Auto-layout for flexbox Grid columns in ASP.Net

Auto-layout for flexbox grid columns also means you can lock the width of one column and have the sibling columns automatically resize around it. You can use predefined grid classes, grid mixins, or inline widths. Remark that the other columns will resize no matter the width of the center column.

I think i will have last column automatically = 4 if i have i column with div = 8.
