Locate the styled components ItemTitle, ChampDbTiltle, ChampSearchArea, and Wrapper, then inspect the Item DB and Champ DB layouts at desktop and narrow screen sizes. Apply the requested CSS corrections for margins, font size, button padding, and mobile spacing; the issue does not specify the replacement values, so confirm the intended appearance before starting.
