Angular Interview Practice

What is an example of a property that has no corresponding attribute?

1. The value property of an input element

2. The style property of an element

3. The src property of an img element

4. The className property of an element

The correct answer is: The style property of an element

The style property of an element serves as an example of a property that does not have a directly corresponding attribute in the HTML markup. This is because the style property is used to manipulate the inline styles of an element through JavaScript or in an Angular application, while the attribute itself in the HTML may not clearly reflect every possible CSS style that can be applied. For instance, the style property can apply a wide range of CSS styles, combining multiple properties such as color, font-size, margin, padding, and more, all of which are not typically displayed in the HTML attributes as a single attribute. While you'd see a style attribute in the HTML for inline CSS, that would only account for the specific styles written, lacking the flexibility and extensive nature of the style property. On the other hand, other properties like the value property of an input element, the src property of an img element, and the className property of an element have corresponding attributes in the HTML. The value attribute is used for input fields to set or retrieve the value, the src attribute defines the URL of the image, and the className property is directly linked to the class attribute of the elements, representing CSS classes to be applied. These properties and their values are directly reflected in the
