    title=My First Tcolorbox,
    colback=blue!5!white,      % Background color (5% blue, 95% white)
    colframe=blue!75!black,    % Frame color (75% blue, 25% black)
    fonttitle=\bfseries,       % Bold font for the title
    boxsep=5mm,                % Space between box content and frame
    arc=4mm,                   % Rounded corners
    boxrule=1pt                % Thickness of the frame rule
