CSS transition-timing-function Property

Description

The transition-timing-function property is used to describe how the intermediate values of the CSS properties being affected by a transition effect are calculated. This in essence lets you establish an acceleration curve, so that the speed of the transition can vary over its duration.

Initial value

ease

Applies to

All elements, :before and :after pseudo elements

Inherited

No

Media

Interactive

Computed value

Same as specified value

Animatable

No

CSS Version

CSS3

JavaScript syntax

object.style.transitionTimingFunction

Syntax

transition-timing-function: <single-transition-timing-function> [ ',' <single-transition-timing-function> ]*

Values

• easeThe ease function is equivalent to cubic-bezier(0.25, 0.1, 0.25, 1).
• linearThe linear function is equivalent to cubic-bezier(0, 0, 1, 1).
• ease-inThe ease-in function is equivalent to cubic-bezier(0.42, 0, 1, 1).
• ease-outThe ease-out function is equivalent to cubic-bezier(0, 0, 0.58, 1).
• ease-in-outThe ease-in-out function is equivalent to cubic-bezier(0.42, 0, 0.58, 1)
• step-startThe step-start function is equivalent to steps(1, start).
• step-endThe step-end function is equivalent to steps(1, end).
• steps(<integer>[, [ start | end ] ]?) Specifies a stepping function, described above, taking two parameters. The first parameter specifies the number of intervals in the function. It must be a positive integer (greater than 0). The second parameter, which is optional, is either the value 'start' or 'end', and specifies the point at which the change of values occur within the interval. If the second parameter is omitted, it is given the value 'end'.
• cubic-bezier(<number>, <number>, <number>, <number>)Specifies a cubic-bezier curve. The four values specify points P1 and P2 of the curve as (x1, y1, x2, y2). Both x values must be in the range [0, 1] or the definition is invalid. The y values can exceed this range.
