CSS Properties: How to specify that the background color should be transparent?

Go to Exercise page


HTML Code:

<!DOCTYPE html>
<meta type="utf-8" /><!-- Specify the character encoding of the HTML document -->
<title>How to specify that the background color should be transparent</title><!-- Set the title of the HTML document -->
<style type="text/css">/* CSS style start*/
#test {
background-color: transparent; /* Set the background color of the element with id="test" to transparent */
<p>This is a paragraph.</p><!-- Display a paragraph within a div element -->


  • The CSS rule targets an element with the id "test" (#test).
  • It sets the background-color property of that element to transparent, making the background color of the element transparent.
  • The HTML document includes a paragraph (<p>) element within a <div> element, but this paragraph is not affected by the CSS rule because it doesn't have the id "test".
