Differences between normal CSS and Responsive CSS :

• CSS  refers to Section in which we apply Style procedure, and Style refers to color, Margin, font for table paragraphs, and Heading, etc.  It allows one to adapt the presentation to different types of devices, such as large screens, small screens, or printers.

• Responsive CSS responds to the size of the browser at any given point. No matter what the browser width may be, the site adjusts its layout in a way that is optimized to the screen.
