Four card feature section master Responsive with SASS and BEM

Hi everyone I have so much fun doing this project but I feel like I can do it better not using margin for the cards especially for set the image in the right place, If anyone know a better way to put the image without using margin I really appreciate it
I put the specific part of my code that I would like to have some feedback

.article {
  display: flex;
  flex-direction: column;
  padding: 1.875rem;
  padding-bottom: 1.25rem;
}
.article__h2 {
  font-size: 1.2em;
}
.article__p {
  font-size: 0.9em;
  margin-top: 0.25rem;
}
.article__img {
  align-self: flex-end;
  margin-top: 4rem;
  width: 3.4375rem;
}
