Utilizing technologies like CSS in JS allows for the creation of dynamic CSS properties, a significant advantage when working with frameworks such as Material UI.
Imagine implementing a fade-in effect for displaying cards, with each card appearing at equal intervals:
- All cards will take 1 second to reveal themselves, maintaining consistency from start to finish.
- Each card will have the same duration for fading in.
- Following the completion of one card's animation, the next card will begin its fade-in process with an appropriate delay based on the previous card's duration.
If dealing with just two cards, setting the CSS animation-duration to 0.5 seconds and an animation-delay of 0.5 seconds for the second card would be sufficient.
However, if the number of cards is unknown or subject to change (dynamic data), traditional static CSS properties are insufficient. It is only through combining JavaScript with CSS that we can access and manipulate dynamic variables, thereby incorporating them into our style sheets.
CSS in JS serves as a powerful tool for achieving this capability, with options like Styled Components and Emotion offering robust solutions. Beyond enabling dynamic styling, CSS in JS also promotes reusability by treating styles as objects before translating them to CSS rules. This versatile approach proves invaluable in creating interactive and engaging user interfaces.
