The transition-property CSS property is used to specify the properties that should be transitioned when a CSS transition is applied to an element. It allows you to control which properties will have a smooth transition effect when their values change.
The transition-property property accepts one or more values:
- Individual property names: You can specify the name of a specific CSS property that you want to transition. For example,
transition-property: color;transitions thecolorproperty when its value changes. - The
allkeyword: This keyword indicates that all animatable properties should be transitioned. For example,transition-property: all;transitions all properties that have an animatable value.
Here’s an example:
.button {
transition-property: width, background-color;
}
In this example, the .button class sets the transition-property property to width, background-color, indicating that the width and background-color properties will have a transition effect when their values change.
It’s important to note that not all CSS properties are animatable by default. Only properties that have a discrete set of values, such as colors, lengths, or percentages, can be transitioned. Other properties, like display or visibility, cannot be transitioned.
The transition-property property is commonly used in combination with other transition-related properties, such as transition-duration, transition-delay, and transition-timing-function. Together, these properties allow for the creation of smooth and controlled transitions between different states of an element.
By specifying different transition properties, you can choose which aspects of an element’s appearance should have a smooth transition effect. This gives you precise control over which properties change smoothly and which properties change instantly.
Remember to consider the desired visual effect, the specific properties you want to transition, and the overall user experience when using the transition-property property. Be mindful of the properties you choose to transition, as excessive or unnecessary transitions can lead to visual clutter or unnecessary complexity.
