  • Add a style object with the class MyHeader, which extends React.
  • Instead of background-color: class, use backgroundColor: MyHeader is a React extension.
  • Make a style object with the name mystyle: MyHeader is a React-based class.

colour = "red"; the style change can be applied dynamically. When you supply the element's id to the function, it changes the colour of the element to red. setAttribute(key, value) can also be used to apply a style to an element. You could, for example, call element to change the colour of an element to red.

Components are dynamic in that they can describe an HTML template and fill in variable data as the building blocks of React applications. To demonstrate dynamic components, this class creates a real-world example of a blogging application.

A StyleSheet is comparable to CSS StyleSheets in that it is an abstraction. Instead of establishing a new style object each time, StyleSheet assists in the creation of style objects with an ID, which is then referenced rather than rendered again.
