🙋 Introduction

The content property in CSS is used with the ::before and ::after pseudo-elements to insert generated content into an element.

This property is particularly useful for adding decorative content or for inserting content that is purely presentational, without having to alter the HTML markup.

💡 Syntax

The syntax for the content property is quite flexible and can include text, images, counters, and even combinations of these.

Syntax

Copied

selector::before {
  content: "text" | url(image) | counter(name) | attr(attribute) | open-quote | close-quote | no-open-quote | no-close-quote | normal | none;
}

🎛️ Default Value

The default value of the content property is normal, which means no content is generated.
