translate3d

translate3d is a CSS function that allows for the translation of an element in three-dimensional space. It takes three arguments: a translation along the x-axis, a translation along the y-axis, and a translation along the z-axis. These values can be specified in any valid CSS length unit, such as pixels, ems, or percentages.

The primary benefit of using translate3d is its ability to leverage the graphics processing unit (GPU) for rendering. When translate3d is used, the browser often offloads the translation operation to the GPU, which can result in smoother animations and improved performance, especially for complex transformations or when animating multiple elements simultaneously. This is because GPUs are optimized for parallel processing, making them highly efficient at handling the calculations required for 3D transformations.

In contrast to the 2D translation functions like translateX() and translateY(), translate3d introduces the z-axis, allowing for depth and perspective in web page layouts. This can be used to create effects such as parallax scrolling, animations that move towards or away from the viewer, and more sophisticated visual compositions.

When an element is translated using translate3d, it is taken out of the normal document flow. This means that other elements on the page will not reflow to accommodate the translated element's new position. The translate3d function is often used within the CSS transform property, which can be applied to various HTML elements to alter their appearance and positioning.
