Why 3 elements with css property flex-wrap is transferred to a new line?

There are six elements that have the width of 33.33333%. Asked display: flex and flex-wrap: wrap, but instead of siting of 3 elements in a row, leaves only 2 elements in one row, and the rest migrated. Maybe something is wrong?

Solution
*, ::after, ::before {
 box-sizing: border-box;
}

Thank you very much, the mistake was a comma - Clovis.Frami14 commented on April 19th 20 at 12:09
