The selection.html() function is used to set the inner HTML on all the selected elements. If the value is constant then all the elements are given same value. A null value will clear the content of the element.
Syntax:
selection.html([value]);
Parameters: This function accepts single parameter as mentioned above and described below:
- Value: It is of type string that sets the HTML to the document.
Return Value: This function does not return anything.
Example 1: In the following code, the HTML “p” element content is changed to “bold” text.
HTML
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" path1tent=
"width=device-width, initial-scale=1.0">
</script>
<style>
p {
background-color: #f2f2f2;
