The multi-column column-rule property is used to specify the number of rules.
You can try to run the following code to implement the column-rule property in CSS3 −
Example
<html>
<head>
<style>
.multi {
/* Column count property */
-webkit-column-count: 4;
-moz-column-count: 4;
column-count: 4;
/* Column gap property */
-webkit-column-gap: 40px;
-moz-column-gap: 40px;
column-gap: 40px;
/* Column style property */
column-rule: 4px solid #ff00ff;
}
</style>
</head>
<body>
<div class = "multi">
Tutorials Point originated from the idea that there exists a class of readers who respond
better to online content and prefer to learn new skills at their own pace from the comforts
of their drawing rooms. The journey commenced with a single tutorial on HTML in 2006 and
elated by the response it generated, we worked our way to adding fresh tutorials to our
repository which now proudly flaunts a wealth of tutorials and allied articles on topics
ranging from programming languages to web designing to academics and much more.
