In this example: - We use HTML to create the structure of the webpage, including a button with the id 'changeColorBtn'. - We use CSS to style the elements on the page. - In the JavaScript section: - - We select the button element using 'getElementById'. - - We add an event listener to the button using 'addEventListener', which listens for a 'click' event and executes a callback function when the button is clicked. - - Inside the callback function, we generate a random color using 'Math.random()' and set it as the background color of the body element using 'document.body.style.backgroundColor'. - - We also log the color change to the console using 'console.log'. This example demonstrates fundamental concepts such as DOM manipulation, event handling, and basic JavaScript syntax.
