React Js Add Multiple Class to Element

React Js Add Multiple Class to Element : In React.js, you can add multiple classes to an element in a few ways. First, you can directly assign multiple classes using the className attribute, like className="class1 class2". To add classes conditionally, use a ternary operator: className={condition ? 'class1' : 'class2'}. For adding multiple classes from a string, you can concatenate or interpolate the class names, like className={'class1 ' + myClassString}. Alternatively, with ES6 template literals, it can be done as className={class1 ${myClassString}`}. These techniques allow you to manage element styling dynamically in your React components

How can you add multiple classes to an element in a Reactjs?

In this React.js code snippet, we define a functional component called App. Within it, we create a variable multipleClassNames containing a string with multiple CSS class names separated by spaces. We then use the className attribute to apply these classes to a div element within a container. This allows you to add multiple CSS classes to the element, resulting in styling from 'class1', 'class2', and 'class3' being applied to the inner div. When this component is rendered using ReactDOM, the element will have the specified CSS classes, enabling custom styling for the React component.
