Vue Js Dynamic Class Binding: Vue.js allows dynamic class binding using the v-bind directive. Dynamic class binding allows us to apply or remove a class based on a certain condition or expression. We can bind a class to an HTML element using the v-bind:class directive. We can also use shorthand syntax like :class to achieve the same effect. We can bind multiple classes and also use inline expressions to calculate the class value dynamically. This feature allows us to apply conditional styles to elements, toggle classes based on user interaction, and create responsive designs. Dynamic class binding is a powerful feature in Vue.js that allows us to create dynamic and engaging user interfaces.

How do you use dynamic class binding in Vue.js to conditionally add or remove CSS classes based on Condition?

In Vue.js, dynamic class binding can be used to add or remove CSS classes based on a condition.

To conditionally add or remove a CSS class based on a condition, you can use the v-bind directive with the :class attribute, and provide an object with the CSS class name as the key, and the condition as the value.

Here’s an example code snippet that demonstrates this:

Vue js Dynamic class Binding Example

<div id="app">
   <div :class="{ 'class-name': condition }">This text will be red if the condition is true.</div>
   <button @click="condition = !condition">toggle condition</button>
</div>
<script type="module">
        const app = new Vue({
            el: "#app",
            data() {
                return {
                    condition: false
                }
            },

        });
    </script>
    <style scoped>
        .class-name {
            color: red;
            font-weight: bold;
            background-color: yellow;
            padding: 10px;
            border: 2px solid black;
        }
  </style>
