@piyushkumar0707 It is good But your UI is crooked.The searchbar looks hoorible and icons are merging into searchbar, looks lik ecode is breaking. Fix that. Also for reference Please make your search bar interactive like this:

• https://codepen.io/shoby/pen/gOrgVVq

This is only a Reference. I DO NOT want Exactly Same Search bar. I want it this way:

• First The search bar will be visible with a search icon, and a text field to type with a placeholder. it will have a small width and it will be compact
• On HOVER or On FOCUS: The search bar will expand noticeably to Double it's size exposing more text field area.
