Perspective

The transform property, matters.If perspective() comes after the translateZ() function, it would have NO effect.Let's try doing this for real:CSSdiv { width: 100px; height: 100px; background-color: blue; transform: translateZ(-500px) perspective(1000px); /* Order reversed */}See? The square remains as it is even though the transform property does exist on it.That's because perspective() comes after the translateZ() function.The perspective propertyThe perspective property is the same as the perspective() function in what it does. However, there sure is some difference between both these utilities.The perspective() function, as we saw above, applies perspective to a given element, the one on which it's applied. In contrast,The perspective property applies perspective to all the children of a given element, excluding the element itself.Technically speaking, perspective is more powerful than the perspective() function. How?Because it creates a single 3D space that is shared by all the children of an element.Moreover, as we shall learn later on below, perspective can be used alongside the perspective-origin property to further improvise the positioning of the view point of a projection on the xy plane.More or less, perspective could be thought of as manually going over each and every child of the element on which it's applied and then calling the perspective() function on it.Once again, remember that perspective does NOT apply perspective to the element on which it is set.Here's the syntax of the perspective property, which is, needless to say, akin to the perspective() function:perspective: On older browsers, perspective is behind vendor prefixing.On Webkit-based browsers, it's called, as you can guess, -webkit-perspective. On Firefox, it's called -mox-perspective. There's even a non-standard property for IE; it's called -ms-perspective.Painful compatibility issues.The other important points worth noting about the perspective property are as follows:perspective creates a new stacking context.perspective makes the underlying element a containing block for descendant elements, for e.g. ones

Quick links to procedures on this page: Adding perspective to objects creates the illusion of distance and depth. You can create a perspective effect by shortening one or two sides of an object. This effect gives an object the appearance of receding in one or two directions, thereby creating a one-point perspective or a two-point perspective. The original graphic (left) with one-point (middle) and two-point (right) perspective applied to it. CorelDRAW lets you use perspective with both vector and bitmap objects. You add perspective to a bitmap interactively in the drawing window. Two-point perspective (bottom left) is applied to a bitmap (top left). The perspective effect is applied nondestructively, so you can edit it or remove it and revert to the original image at any point. After you add perspective to bitmaps, you can transform and manipulate them as you would any other vector objects. For information about transforming objects, see Working with objects. Perspective effects can be added to objects or grouped objects. Perspective is applied to a group of vector and bitmap objects You can also add a perspective effect to linked groups, such as contours, blends, and extrusions. You can’t add perspective effects to paragraph text or symbols. You can adjust perspective by moving the nodes on the perspective grid or the vanishing points. Moving a node lets you edit a two-point perspective; moving a vanishing point lets you edit a one-point perspective. After you apply a perspective effect, you can copy it to other objects in a drawing, adjust it, or remove it from the object. Pressing Ctrl constrains the node’s movement to the horizontal or vertical axis to create a one-point perspective effect. Press Ctrl + Shift as you drag to move two adjacent nodes symmetrically towards or away from a central point. This is

Instead, at its own center. To recap it, in comparison, the view point of each element in the previous example is a single, shared point — the center of .In short, if we wish to get a combined 3D transformation effect on a list of sibling elements (with a common parent), then perspective is what we need.Otherwise, if we don't want a combined 3D effect, we have to manually apply perspective() to each sibling element, or possibly go with another different approach.The perspective-origin propertyNow, let's talk about the equally important property, often used along with the perspective property — perspective-origin.The perspective-origin property specifies the location of the perspective view point on the xy plane, which is simply the plane consisting of the x-axis and y-axis.For example, if the perspective-origin of a square object is at its top-left corner, as follows,Square object with perspective-origin situated at the top-lefthere's how the corresponding perspective view point will look from the side:Side view of square object with perspective-origin situated at the top-leftSee how perspective-origin influences the positioning of the view point — it is in-line with the perspective-origin.To be precise, perspective-origin positions the view point in the x and y axes — positioning in the z-axis is already covered by the perspective property, as we saw above.Syntactically, perspective-origin is identical to transform-origin:perspective-origin: x-positiony-position | x-positionIt can either have two values, representing the x and y offsets of the view point, respectively, or just one value, representing only the x offset of the viewpoint.As a matter of fact, in the case of two values, depending on the keywords used, the first value could even represent the y offset while the second one represents the x offset.Let's consider some examples demonstrating perspective-origin.First, let's see a simple case using the default value of perspective-origin.In the following code,
