🙋 Introduction

The transition-timing-function property in CSS defines how intermediate values for CSS properties being affected by a transition are calculated.

This property allows you to control the speed of the transition, making it start slowly, speed up, or slow down at different points during the transition. It is essential for creating smooth and natural animations on your web pages.

💡 Syntax

The syntax for the transition-timing-function property is as follows:

Syntax

Copied

element {
  transition-timing-function: timing-function;
}

Here, timing-function can be one of several predefined keywords, a cubic-bezier function, or the steps function.

🎛️ Default Value

The default value of the transition-timing-function property is ease, which starts the transition slowly, speeds it up in the middle, and slows it down again before completion.

🏠 Property Values

Value	Description
ease	Starts slow, speeds up, then slows down (default).
linear	Constant speed from start to finish.
ease-in	Starts slow, then speeds up.
ease-out	Starts fast, then slows down.
ease-in-out	Starts slow, speeds up, then slows down.
cubic-bezier(n, n, n, n)	Defines a cubic Bezier curve. The values range from 0 to 1.
steps(int,start/end)	Divides the transition into equal steps. The integer specifies the number of steps.

📄 Example

In this example, we'll change the background color of a <div> element with a smooth transition using the ease-in-out timing function.
