Add Visual Indication for Active Search Bar and Typing

[ojasvi004]

When the search bar is clicked, there should be a visual indication to show that it is in use. This could be a change in color, border or any other visual cue.
Additionally, there should be a similar indication while typing to enhance the user experience.
