sticky column

hi,

i’am creating a two-columned post with this plugin, with text on one column and image on the other.

i’d like to make when one of the two columns reaches the bottom of its own column, it gets stciky, while the other column will continue to scroll until it gets to its own column bottom.

can this be possible with some css tricks? i tried with “position: sticky” but it didn’t work.

thank you!
