Any way to center childrens?

[h1sashin]

I tried using justify-content: space-around and center, doesn't work. Is there any prop that can center my divs?

this worked for me :

.container {
  width: 100%;

  .my-masonry-grid {
    display: flex;
    margin-left: -20px;
    width: 100%;

    .my-masonry-grid_column {
      display: flex;
      flex-direction: column;
      align-items: center;
      padding-left: 30px;
      background-clip: padding-box;
    }
  }
}

Correct, column alignment or children in the columns can be achieved with CSS flexbox rules
