Looking to display a specific email address mailbox for a project. The goal is to have the 'Mail Card List' scrollable instead of extending beyond the page. Tried using 'max-height:;' CSS, but it sets a fixed height. Seeking a variable height for adaptability to different screen sizes. Any tips on how to achieve this would be appreciated. Thank you.
