted in such a way that column width is greater than the specified value. It may also adjust the width of all columns to a smaller value if there is not enough space available.
  • The columns property uses the column-count value as the limit for maximum columns allowed. It keeps adjusting the width in such a way that column-count never exceeds the count limit and column-width is also in close proximity to the specified width.

Column Gap and Column Rule

The column-gap property allows us to specify the amount of space between columns. You can set it to normal or a length value. It can be zero but not negative. When you set it to normal, it uses the browser-defined default spacing between the columns.

The column-rule property is a shorthand that enables us to add a line between columns. This is similar to using the border-left or border-right properties. This property follows the syntax:

.example {
  column-rule: <'column-rule-width'> || <'column-rule-style'> || <'column-rule-color'>

For column-rule-width, you can specify the width as a length like 3px or use a keyword like thin, medium, or thick. column-rule-style accepts values like dashed, dotted, solid, etc. You can use all the valid values of the border-style property with column-rule-style and column-rule-color can be any valid color value.

Here is a CodePen demo with these properties used together

Column Fill and Column Span

The column-fill property determines how the content is to be partitioned to fill various columns. This property can be set to auto or balance. When set to auto, the columns are filled sequentially. Using balance makes sure that the content is divided equally between all the columns.

One thing worth keeping in mind is that, if you set a fixed height on a columned element, Firefox automatically balances the content. Other browsers, however, start filling the columns sequentially.

The column-span property controls how an element spans across multiple columns. It has two possible values: all or none. When set to all, the element spans across all columns. This property is not supported in Firefox.

Here is a CodePen demo that “spans” a blockquote element across all columns

In Firefox, the blockquote ends up in the middle column, which might be an acceptable fallback.

Creating Responsive Layouts with Multiple Columns

Now that you are up to speed on the different properties and possible values, let’s focus on keeping our layout responsive as well as user friendly.

Both column-count and column-width have their own issues. While column-count keeps the number of columns in check on larger devices, the layout will break on smaller ones. Similarly, column-width will make sure that the columns are not too narrow on smaller devices but result in lots of columns on larger ones.

To make sure your layout looks good on all screen sizes, you should specify both column-count and column-width. This way you can keep the width and number of columns under control. You might still need to fix a few issues, however, which we will discuss next.

Fixing Horizontal Scrolling

If you specify a fixed height for your columns, making the viewport narrower will result in a horizontal scrollbar. Since the content cannot expand vertically, it will grow horizontally. To fix this, you can resize your browser to know the width when horizontal scrollbars first appear. Then, you use media queries to set the height of columns to auto below that width. Here is the code to do so:

.responsive-height {
  height: 250px;

@media (max-width: 1040px) {
  .responsive-height {
    height: auto;

This CodePen demo shows both the problem and possible solution

Resize the window to see how both examples respond.

Fixing Very Long Columns

If your columns are too long, it will be an annoyance for users to keep scrolling up and down to read all the content. When the height of columns becomes greater than the viewport height itself, it is a good idea to get rid of multiple columns. This can be achieved again using media queries:

@media (min-width: 800px) {
  .long-columns {
    columns: 3 200px;

In this case, I am using multiple columns only when the viewport width is such that users no longer have to scroll up and down.

I hope this introduction to CSS’s multi-column layout module has made you familiar with this feature. These properties can be a nice addition to your responsive design toolbox, and if you are still required to support older browsers, multiple columns usually degrade gracefully to a single column.

Frequently Asked Questions on CSS Multi-Column Layout

How can I create a multi-column layout in CSS?

Creating a multi-column layout in CSS is quite straightforward. You can use the ‘column-count’ property to specify the number of columns you want in your layout. For instance, if you want three columns, you would write:

.container {
column-count: 3;

In this example, ‘.container’ is the class of the element you want to divide into columns. The ‘column-count’ property will automatically divide the content of the element into the specified number of columns.

How can I control the gap between columns in CSS?

The ‘column-gap’ property allows you to control the space between columns. The value you set for this property will be the width of the gap. For example, if you want a 20px gap between your columns, you would write:

.container {
column-gap: 20px;

Can I create columns of different widths in CSS?

Unfortunately, the CSS multi-column layout module does not support columns of different widths. All columns created using the ‘column-count’ property will have equal widths. However, you can create columns of different widths using other CSS techniques such as Flexbox or Grid.

How can I control the column width in CSS?

You can control the column width using the ‘column-width’ property. This property specifies the optimal width of the columns, but the browser will adjust the width to fit the content if necessary. For example, to set the column width to 200px, you would write:

.container {
column-width: 200px;

How can I create a column rule in CSS?

The ‘column-rule’ property allows you to create a rule or line between columns. You can specify the width, style, and color of the rule. For example, to create a 1px solid black rule, you would write:

.container {
column-rule: 1px solid black;

How can I control the column break in CSS?

The ‘break-inside’ property allows you to control column breaks. You can set this property to ‘avoid’ to prevent breaks within an element. For example:

.element {
break-inside: avoid;

Can I use multi-column layout with responsive design?

Yes, you can use multi-column layout with responsive design. You can use media queries to adjust the number of columns based on the viewport width. For example, you might want to display one column on small screens and three columns on large screens.

How can I fill columns in CSS?

By default, columns are filled sequentially. This means that the first column is filled first, then the second, and so on. However, you can change this behavior using the ‘column-fill’ property. If you set this property to ‘balance’, the browser will try to fill the columns evenly.

How can I span columns in CSS?

The ‘column-span’ property allows an element to span across multiple columns. You can set this property to ‘all’ to make an element span all columns. For example:

.element {
column-span: all;

Are there any browser compatibility issues with CSS multi-column layout?

Most modern browsers support CSS multi-column layout, but there may be some differences in implementation. It’s always a good idea to test your layout in different browsers to ensure it works as expected. You can also use tools like Can I Use to check browser support for different CSS properties.
