Vertical centering issue with CSS Grid

  • 772

Well, I can't vertically center a content using CSS Grid, with Flexbox I had no problems, I'm just starting with CSS Grid. This is what I have tried:

Use the classic method with transformand translateY:

.body {
  height: 100%;
}

.grid {
  position: relative;
  top: 50%;
  -webkit-transform: translateY(-50%);
  -ms-transform: translateY(-50%);
  transform: translateY(-50%);
}

I also tried using a container that wraps the grid like so:

.container {
  align-items: center;
  justify-content: center;
  height: 100%;
}

But none of this has worked for me.

What I want is to center the divwith class .gridrelative to the height of the device where the page loads (that's why I added the 100vhto body).

I share my code:

* {
  box-sizing: border-box;
}

body {
  color: white;
  font-size: 1rem;
  font-weight: 400;
  line-height: 1.5;
  align-items: center;
  margin: 2rem!important;
}

.grid {
  display: grid;
  grid-gap: 2rem;
  grid-template-columns: [inicio-contenido] 1fr [fin-contenido];
  grid-template-rows: auto [inicio-contenido] auto [fin-contenido];
}

@media (min-width: 640px) {
  .grid {
    grid-template-columns: 4fr [inicio-contenido] 4fr [fin-contenido];
  }
  header {
    grid-column: 1 / 3;
  }
  aside {
    grid-column: 1;
    grid-row: 2;
  }
  footer {
    grid-column: 1 / 3;
    grid-row: 3;
  }
}

article {
  grid-column: inicio-contenido;
  grid-row: inicio-contenido;
}

header,
aside,
article,
footer {
  background: #333;
  padding: 2rem;
  border-radius: .4rem;
}
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/normalize/5.0.0/normalize.min.css">

<body>

  <div class="grid">
    <header>Header</header>
    <aside>Aside</aside>
    <article>
      <h1>Mi título</h1>
      <p>Contenido cool</p>
    </article>
    <footer>Footer</footer>
  </div>

</body>

PS: For some reason, here in the snippet it is taking my styles first normalize.cssand not mine, I had to add the !importantbody for this reason.

I attach an image of what I want to achieve: Side A is what I currently have, side B is how I want it to be, centered depending on the height of the browser.

    Considers:

    • Use grid to set the structure of your grid
    • Use better flexbox for the alignment of the elements on one of its 2 axes

    You can build it this way.

    Process

    • To the parent label of divthe with the class , that is, apply a gridlabel , so that in this way its child node, which is the one with the class , becomes flexible and we can move it on one of the axes that make up the flexboxbodydisplay: flex;divgrid
    • That will momentarily move the layout of your divs leaving everything from one end, from left to right, since everything fits on the main axis

    Example

        <style>
      body{
        margin: 0px;
        display: flex;
        flex-direction: column;
        justify-content: center;
      }
      .grid {
        display: grid;
        grid-template-columns: repeat(2, 1fr);
      }
      header {
        grid-column: 1/3;
        background: grey;
      }
      aside {
        grid-column: 1/2;
        background: grey;
        margin-top: 10px;
        margin-right: 10px;
      }
      article {
        background: grey;
        margin-top: 10px;
      }
      footer {
        background: grey;
        margin-top: 10px;
        grid-column: 1/3;
      }
    </style>
    <body>
    
      <div class="grid">
        <header>Header</header>
        <aside>Aside</aside>
        <article>
          <h1>Mi título</h1>
          <p>Contenido cool</p>
        </article>
        <footer>Footer</footer>
      </div>
    
    </body>

    Note: Try this code in some system like JS Fiddle so you can better see how it works

    I add the snnipet with the example

  2. Try putting vertical centering on the particular container tag via CSS:

    .centrado {vertical-align: middle;display:inline;}

<div class="grid">
<header>Header</header>
<aside>Aside</aside>
<article>
<div class="centrado">
<h1>Mi título</h1>
<p>Contenido cool</p>
</div>
</article>
<footer>Footer</footer>
</div>
