How to use conditional classes in Vue
Thursday, October 9, 2025
Conditional classes in Vue enable dynamic styling that responds to component state, creating interactive interfaces where styling changes based on data and events. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented conditional classes in thousands of Vue components for dynamic theming and state-based styling. From my expertise, the most effective approach is using object syntax for simple conditions and computed properties for complex logic. This method provides reactive styling that automatically updates when component state changes.
