ngClass<\/a><\/strong>, as defined by the Angular documentation, is a built-in attribute directive that dynamically modifies the behavior of other HTML elements. <\/p>\n\n\n\n

Common use cases<\/h2>\n\n\n\n

Conditional Styling<\/strong><\/h3>\n\n\n\n

Let’s consider a button element that changes color based on whether it’s disabled or active. We can use ngClass<\/code><\/strong> to toggle between the ‘active-btn’ and ‘disabled-btn’ classes, giving the button a responsive touch:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

Whenever the button is clicked, the toggleDisabled()<\/code> function will be executed, toggling the value of isDisabled<\/code>.<\/p>\n\n\n\n

As a result, the button will become enabled or disabled based on the updated value of isDisabled<\/code>, and the corresponding style (active or disabled) will be applied.<\/p>\n\n\n\n

Using an Object<\/strong><\/h3>\n\n\n\n

ngClass<\/code> goes beyond just toggling classes. It also lets you iterate over object properties to apply your styles conditionally. This can be handy when working with data-driven apps or displaying dynamic content.<\/p>\n\n\n\n

For example, using the following data:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

In our HTML, we can apply dynamic styles using an array:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

Based on the type (‘hero’ or ‘villain’), the directive applies the appropriate highlight class to the hero card.<\/p>\n\n\n\n

Combining classes using conditions<\/strong><\/h3>\n\n\n\n

With ngClass<\/code><\/strong>, you can mix multiple CSS classes, toggling them individually or creating compound styles:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The hero cards will be highlighted for heroes who can fly and have a different style for heroes who cannot, based on the canFly<\/code><\/strong> property.<\/p>\n\n\n\n
