                toggleActions: "restart pause reverse pause"
            },
            y: 1000, // Move the box vertically down by 500px
        });
    </script>

</body>

</html>

Explanation:

Structure:

HTML:
- Creates a basic structure with a head and a body.
- Includes a blue square (.box) as the animated element.
- Sets a minimum height for the body to ensure enough scrolling space.
CSS:
- Styles the .box with dimensions, color, margins, and positioning.

GSAP and ScrollTrigger:

Script Imports:
- Loads the GSAP (GreenSock Animation Platform) library for animations.
- Loads the ScrollTrigger plugin for scroll-based animations.
Animation Setup:
- gsap.registerPlugin(ScrollTrigger);: Registers the ScrollTrigger plugin.
- gsap.to(".box", ...): Defines a GSAP animation for the .box element.

ScrollTrigger Configuration:

scrollTrigger: { ... }: Customizes how the animation interacts with scrolling:
- trigger: ".box": Uses the .box element itself as the trigger.
- start: "bottom top": Starts the animation when the top of the box hits the top of the viewport.
- end: "top bottom": Ends the animation when the bottom of the box hits the bottom of the viewport.
- scrub: true: Enables a smooth scrolling effect, syncing the animation with scroll position.
- toggleActions: "restart pause reverse pause": Animation restarts, pauses, reverses, and pauses again as the user scrolls up and down.

Animation Properties:

y: 1000: Animates the .box element to move 1000 pixels downwards.

Key Points:

The animation is triggered and controlled by scrolling.
The box moves downwards as the user scrolls down.
The animation reverses and moves upwards as the user scrolls back up.
The scrub option creates a seamless, synchronized effect.
The toggleActions setting creates a dynamic loop of animation changes based on scroll direction.

4.1.2. Draggable

Example:

gsap.registerPlugin(Draggable);

Draggable.create(".draggable", {
  type: "x,y",
  edgeResistance: 0.65,
  bounds: "#container",
  throwProps: true
});

Here, elements with the class .draggable can be freely moved within the bounds of #container.

</body>
</html>

Explanation:

HTML Structure:
- A div with the class "element" is created and styled as a blue circle, positioned in the center of the screen.
GSAP Animation:
- gsap.to(".element", ...): Targets the "element" for animation.
- duration: 2: Sets the animation duration to 2 seconds.
- x: 100.5: Animates the element's x position to 100.5 pixels.
- roundProps: "x": Automatically rounds the x property to the nearest whole number during the animation.

Key Points:

The circle will animate smoothly to the right, but its final position will be 101 pixels (rounded from 100.5).
The roundProps property provides a convenient way to round specific properties during animation.
This demonstrates how GSAP can create precise animations with controlled rounding behavior.

</body>
</html>

Explanation:

HTML Structure:
- Creates a basic structure with a head and a body.
- Includes three sections (section1, section2, and section3), each taking up the full viewport height.
CSS:
- Styles the sections with full-height layout, centered content, large font size, and a bottom border.

GSAP and ScrollTo:

Script Imports:
- Loads the GSAP (GreenSock Animation Platform) library for animations.
- Loads the ScrollToPlugin for smooth scrolling functionality.
Scroll Animation:
- window.onload = function() { ... }: Executes the animation code when the window loads.
- gsap.to(window, ...): Uses GSAP to animate the window's scroll position.
  - duration: 2: Sets the animation duration to 2 seconds.
  - scrollTo: { y: "#section2" }: Scrolls to the element with ID "section2".
  - ease: "power2.inOut": Applies a power2 easing for a smooth, accelerating-decelerating scrolling effect.

Key Points:

Upon page load, the code smoothly scrolls the page to Section 2 over 2 seconds.
The ScrollToPlugin enables GSAP to animate scrolling behavior.
The "power2.inOut" easing creates a dynamic and visually appealing scrolling experience.
Each section takes up the full viewport height, creating a full-screen scrolling effect.
The CSS styles ensure visual consistency and clear separation between sections.

4.1.10. AttrPlugin

Example:

gsap.to(".mySVG", {duration: 1, attr: {width: 200, height: 200}});

This code changes the width and height attributes of an SVG element.

Use Case in an HTML Project:

<!DOCTYPE html>
<html>
<head>
    <title>GSAP SVG Attribute Animation</title>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.10.3/gsap.min.js"></script>
    <style>
        .mySVG {
            display: block;
            margin: auto; /* Center the SVG */
            border: 1px solid black; /* Just to see the edges clearly */
        }
    </style>
</head>
<body>

    <svg class="mySVG" width="100" height="100" viewBox="0 0 100 100">
        <circle cx="50" cy="50" r="40" stroke="green" stroke-width="4" fill="yellow" />
    </svg>

    <script>
        gsap.to(".mySVG", {
            duration: 1,
            attr: { width: 200, height: 200 }
        });
    </script>

</body>
</html>

Explanation:

HTML Structure:
- Creates a basic HTML structure with a head, body, and an SVG element.
- The SVG has a class of "mySVG", initial width and height of 100 units, and a viewBox to define the drawable area.
- It contains a circle with a green stroke, yellow fill, and a radius of 40 units.
CSS:
- Styles the "mySVG" class to:
  - Display as a block-level element.
  - Center the SVG within its parent container.
  - Add a visible border (for clarity).

GSAP Animation:

Script Import:
- Loads the GSAP (GreenSock Animation Platform) library for animations.
SVG Attribute Animation:
- gsap.to(".mySVG", ...): Targets the "mySVG" element for animation.
  - duration: 1: Sets the animation duration to 1 second.
  - attr: { width: 200, height: 200 }: Animates the SVG's width and height attributes to 200 units.

Key Points:

The code displays a centered SVG with a yellow circle and a green border.
Upon loading, GSAP animates the SVG's width and height to double their size over 1 second.
The circle inside the SVG will grow smoothly as the SVG's dimensions increase.
This demonstrates how GSAP can directly animate SVG attributes for dynamic effects.

4.1.11. ModifiersPlugin

This library provides a wide range of capabilities for modifying tween values during animation, which opens up possibilities for creating unique and customized effects.

Example:

gsap.to(".element", {duration: 2, x: 500, modifiers: {x: gsap.utils.unitize(x => Math.round(x))}});

This code moves an element to the right, rounding the x position to the nearest pixel.

Use Case in an HTML Project:

<!DOCTYPE html>
<html>
<head>
  <title>GSAP Snapping Animation</title>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.10.3/gsap.min.js"></script>
  <style>
    .element {
      width: 50px;
      height: 50px;
      background-color: blue;
      border-radius: 50%;
      position: absolute;
      top: 50%;
      left: 50%;
      transform: translate(-50%, -50%); /* Center the element */
    }
  </style>
</head>
<body>

  <div class="element"></div>

  <script>
    gsap.to(".element", {
      duration: 2,
      x: 500,
      modifiers: {
        x: gsap.utils.unitize(x => Math.round(x))
      }
    });
  </script>

</body>
</html>

Explanation:

HTML Structure:
- A div with the class "element" is created and styled as a blue circle, positioned in the center of the screen.
GSAP Animation:
- gsap.to(".element", ...): Targets the "element" for animation.
- duration: 2: Sets the animation duration to 2 seconds.
- x: 500: Animates the element's x position to 500 pixels.
- modifiers: { ... }: Applies a modifier to the x property for snapping:
  - x: gsap.utils.unitize(x => Math.round(x)): Rounds the x value to the nearest whole number during each frame of the animation, creating a snapping effect.

Key Points:

The circle will animate smoothly to the right, but its position will only update in whole-pixel increments, creating a distinct snapping motion.
This demonstrates how GSAP's modifiers can customize animation behavior for unique effects.
The gsap.utils.unitize function ensures proper unit handling for compatibility across browsers and scenarios.

4.1.12. RoundPropsPlugin

Example:

gsap.to(".element", {duration: 2, x: 100.5, roundProps: "x"});

This code animates an element to the right and rounds the x position.

      width: 50px;
      height: 50px;
      background-color: blue;
      border-radius: 50%;
      position: absolute;
      top: 50%;
      left: 50%;
      transform: translate(-50%, -50%); /* Center the element */
    }
  </style>
</head>
<body>

  <div class="element"></div>

  <script>
    gsap.to(".element", {
      duration: 2,
      x: 100.5,
      roundProps: "x"
    });
  </script>

</body>
</html>

Explanation:

HTML Structure:
- A div with the class "element" is created and styled as a blue circle, positioned in the center of the screen.
GSAP Animation:
- gsap.to(".element", ...): Targets the "element" for animation.
- duration: 2: Sets the animation duration to 2 seconds.
- x: 100.5: Animates the element's x position to 100.5 pixels.
