Responsive Navigation Bar
This code is used to design a responsive navigation bar where it dynamically changes according to the screen size. If the screen width is greater than 700px, the “nav-bar” class will be displayed and “small-navbar” will be hidden and vice versa. The style “display” is used with the value “none” to hide the visibility and the value “block” to make it visible. To identify the screen size, the media screen attribute has been used by specifying a min-width. The input element has been used with its type checkbox to display the clickable div; its clicked events have been handled by applying the styles when checked and remove the styles when unchecked.
