CSS transitions are a technology that allows you to create smooth changes in element properties without using JavaScript or third-party libraries. Thanks to them, you can add the effect of a smooth change in color, size, transparency, position, and other parameters.

The main parameters of CSS Transition

  • Property to be changed

Determines which styles the transition will be applied to. It can be a color, size, position, etc.

  • Animation duration

The time it takes for the property to change (for example, 0.5 seconds).

  • Acceleration function

Controls how the speed of the effect changes (steady, slowing down at the beginning or end, etc.).

  • Delay before start

The amount of time the animation waits before it starts.

Popular effects using transition

  • Change the color of buttons on hover

Used to improve the visual perception of interface elements.

  • Smoothly zoom in and out of elements

For example, zoom in on an image or text when you hover the cursor.

  • Change the transparency (fade-in/fade-out effect)

Useful for creating a soft display of elements.

  • Animate menus or blocks

Use to smoothly open and close pop-up elements.

  • Combining with transform

Often, transition is combined with transform to add scaling, rotation, or displacement effects to elements. This makes the user experience more dynamic and engaging.

Conclusion.

CSS transitions are a simple but effective tool for creating modern and interactive web design. They not only improve visual perception but also make the interface more user-friendly.
