The "content" property in CSS

Where in CSS, the "content" property is used?

The `content` property in CSS is used to insert content before or after an element's content, typically using the `::before` and `::after` pseudo-elements. 

This property is often used for adding decorative elements or textual annotations to HTML elements.

Syntax of the `content` property:

/* Insert content before an element's content */
::before {
    content: "content here";
}

/* Insert content after an element's content */
::after {
    content: "content here";
}

CSS

The type of content that can be inserted

You can insert text, images, icons, or other HTML elements using the `content` property.

Inserting text

Here's an example of how you can use `content` to insert text before and after an element:

/* Insert text before and after an element */
p::before {
    content: "Start: ";
}

p::after {
    content: " :End";
}

CSS

In this example, the text "Start: " will be inserted before each `<p>` element's content, and " :End" will be inserted after each `<p>` element's content.

Inserting icons

Here's how you can use `content` to insert an icon after a link:

/* Insert an icon after a link */
a::after {
    content: url('icon.png');
}

CSS

In this example, an image icon named 'icon.png' will be inserted after each `<a>` (link) element.

Inserting HTML elements

You can also use `content` to insert HTML elements:

/* Insert a clickable button after a paragraph */
p::after {
    content: "<button>Click Me</button>";
}

CSS

In this example, a clickable button element will be inserted after each `<p>` element.

The content property can be used only with...

Keep in mind that the `content` property can only be used with the `::before` and `::after` pseudo-elements, and it only affects the visual rendering of the element, not its actual content in the HTML document.
