CSS3 3D Transforms

Welcome to the world of CSS3 3D transforms—a feature that adds depth to web design with rotations, scaling, and translations. Explore the creative possibilities of CSS3 3D for visually captivating and interactive elements.

You can manipulate elements in a three-dimensional space using CSS3's 3D transform feature. This allows you to perform basic transformations such as moving, rotating, scaling, and skewing.

Transformed elements do not affect the surrounding elements, but they can overlap them, similar to absolutely positioned elements. However, even after transformation, the element still occupies space in its default (un-transformed) location within the layout.

The CSS3 transform property utilizes transform functions to manipulate the coordinate system of an element, enabling the application of transformation effects.

The following section explains the 3D transform functions:

It moves the element along the X, Y, and Z axes. It can be expressed as translate(tx, ty, tz). The third translation-value parameter (tz) does not accept percentage values.

<style>
.container{
	width: 125px;
    height: 125px;
    perspective: 500px;
  	border: 4px solid purple;
    background: #fff2dd;
	margin: 30px;
}
.transformed {
    -webkit-transform: translate3d(25px, 25px, 50px); /* Chrome, Safari, Opera */
    transform: translate3d(25px, 25px, 50px); /* Standard syntax */
}
</style>

• Try this code

For example, the function translate3d(25px, 25px, 50px) moves the image 25 pixels along the positive X and Y axes, and 50 pixels along the positive Z-axis.

The perspective and perspective-origin CSS properties control this effect. It adds a sense of depth to a scene by adjusting the element's position on the Z-axis. Elements closer to the viewer appear larger, while those further away appear smaller.

Note: Applying 3D transformations without setting the perspective will not create a convincing three-dimensional effect.

It rotates the element in 3D space around a specified angle and direction vector [x, y, z]. It can be written as rotate(vx, vy, vz, angle).

<style>
.container{
    margin: 50px;
	width: 125px;
    height: 125px;
  	perspective: 300px;
  	border: 4px solid #a2b058;
    background: #f0f5d8;
}
.transformed {
    -webkit-transform: rotate3d(0, 1, 0, 60deg); /* Chrome, Safari, Opera */
    transform: rotate3d(0, 1, 0, 60deg); /* Standard syntax */
}
</style>

• Try this code

For example, the function rotate3d(0, 1, 0, 60deg) rotates the image by 60 degrees along the Y-axis. Negative values can be used to rotate the element in the opposite direction.

It changes the size of an element in three dimensions using the scale3d() function (sx, sy, sz). The effect of scaling may not be apparent unless combined with other transform functions like rotation and perspective.

<style>
.container{
    margin: 50px;
	width: 125px;
    height: 125px;
  	perspective: 300px;
  	border: 4px solid #6486ab;
    background: #e9eef3;
}
.transformed {
    -webkit-transform: scale3d(1, 1, 2) rotate3d(1, 0, 0, 60deg); /* Chrome, Safari, Opera */
    transform: scale3d(1, 1, 2) rotate3d(1, 0, 0, 60deg); /* Standard syntax */
}
</style>

• Try this code

For instance, scale3d(1, 1, 2) scales the element along the Z-axis, and rotate3d(1, 0, 0, 60deg) rotates the image by 60 degrees along the X-axis.

The matrix3d() function enables performing all 3D transformations (translation, rotation, scaling) at once using a 4×4 transformation matrix with 16 parameters.

While the matrix3d() function provides a comprehensive solution for multiple transformations, it is generally more convenient to use individual transformation functions listed in the desired order.

<style>
.container{
    margin: 50px;
	width: 125px;
    height: 125px;
  	perspective: 300px;
  	border: 4px solid #d14e46;
    background: #fddddb;
}
.transformed {
    -webkit-transform: matrix3d(0.359127, -0.469472, 0.806613, 0, 0.190951, 0.882948, 0.428884, 0, -0.913545, 0, 0.406737, 0, 0, 0, 0, 1); /* Chrome, Safari, Opera */
    transform: matrix3d(0.359127, -0.469472, 0.806613, 0, 0.190951, 0.882948, 0.428884, 0, -0.913545, 0, 0.406737, 0, 0, 0, 0, 1); /* Standard syntax */
}
</style>

When applying many transformations at once, however, it is more practical to utilise the individual transformation function and list them in order, as seen below:

<style>
.container{
    margin: 50px;
	width: 125px;
    height: 125px;
  	perspective: 300px;
  	border: 4px solid #d14e46;
    background: #fddddb;
}
.transformed {
    -webkit-transform: translate3d(0, 0, 60px) rotate3d(0, 1, 0, -60deg) scale3d(1, 1, 2); /* Chrome, Safari, Opera */
    transform: translate3d(0, 0, 60px) rotate3d(0, 1, 0, -60deg) scale3d(1, 1, 2); /* Standard syntax */
}
</style>

The list below provides a concise summary of all the 3D transformation functions:

• translate3d(tx,ty,tz): Moves the element along the X, Y, and Z axes.
• translateX(tx): Moves the element along the X-axis.
• translateY(ty): Moves the element along the Y-axis.
• translateZ(tz): Moves the element along the Z-axis.
• rotate3d(x,y,z, a): Rotates the element in 3D space around the specified direction vector [x, y, z] by the given angle.
• rotateX(a): Rotates the element by the given angle around the X-axis.
• rotateY(a): Rotates the element by the given angle around the Y-axis.
• rotateZ(a): Rotates the element by the given angle around the Z-axis.
• scale3d(sx,sy,sz): Scales the element along the X, Y, and Z axes. Note that scale3d(1,1,1) has no effect.
• scaleX(sx): Scales the element along the X-axis.
• scaleY(sy): Scales the element along the Y-axis.
• scaleZ(sz): Scales the element along the Z-axis.
• matrix3d(n,n,n,n,n,n, n,n,n,n,n,n,n,n,n,n): Specifies a 3D transformation using a 4×4 transformation matrix with 16 values.
• perspective(length): Defines a perspective view for a 3D transformed element. Increasing the value of this function generally makes the element appear further away from the viewer.

What are CSS3 3D Transforms?

CSS3 3D Transforms are a set of CSS properties and functions that allow you to manipulate and transform elements in three-dimensional space. They enable you to apply various transformations like rotation, scaling, translation, and skewing in the X, Y, and Z dimensions to create three-dimensional effects in web design.

Which CSS properties are commonly used for 3D transformations?

The commonly used CSS properties for 3D transformations are:

• transform: This property is the foundation for applying various transformations, including 3D transformations.
• transform-origin: It defines the point around which transformations occur.
• rotateX, rotateY, rotateZ: These properties allow you to rotate an element around its X, Y, or Z axis, respectively.
• scaleX, scaleY, scaleZ: These properties control the scaling of an element in the X, Y, or Z dimension.
• translateX, translateY, translateZ: These properties move an element along the X, Y, or Z axis.

How can you create a 3D-transformed element?

To create a 3D-transformed element, you can use the transform property with one or more transformation functions. For example, to rotate an element around the X-axis by 45 degrees, you can use the following CSS:

transform: rotateX(45deg);

What is the difference between perspective and perspective-origin properties in 3D transformations?

• perspective: This property determines the depth of the perspective in a 3D transformed element. It defines how far away the viewer appears to be from the object. Larger values create a stronger perspective effect.
• perspective-origin: It defines the point within the element from which the viewer is looking at the 3D space. You can use it to change the viewpoint for the perspective, which can significantly affect how the 3D transformations are perceived.

What is the purpose of the backface-visibility property in 3D transformations?

The backface-visibility property determines whether or not the back face of an element is visible when it is rotated or transformed in 3D space. It can take two values:

• visible: The back face is visible, and any content on it will be displayed.
• hidden: The back face is not visible and is effectively hidden from view. This is useful for optimizing performance when you don't need to display the back face of an element.

How can you combine multiple 3D transformations on an element?

You can combine multiple 3D transformations on an element by chaining transformation functions within the transform property. For example, to rotate an element around the X and Y axes simultaneously, you can use:

transform: rotateX(45deg) rotateY(30deg);

This will apply both rotations to the element.

What is the difference between a 2D transformation and a 3D transformation in CSS?

A 2D transformation in CSS operates in a two-dimensional plane, allowing you to manipulate elements along the X and Y axes. In contrast, a 3D transformation adds the Z-axis, enabling you to create three-dimensional effects by manipulating elements in three dimensions, including rotation, scaling, and translation along the X, Y, and Z axes.

What is the purpose of the transform-style property in 3D transformations?

The transform-style property is used to define how child elements within a 3D transformed container are treated in terms of 3D transformations. It can have two values:

• flat: This value is the default and treats child elements as if they are flattened onto the plane of the parent, essentially ignoring 3D transformations of child elements.
• preserve-3d: This value maintains the 3D positioning and transformations of child elements within a 3D transformed parent. It's essential for creating complex 3D scenes.

Can you combine 2D and 3D transformations on the same element?

Yes, you can combine 2D and 3D transformations on the same element by using both 2D and 3D transformation functions within the transform property. For instance, you can rotate an element in 2D and then translate it along the Z-axis in 3D space. Here's an example:

transform: rotate(45deg) translateZ(50px);

This rotates the element 45 degrees in the XY plane and moves it 50 pixels along the Z-axis.

The power of CSS3 3D transforms opens up a realm of possibilities for creating immersive and visually striking web experiences. The 3D transform property, with its animatable nature, allows developers to bring elements to life through rotations, scaling, translations, animations, and transitions in three-dimensional space. Incorporating CSS perspective further enhances the depth and realism of 3D transformations, providing a captivating visual impact.

Whether it's rotating images, scaling elements, or translating objects, the versatility of 3D transformations empowers developers to elevate their design aesthetics, resulting in engaging and interactive web content.
