black flag

codepoints: 1F3F4

Copy and paste black flag emoji

	Name	Emoji	Code Point
1	black flag	🏴	U+1F3F4

You can paste the chosen Emoji

Another option is to use the codepoint of the Emoji and replacing (U+) with (&#x).

You need to use the ::before or ::after pseudo-element coupled with the content property where you paste the Emoji as the value.

.element::before{

content: "🏴"

}

Another option is to use codepoint replacing (U+) with (\0).

.element::before{

content: "\01F3F4"

}

Paste the Emoji in the innerHTML value

document.querySelector(".element ").innerHTML = "🏴";

Or use the String method fromCodePoint mixed with the codepoint value where you replace (U+) with (0x).

document.querySelector(".element ").innerHTML = String.fromCodePoint(0x1F3F4);
