The problem (i see) its because the margin top has a fixed value in the footer as follows:

In the other hand, the article is displaying as block wich means its container size (itself) is adjusted to fit with his siblings, but the content keeps their heights:

Middle card has the major height (the red block), meanwhile the other two (green blocks) has less but display grid adjust them to fit with one height

Additionally the article needs to be displayed as flex to take the "margin-top: auto" property correctly:

hope this will be useful to fix the problem
