I want my website to have fixed width on differents sizes, my layout :
(The 40px on both sides is for the pgn borders image.)
But the layout does not correspond to what i have written, the row is always full width.
Could you show me how to have a fixed 640px width for LG and MD sizes and a fixed 380px width for SM size.
Also i’m not sur i have done things correctly for what i want + the image borders, don’t hesitate to tell me if things could be improved.
