Go to Exercise page


HTML Code:

<!DOCTYPE html><!-- Declares the document type and version of HTML -->
<html><!-- Begins the HTML document -->
<head><!-- Contains metadata about the document -->
<meta charset="utf-8"><!-- Specifies the character encoding of the document -->
<title>How to define an ordered list</title><!-- Sets the title of the document -->
</head><!-- Ends the head section -->
<body><!-- Contains the content of the document -->
<ol><!-- Starts an ordered list -->
<li>Monitor</li><!-- Defines the first list item -->
<li>Keyboard</li><!-- Defines the second list item -->
<li>Mouse</li><!-- Defines the third list item -->
</ol><!-- Ends the first ordered list -->
<ol start="10"><!-- Starts a new ordered list with a start attribute set to 10 -->
<li>Monitor</li><!-- Defines the first list item with a custom starting number -->
<li>Keyboard</li><!-- Defines the second list item -->
<li>Mouse</li><!-- Defines the third list item -->
</ol><!-- Ends the second ordered list -->
</body><!-- Ends the body section -->
</html><!-- Ends the HTML document -->


  • The HTML document starts with a declaration of its type and version (<!DOCTYPE html>).
  • The <html> element encloses the entire HTML document.
  • The <head> section contains metadata about the document, such as character encoding and title.
  • The <meta charset="utf-8"> tag specifies the character encoding of the document as UTF-8.
  • The <title> tag sets the title of the document.
  • Inside the <body> section, there are two ordered lists (<ol>).
  • The first ordered list contains three list items (<li>), representing items without a custom starting number.
  • The second ordered list also contains three list items, but it starts with the number 10, specified by the start="10" attribute.
  • The HTML document is properly closed with the </html> tag.
