How to center blocks in parent?

Question

css

Good afternoon, I encountered such a problem that on mobile devices and tablets, the blocks are displaced and an empty space appears as in the screenshot

. Is it possible to somehow center the blocks, if they are displaced, so that there is no "gap"?
Here is the css

spoiler

.section-quickSearch {
      max-width: @max-width;
      display: flex;
      flex-wrap: wrap;
      justify-content: center;
      margin: 0 auto;
      padding: 2.8125rem 0 0;
      border: 1px solid red;

      .quickSearchs {
        display: flex;
        flex-wrap: wrap;
        border: 1px solid green;

      .quickSearch-wrapper {
        display: flex;
        flex-wrap: wrap;
        justify-content: center;
        width: 18.75rem;
        margin-left: 1rem;
        margin-right: 1rem;
        margin-bottom: 2rem;
        background: #FCFCFC;
  }
 }
}

The ideal solution would be instead of justifu-content: flex-start; use justifu-content: center; but then the block is set to the center of the parent.
How can this problem be solved?

Found a solution
Green block (quickSearch), you need to add a pseudo element with a fixed width.

&:after {
  content: "";
  flex: 1 1 100%;
  max-width: 333px;
}
