This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

Summary

The grid-template-areas CSS property specifies named grid areas.

Those areas are not associated with any particular grid item, but can be referenced from the grid-placement properties grid-row-start, grid-row-end, grid-column-start, grid-column-end, and their shorthands grid-row, grid-column, and grid-area.

Initial value	`none`
Applies to	grid containers
Inherited	no
Media	visual
Computed value	as specified
Animation type	discrete
Canonical order	the unique non-ambiguous order defined by the formal grammar

Syntax

/* Keyword value */
grid-template-areas: none;

/* <string> values */
grid-template-areas: "a b";
grid-template-areas: "a b b"
                     "a c d";

/* Global values */
grid-template-areas: inherit;
grid-template-areas: initial;
grid-template-areas: unset;

Values

none: The grid container doesn’t define any named grid areas.
<string>+: A row is created for every separate string listed, and a column is created for each cell in the string. Multiple named cell tokens within and between rows create a single named grid area that spans the corresponding grid cells. Unless those cells form a rectangle, the declaration is invalid.

Formal syntax

none | <string>+

Example

HTML

<section id="page">
  <header>Header</header>
  <nav>Navigation</nav>

                       "nav  foot";
  grid-template-rows: 50px 1fr 30px;
  grid-template-columns: 150px 1fr;
}
