What is ngStyle directive in Angular?

The ngStyle directive in Angular is used to dynamically set CSS styles for an HTML element. It allows you to apply styles based on specific conditions or variables.

With ngStyle, you can use inline styles to apply CSS properties to an element. This is useful for applying dynamic styles based on user interactions, data changes, or other conditions within your Angular application.

Here’s an example of how you can use the ngStyle directive in Angular:

      
        <div [ngStyle]="{ 'color': textColor, 'font-size': fontSize + 'px' }">
          This text will have dynamic styles
        </div>
      
    

In this example, the ngStyle directive is bound to an object where the keys are CSS property names and the values are variables from the component class. This allows the styles of the div element to change dynamically based on the values of textColor and fontSize.

Overall, the ngStyle directive provides a convenient way to apply dynamic styles to your Angular application without having to write complex CSS logic within your component classes.
