It is required to make a block in which only the two upper corners are curled. Rounded not evenly. Say 20px horizontally, 50 vertically. In this case, these values are specified through slash.
Works: non-uniform coordination for all angles at once:
Does not work: uneven skrgulenie upper corners in the general record:
border-radius: 20px/50px 20px/50px 0 0;
Does not work: uneven skrgulenie upper corners in the individual for each record:
border-top-left-radius: 20px/50px; border-top-right-radius: 20px/50px;
Tell me, please, what am I doing wrong?
