Once your development server is running, you are ready to start toggling classes.

Creating a Toggle Component

Let's create a simple Vue component that includes a button and a div. The div will have a class that can be toggled upon clicking the button.

In the above template, we use Vue's v-bind:class directive (or its shorthand :class) to dynamically bind a class. isActive is a boolean data property that determines whether the class active is applied.

Script Section

Now, let's define the script for this component to handle the toggleClass method and the isActive property.

In this script, we initialize isActive to false. The toggleClass method switches the value of isActive between true and false each time the button is clicked.

Styling the Component

Finally, let's add some CSS to visualize the toggling effect.

Here, the active class changes the background color of the div to blue. The transition property ensures a smooth change.

Combining all the parts, your component file would look like this:
