Toggle CSS Classes on an Element
Discover how to easily add, remove, or toggle CSS classes on any HTML element using JavaScript's `classList` API for dynamic styling and state changes.
const element = document.getElementById('myToggleElement');
// Assuming 'myToggleElement' exists and you want to toggle 'active' class
if (element) {
element.classList.toggle('active');
console.log('Element now has active class:', element.classList.contains('active'));
// You can also explicitly add or remove:
// element.classList.add('highlight');
// element.classList.remove('inactive');
}
How it works: The `classList` property provides a simple way to manipulate an element's CSS classes. `classList.toggle('className')` is particularly useful for switching between two states, adding the class if it's not present, or removing it if it is. This is ideal for interactive UI components like tabs, menus, or active state indicators.
