Question

Utilizing the `repeat` function within `grid-template-areas` eliminates the need to manually repeat grid cell

When working with grid-template-areas in CSS grid, I encountered a situation where I wanted a header to span the entire width. Instead of defining the template-grid-columns with repeat(12, 1fr), I was searching for a way to utilize repeat() so that I wouldn't have to manually list the column name 12 times. Take a look at the example below.

grid-template-areas: 
            "article-hero article-hero article-hero article-hero article-hero article-hero article-hero article-hero article-hero article-hero article-hero article-hero"
            "header header header header header header header header header header header header"
            "main main main main main main main main main aside aside aside"
            "footer footer footer footer footer footer footer footer footer footer footer footer";

In the first row where 'article-hero' is repeated twelve times, I am wondering if there is a way to use repeat instead, such as repeat(12, article-hero), rather than manually repeating it 12 times?

When utilizing the grid-template-areas, it is essential to explicitly define the grid areas - there is no option for repeat as in ASCII art).

.wrapper {
  display: grid;
  grid-template-areas: "article-hero article-hero article-hero article-hero article-hero article-hero article-hero article-hero article-hero article-hero article-hero article-hero"
      "header header header header header header header header header header header header" 
      "main main main main main main main main main aside aside aside"
      "footer footer footer footer footer footer footer footer footer footer footer footer";
  height: 100vh;
}

.wrapper>* {
  border: 1px solid cadetblue;
}

article {
  grid-area: article-hero;
}

header {
  grid-area: header;
}

main {
  grid-area: main;
}

footer {
  grid-area: footer;
}

aside {
  grid-area: aside;
}

<div class="wrapper">
  <article>hero</article>
  <header>header</header>
  <main>main</main>
  <aside>aside</aside>
  <footer>footer</footer>
</div>

Some important points to remember when working with grid-template-areas:

The design should be rectangular in shape - check out this example here.
Ensure that the number of columns are consistent within each sequence specified in your grid-template-areas declaration - if they differ, the layout will not be valid - see an example here.

Aligning Items Using Grid Lines

You have the option to use line-based-placements here with a 12-column grid (employing

grid-template-columns: repeat(12, 1fr)

) and leveraging the grid-column property - see the demonstration below:

.wrapper {
  display: grid;
  grid-template-columns: repeat(12, 1fr);
  height: 100vh;
}
.wrapper>* {
  border: 1px solid cadetblue;
  grid-column: span 12;
}
.wrapper main {
  grid-column: span 9;
}
.wrapper aside {
  grid-column: span 3;
}

<div class="wrapper">
  <article>hero</article>
  <header>header</header>
  <main>main</main>
  <aside>aside</aside>
  <footer>footer</footer>
</div>
