Why can't I center my button in media queries

So I made two buttons in a grid, and in order for them to sit closer to each other I use justify-self: start and justify-self: end to the buttons. Everything works just fine until I made a media queries. These two buttons won't center themselves even though I have set them to center.

I want these two buttons be on the center in media queries. I have tried using justify-self: center, but it didn't work.

Solution

  • The issue in your code is you are trying to apply justify-self: center to the a tags directly, while it should be applied to grid items directly. Also, you have wrapped the buttons inside a div which is a grid item.

    Tweak your media query as follows and confirm it works:

    @media (max-width: 768px) {
  .showcase {
    height: auto;
  }

  .grid,
  .showcase .grid {
    grid-template-columns: 1fr;
    grid-template-rows: auto auto;
  }

  .showcase .grid div {
    justify-self: center;
  }
}

    Here, we adjust the grid-template-columns and grid-template-rows to 1fr and auto auto, respectively, to ensure each button container takes full width and aligns in the center.We also apply justify-self: center to the div containers within the grid to center align the buttons within those containers.
