  1. To begin, we need to write <HTML>, which tells the browser what version of HTML we're using. HTML documents contain tags as their first element.
  2. In the head tag, describe the heading of the project. There are no closed brackets in the title and final brackets, unlike the final brackets.
  3. The <script> tag was then added. The script tag also includes the javascript google API run or an explanation of the code or file we used.
  4. In addition to closing the script, the head is also closed.
  5. In this case, the body tag describes the body of the website. Basically, this is where you write the content for the website.
  6. Clicking the Submit button after selecting the Yes checkbox will result in a message.
  7. You will see an error message if you click the Submit button on a form where the checkboxes are unchecked.
  8. Our next step was to open the script.
  9. In order to declare an alert, we create an if statement and an else statement.
  10. Then we close </script> </body></html>
