Cannot center vertically in layout grid

[benkn]

I have an object that i want within a layout grid, but it always goes to the top by default.

If I click options on the layout grid, the vertical align option is greyed out.

Vertical alignment only is available if the grid system is set to 'flexbox'. See also the information in the help.

I have made transparent images of the size required to position elements within a layout grid before. (I use the free image program GIMP and export as .png. Just a blank rectangle (or one the same color as the background) dropped into the cell next to or above/below the element you are trying to position. Be careful with this method because in responsive designs the blank image may render differently and break your layout. Just a suggestion, Pablo's answers are more reliable than mine for sure!
