     + result + "</p>");
  1. First, we write <! DOCTYPE html> which we used as an instruction to the web browser about what version of HTML file is written in.
  2. Secondly, the <html> tag is used to indicate the beginning of an HTML document.
  3. As above now <head> tag is used to contain information about web page. In this tag a <title> tag is used which helps us to specify a webpage title. Both <head> and <title> tags are Paired tags. So, both have </head> and </title> ending tags respectively.
  4. Here, then we create a body tag. All the content which we want to show on browser’s screen or display is always written inside this codes.
  5. As you can see under body we create some checkboxes, its total five. And name used here is car. As we know the name must be same for all checkbox for specific condition.
  6. After that we create a button, on click on that our function runs which is created in script tag.
  7. Now, let us understand script which is created after button.
  8. Script is a paired tag and we use it here to write JavaScript. Under script, we create a variable checkboxes which get values from all checkboxes. The values like they are clicked or not.
  9. In next step we again create a variable named result to show result. After that we use for loop to check how many checkboxes are checked.
  10. And if checkboxes are checked then value directly send to result variable which print result at last. We hope you understand codes properly.
  11. At last, the <body> and <html> tags are closed with </body> and </html> respectively.
