Where to edit the search form?

I wish to change the search text to icon in my search form. But I couldn’t identify the file where the search form exists. Can you tell the file I have to search in for the search form?

Hello @skishore1992,

Your issue looks like general WordPress issue.

I kindly suggest you to use WordPress.org forums to find a solution, that forums is the right place for general WordPress questions.

Kind Regards, Roman.
