🔍 CSS 3D Keywords Explained

transform: This is the property that lets you move, rotate, scale, or skew an element. In 3D, it helps position elements along the X, Y, and Z axes. For example, transform: rotateY(180deg) flips an element horizontally.

rotateX, rotateY, rotateZ: These are specific values for the transform property. They rotate the element around the respective axis:

rotateX: Rotates the element like a lid opening or closing.
rotateY: Rotates the element left or right like flipping a book.
rotateZ: Spins the element clockwise or anticlockwise like turning a dial.

scale: Changes the size of the element. For 3D effects, you might see scale(1.2) (enlarges) or scale(0.8) (shrinks).

translateZ: Moves the element closer or farther away from the viewer. Positive values bring it closer, negative values push it back. It's crucial for creating depth.

perspective: This defines how far the viewer is from the element. It gives a sense of depth. Think of it like a camera lens. A smaller value (like perspective: 200px) creates a more dramatic 3D effect; a larger one (like 1200px) appears flatter.

transform-style: preserve-3d: This tells the browser to maintain the 3D space for the children of the element. Without it, child elements will be flattened into 2D even if they have 3D transforms applied.

backface-visibility: This controls whether the backside of an element is visible when rotated. In flip cards, you usually set this to hidden so the back doesn't show through the front.

animation: Used to animate CSS properties over time. In the cube example, we use @keyframes with rotateX and rotateY to spin the cube smoothly.

@keyframes: This rule defines the animation steps. For example:

@keyframes rotateCube {
  0%   { transform: rotateX(0deg) rotateY(0deg); }
  100% { transform: rotateX(360deg) rotateY(360deg); }
}

transition: This creates smooth motion when a property like transform changes. Example: transition: transform 0.6s; makes a rotation happen over 0.6 seconds rather than instantly.

hover: Not a keyword, but an essential selector. It activates styles when you place your mouse over an element. Many 3D effects respond to :hover.

These keywords work together to build realistic, interactive 3D experiences using just CSS—no JavaScript or heavy libraries required!

🧪 Example 1: 3D Flip Card

This effect uses transform-style: preserve-3d and flips the card on Y-axis when hovered.

Front

Back

<div class="flip-card">
  <div class="flip-card-inner">
    <div class="flip-card-front">Front</div>
    <div class="flip-card-back">Back</div>
  </div>
</div>

<style>
  .flip-card {
    width: 200px; height: 250px;
    perspective: 1000px;
  }
  .flip-card-inner {
    width: 100%; height: 100%;
    transform-style: preserve-3d;
    transition: transform 0.6s;
    position: relative;
  }
  .flip-card:hover .flip-card-inner {
    transform: rotateY(180deg);
  }
  .flip-card-front, .flip-card-back {
    backface-visibility: hidden;
    position: absolute;
    width: 100%; height: 100%;
    display: flex; justify-content: center; align-items: center;
  }
  .flip-card-front { background: lightgreen; }
  .flip-card-back {
    background: teal; color: white;
    transform: rotateY(180deg);
  }
</style>

🧪 Example 2: 3D Tilt on Hover

When you hover, this box tilts using rotateX and rotateY for a depth illusion.

Hover Me!

<div class="tilt-card">Hover Me!</div>

<style>
  .tilt-card {
    width: 300px; height: 200px;
    background: #0077cc; color: white;
    font-size: 24px; text-align: center;
    line-height: 200px;
    transition: transform 0.2s;
    perspective: 1000px;
  }
  .tilt-card:hover {
    transform: rotateX(10deg) rotateY(15deg);
  }
</style>

🧪 Example 3: Zoom-In 3D Entry

Uses a combination of scale() and translateZ() for dramatic 3D zooming effect.

Welcome to 3D World!

<div class="zoom-in">Welcome to 3D World!</div>

<style>
  .zoom-in {
    font-size: 2rem;
    padding: 20px;
    background: linear-gradient(to right, #0099f7, #f11712);
    color: white;
    transform: translateZ(-300px) scale(0.2);
    animation: zoomIn 2s forwards;
    transform-style: preserve-3d;
    perspective: 1000px;
  }
  @keyframes zoomIn {
    to {
      transform: translateZ(0px) scale(1);
    }
  }
</style>

🧪 Example 4: 3D Cube Rotation

A rotating cube using preserve-3d, rotateX, and rotateY. Each face is styled separately.

Front

Back

Right

Left

Top

Bottom

<div class="zoom-in">Welcome to 3D World!</div>

<style>
  .zoom-in {
    font-size: 2rem;
    padding: 20px;
    background: linear-gradient(to right, #0099f7, #f11712);
    color: white;
    transform: translateZ(-300px) scale(0.2);
    animation: zoomIn 2s forwards;
    transform-style: preserve-3d;
    perspective: 1000px;
  }
  @keyframes zoomIn {
    to {
      transform: translateZ(0px) scale(1);
    }
  }
</style>
