d) Implement a simple "Hello World" HTML page. Using CSS and JavaScript, add a radio button that will allow the user to switch between day mode (i.e., white background, black text) and night mode (i.e., black background, white text). e) Implement HTML and JavaScript code that displays 3 text fields and a button. When a user inputs a number in the first text field and a number in the second text field and then clicks the button, the third text field should display the average of the two numbers.

In this lab, you will use a timer to animate the movement of a heart image to the location where the mouse clicks, as shown below. In jacascript, please! The given web page shows a heart image. When the user clicks anywhere in the page, the startAnimation() function is called. startAnimation() determines where the user clicked and calls moveImage() with the clicked (x, y) coordinate. moveImage() moves the heart 1 pixel in the direction of the given (x, y) coordinates. Make the following JavaScript modifications using clearInterval() and setInterval() where appropriate: In startAnimation(), add an if statement that stops the timer with the ID timerId if timerId is not null. In startAnimation(), start a timer that calls moveImage(clickX, clickY) every 10 milliseconds. Save the timer ID in the timerId variable. Add an if statement in moveImage() that stops the timer with the ID timerId if (imgX, imgY) is equal to (centerX, centerY). Also set timerId to null. After the…

Please rewrite this animation code below so that it performs the same functions in a java file instead of the files .css,.js, and .html in visual studios. You would need to import javaFX and include your images for creature.png,forestbackground.png,human.png, and human2.png. Also attach a screenshot of the running animation in java. script.js const dialogue = [ { character: 'Narrator', text: "In the dead of night, beneath a moon veiled by misty clouds, a lone figure trudged along a desolate forest path." }, { character: 'Narrator', text: "Unknown to her, she was not alone." }, { character: 'Human', text: "Who's there?
