How to make a Bookmarklet

1. Write a JavaScript function to perform the desired task. For example:

                 
                   javascript:(function() {
                     alert('Hello World');
                     document.body.style.backgroundColor = 'lightblue';
                   })();
                 
               

2. Copy the code and prepend it with the `javascript:` prefix. Remove any newlines or unnecessary spaces.
