Card component (desktop design) using flexbox

Hello guys,

I'm proud of my work but I had some difficulties. I didn't succeed/manage to position the text perfectly where I wanted. For example, the 3 components on the bottom are taking more space on the right than the main title. I don't know why, a problem with the font (size, family, weight)? A problem witht the padding/margin ?

Thank you everyone and happy coding !
