Does anyone know how to make Card2 and Card3 in Bootstrap4 stretch to 100% width? Card1 defines the total height, but Card2 and Card3 are not taking up the full remaining width. Card1 is already stretched, but Card2 and Card3 are inside a flex column and are not stretching. Any suggestions on how to make them stretch?
