The unicode-bidi property in HTML DOM is applied along-with the direction property to determine how the bidirectional text is handled in a document.
Syntax:
unicode-bidi: normal|embed|bidi-override|isolate|isolate-override|plaintext|initial|inherit;
Property Values:
1. normal: It is the default value. The additional level of embedding does not open from the element.
Syntax:
unicode-bidi: normal;
Example:
<!DOCTYPE html>
<html>
<head>
<title>
CSS unicode-bidi Property
</title>
<!-- style for unicode-bidi property -->
<style>
.GFG {
direction: rtl;
unicode-bidi: normal;
}
</style>
</head>
<body>
<h1>GeeksforGeeks</h1>
<h2>
CSS unicode-bidi Property
</h2>
<div class = "GFG">
A computer science portal for geeks
</div>
</body>
</html>
Output:

2. embed: This value is used to open an additional level of embedding.
Syntax:
unicode-bidi:embed;
Example:
<!DOCTYPE html>

direction: rtl;
unicode-bidi: embed;
}
</style>
</head>
<body>
<h1>GeeksforGeeks</h1>
<h2>
CSS unicode-bidi Property
</h2>
<div class = "GFG">
A computer science portal for geeks
</div>
</body>
</html>
Output:

3. bidi-override: This value creates an override for inline element and in case of block element, it creates an override for inline-level descendants not within another block element.
Syntax:
unicode-bidi:bidi-override;
Example:
<!DOCTYPE html>
<html>
<head>
<title>
CSS unicode-bidi Property
</title>
<!-- style for unicode-bidi property -->
<style>
.GFG {
direction: rtl;
unicode-bidi: bidi-override;
}
</style>
</head>
<body>
<h1>GeeksforGeeks</h1>
<h2>
CSS unicode-bidi Property
</h2>
<div class = "GFG">
A computer science portal for geeks
</div>
</body>
</html>
Output:

4. initial: It sets the unicode-bidi property to its default value.
Syntax:
unicode-bidi: initial;
Example:
<!DOCTYPE html>
<html>
<head>
<title>
CSS unicode-bidi Property
</title>
<!-- style for unicode-bidi property -->
<style>
.GFG {
direction: rtl;
unicode-bidi: initial;
}

<h1>GeeksforGeeks</h1>
<h2>

Output:

5. inherit: The unicode-bidi property is inherited from its parent element.
Syntax:
unicode-bidi: inherit;
Example:
<!DOCTYPE html>

}
</style>
</head>
<body>
<h1>GeeksforGeeks</h1>
<h2>
CSS unicode-bidi Property
</h2>
<div class = "Geeks">
<div class = "GFG">
A computer science portal for geeks
</div>
</div>
</body>
</html>
Output:

6. isolate-override: It applies the isolation behavior of the isolate keyword to the surrounding content and the override behavior of the bidi-override to the inner content.
