Needs to make the components size upto the browser window

[navintc]

Currently there's only 3 main components (sections) in the page render and it takes only a half of the browser window to render them. It is required to make these components take up the whole browser window.

• Recommended to size up the mid component (currently: Home component) by a style={{ height: "100%"}} or something more suitable.
• External Global CSS recommended. -- Create a new css file named, global.css file inside the pages folder and use it.
• Page should not be longer than the initial browser size. (optional)
