The transition CSS property is shorthand for transition-property, transition-duration, transition-timing-function, and transition-delay.
Syntax
CSS
transition: value;
JS
object.style.transition = "value";
Values
<'transition'> = <single-transition>#
<single-transition> = [ none | <single-transition-property> ] || <time> || <easing-function> || <time>
none
No property will transition.
<single-transition-property> = all | <custom-ident>
all
Indicates all properties are to be transitioned.
<custom-ident>
Specifies any valid identifier that is not misinterpreted as a keyword.
<time>
Defines how long of a delay there is between the start of the animation and when it begins executing.
ms
Milliseconds. There are 1000 milliseconds in 1 second.
s
Seconds.
<easing-function> = linear | <cubic-bezier-easing-function> | <step-easing-function>
linear
Its output progress value is equal to the input progress value for all inputs.
<cubic-bezier-easing-function> = ease | ease-in | ease-out | ease-in-out | cubic-bezier(<number>, <number>, <number>, <number>)
ease
Equivalent to cubic-bezier(0.25, 0.1, 0.25, 1).
ease-in
Equivalent to cubic-bezier(0.42, 0, 1, 1).
ease-out
Equivalent to cubic-bezier(0, 0, 0.58, 1).
ease-in-out
Equivalent to cubic-bezier(0.42, 0, 0.58, 1).
cubic-bezier()
Specifies a cubic Bezier easing function. The four numbers 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.
<number>
An integer or zero or more decimal digits followed by a dot (.) followed by one or more decimal digits. The first character may be preceded by a sign (- or +). The last character may be succeeded by an exponent (e or E) and an integer.
<step-easing-function> = step-start | step-end | steps(<integer>[, <step-position>]?)
step-start
Computes to steps(1, start)
step-end
Computes to steps(1, end)
steps()
The first parameter specifies the number of intervals in the function. It must be a positive integer greater than 0 unless the second parameter is jump-none in which case it must be a positive integer greater than 1. The second parameter, which is optional, specifies the step position.
<integer>
Specifies one or more decimal digits (0-9).
<step-position> = jump-start | jump-end | jump-none | jump-both | start | end
jump-start
The first rise occurs at input progress value of 0.
jump-end
The last rise occurs at input progress value of 1.
jump-none
All rises occur within the range (0, 1).
jump-both
The first rise occurs at input progress value of 0 and the last rise occurs at input progress value of 1.
start
Behaves as jump-start.
end
Behaves as jump-end.
