Description

The grid-area CSS property is a shorthand that allows you to define the size and location of a grid item within a grid layout. This property combines several grid-related properties into one, making it easier to manage the placement and dimensions of grid items.

By using grid-area, you can specify the starting and ending lines for both rows and columns, or assign a name to the grid item. This flexibility makes it a versatile tool for creating complex and responsive grid layouts.

Whether you need to position a grid item precisely or define named areas for easier reference, grid-area simplifies the process and enhances the readability of your CSS code. This property is particularly useful for web designers and developers who aim to create clean, maintainable, and visually appealing grid layouts.

Setting Grid Areas

Setting grid areas with the grid-area property involves defining the positions and sizes of grid items within a grid container. This property allows you to specify the starting and ending lines for both rows and columns, making it easy to control the layout of your grid items.

Basic Syntax

The basic syntax for the grid-area property is as follows:

grid-area: grid-row-start / grid-column-start / grid-row-end / grid-column-end;

Here’s what each part of the syntax represents:

• grid-row-start: The starting row line for the grid item.
• grid-column-start: The starting column line for the grid item.
• grid-row-end: The ending row line for the grid item.
• grid-column-end: The ending column line for the grid item.

Example

Let’s look at a simple example to understand how grid-area works.

HTML

<div id="grid">
  <div id="item1"></div>
  <div id="item2"></div>
  <div id="item3"></div>
</div>

CSS

#grid {
  display: grid;
  height: 200px;
  grid-template: repeat(4, 1fr) / 50px 100px;
}

#item1 {
  background-color: lime;
  grid-area: 2 / 2 / auto / span 3;
}

#item2 {
  background-color: yellow;
}

#item3 {
  background-color: blue;
}

In this example:

• The grid-area property for #item1 is set to 2 / 2 / auto / span 3.
• This means that #item1 starts at row 2 and column 2, spans automatically to the next row, and spans across 3 columns.

Named Grid Areas

You can also use grid-area to define named areas in a grid layout. This is done using the grid-template-areas property in conjunction with grid-area.

HTML

<div id="grid">
  <div id="header"></div>
  <div id="sidebar"></div>
  <div id="main"></div>
  <div id="footer"></div>
</div>

CSS

#grid {
  display: grid;
  grid-template-areas:
    "header header header"
    "sidebar main main"
    "footer footer footer";
  grid-gap: 10px;
}

#header {
  grid-area: header;
  background-color: lightblue;
}

#sidebar {
  grid-area: sidebar;
  background-color: lightcoral;
}

#main {
  grid-area: main;
  background-color: lightgreen;
}

#footer {
  grid-area: footer;
  background-color: lightyellow;
}

In this example:

• The grid-template-areas property defines the layout of the grid, specifying named areas like header, sidebar, main, and footer.
• The grid-area property is then used to place the grid items into these named areas.

Setting grid areas with the grid-area property provides a flexible and intuitive way to manage grid layouts, making it a valuable tool for web developers and designers.

Properties of grid-area

The grid-area CSS property is a shorthand that combines several individual properties into one, making it easier to manage the placement and dimensions of grid items. This section outlines the constituent properties that grid-area encompasses.

Constituent Properties

The grid-area property is a shorthand for the following CSS properties:

1. grid-row-start: Specifies the starting row line for the grid item.
2. grid-column-start: Specifies the starting column line for the grid item.
3. grid-row-end: Specifies the ending row line for the grid item.
4. grid-column-end: Specifies the ending column line for the grid item.

How It Works

When you use the grid-area property, you can define the placement of a grid item by specifying up to four values. These values correspond to the grid-row-start, grid-column-start, grid-row-end, and grid-column-end properties, respectively.

Example

grid-area: 1 / 1 / 3 / 3;

In this example:

• 1 is the starting row line (grid-row-start).
• 1 is the starting column line (grid-column-start).
• 3 is the ending row line (grid-row-end).
• 3 is the ending column line (grid-column-end).

Default Values

If any of the values are omitted, they default to auto. This means that the grid item will be placed automatically based on the grid container’s layout.

Example with Default Values

grid-area: 1 / 1 / auto / auto;

In this case, the grid item will start at row 1 and column 1, and its ending lines will be determined automatically by the grid container.

Named Grid Areas

You can also use grid-area to assign a name to a grid item. This is particularly useful when using the grid-template-areas property to define named areas in your grid layout.

Example with Named Areas

grid-area: header;

In this example, the grid item is assigned to the named area header. This name can then be used in the grid-template-areas property to define the layout.

Summary

The grid-area property simplifies the process of defining the size and location of grid items by combining multiple properties into one. Whether you’re specifying precise grid lines or assigning named areas, grid-area offers a flexible and intuitive way to manage your grid layouts. This makes it an essential tool for web developers and designers looking to create sophisticated and responsive web designs.

Syntax

The grid-area CSS property uses a specific syntax to define the size and location of a grid item within a grid layout. This syntax allows you to specify the starting and ending lines for both rows and columns, making it easy to control the placement and dimensions of your grid items.

Basic Syntax

The basic syntax for the grid-area property is as follows:

grid-area: grid-row-start / grid-column-start / grid-row-end / grid-column-end;

Here’s what each part of the syntax represents:

• grid-row-start: The starting row line for the grid item.
• grid-column-start: The starting column line for the grid item.
• grid-row-end: The ending row line for the grid item.
• grid-column-end: The ending column line for the grid item.

Using Keyword Values

You can also use keyword values with the grid-area property to define the placement of grid items.

Example

grid-area: auto;
grid-area: auto / auto;
grid-area: auto / auto / auto;
grid-area: auto / auto / auto / auto;

In these examples, the auto keyword indicates that the property contributes nothing to the grid item’s placement, allowing for automatic placement or a default span of 1.

Using Custom Identifiers

The grid-area property can also be set to a custom identifier, which acts as a name for the area. This name can then be used with the grid-template-areas property to place the grid items.

Example

grid-area: some-grid-area;
grid-area: some-grid-area / another-grid-area;

In this example, the grid items are assigned to named areas some-grid-area and another-grid-area.

Using Integers and Custom Identifiers

You can combine integers and custom identifiers to specify the exact position and span of grid items.

Example

grid-area: 4 some-grid-area;
grid-area: 4 some-grid-area / 2 another-grid-area;

In these examples, the grid items are placed based on specific row and column lines, with optional spanning.

Using Span Values

The grid-area property also supports span values, which allow you to specify the number of rows or columns a grid item should span.

Example

grid-area: span 3;
grid-area: span 3 / span some-grid-area;
grid-area: 2 span / another-grid-area span;

In these examples, the grid items span a specified number of rows or columns.

Global Values

The grid-area property supports global values such as inherit, initial, revert, revert-layer, and unset.

Example

grid-area: inherit;
grid-area: initial;
grid-area: revert;
grid-area: revert-layer;
grid-area: unset;

These global values can be used to inherit styles from parent elements, reset to initial values, or revert to previous values.

Summary

The grid-area property provides a versatile syntax that allows you to define the size and location of grid items within a grid layout. Whether you’re using keyword values, custom identifiers, integers, or span values, grid-area offers a flexible and intuitive way to manage your grid layouts. This makes it an essential tool for web developers and designers looking to create sophisticated and responsive web designs.

Values

The grid-area CSS property accepts a variety of values that allow you to define the size and location of a grid item within a grid layout. These values include keywords, custom identifiers, integers, and span values. Understanding these values is crucial for effectively using the grid-area property.

Keyword Values

The grid-area property supports the following keyword values:

• auto: Indicates that the property contributes nothing to the grid item’s placement. This results in automatic placement or a default span of 1.

Custom Identifiers

You can use custom identifiers to assign a name to a grid area. This is particularly useful when defining named areas in your grid layout using the grid-template-areas property.

Example

grid-area: some-grid-area;
grid-area: some-grid-area / another-grid-area;

In these examples, the grid items are assigned to named areas some-grid-area and another-grid-area.

Note

Named grid areas automatically generate implicit named lines of the form <custom-ident>-start and <custom-ident>-end. Therefore, specifying grid-area: foo; will choose the start/end edge of the named grid area foo unless another line named foo-start/foo-end is explicitly specified before it.

Integers and Custom Identifiers

You can combine integers and custom identifiers to specify the exact position and span of grid items.

Example

grid-area: 4 some-grid-area;
grid-area: 4 some-grid-area / 2 another-grid-area;

In these examples, the grid items are placed based on specific row and column lines, with optional spanning.

Span Values

The grid-area property also supports span values, which allow you to specify the number of rows or columns a grid item should span.

Example

grid-area: span 3;
grid-area: span 3 / span some-grid-area;
grid-area: 2 span / another-grid-area span;

In these examples, the grid items span a specified number of rows or columns.

Global Values

The grid-area property supports global values such as inherit, initial, revert, revert-layer, and unset.

Example

grid-area: inherit;
grid-area: initial;
grid-area: revert;
grid-area: revert-layer;
grid-area: unset;

These global values can be used to inherit styles from parent elements, reset to initial values, or revert to previous values.

Summary

The grid-area property provides a versatile way to define the size and location of grid items within a grid layout. By using keyword values, custom identifiers, integers, and span values, you can precisely control the placement and dimensions of your grid items. This makes grid-area an essential tool for web developers and designers looking to create sophisticated and responsive web designs.

The grid-area Property

The grid-area property in CSS is a powerful tool for defining the size and location of grid items within a grid layout. It’s essential for creating sophisticated and responsive web designs.

Examples

Let’s explore some practical examples to see how grid-area can be used:

Example 1: Specifying Grid Area Position

In this example, we create a grid with one named area “Area” spanning three columns using grid-area. Other items fill the remaining cells.

HTML

<!DOCTYPE html>
<html>
<head>
    <title>CSS grid-area Property</title>
    <style>
        .item {
            grid-area: Area;
        }

        .grid-container {
            display: grid;
            grid-template-areas: 'Area Area Area';
            grid-gap: 30px;
            background-color: green;
            padding: 20px;
        }

        .GFG {
            background-color: white;
            text-align: center;
            padding: 20px 0;
            font-size: 30px;
        }
    </style>
</head>
<body>
    <h1>Website</h1>
    <h2>The grid-area Property</h2>

    <div class="grid-container">
        <div class="GFG item">1</div>
        <div class="GFG">2</div>
        <div class="GFG">3</div>
        <div class="GFG">4</div>
        <div class="GFG">5</div>
        <div class="GFG">6</div>
    </div>
</body>
</html>

In this example, the grid-area property defines a named area called “Area” that spans three columns. Other grid items fill the remaining cells with specific styling.

Example 2: Naming a Grid Item

In this example, we use grid-area to define named areas in a grid layout. Each area is styled with specific content alignment and size.

HTML

<!DOCTYPE html>
<html>
<head>
    <title>CSS grid-area Property</title>
    <style>
        .GFG1 {
            grid-area: heading;
        }

        .GFG2 {
            grid-area: margin;
        }

        .GFG3 {
            grid-area: subtitle1;
        }

        .GFG4 {
            grid-area: info;
        }

        .main {
            display: grid;
            grid-gap: 30px;
            background-color: green;
            padding: 20px;
            grid-template-areas:
                'margin heading heading heading heading heading'
                'margin subtitle1 info info info info';
        }

        .GFG {
            background-color: white;
            text-align: center;
            padding: 20px 0;
            font-size: 30px;
        }
    </style>
</head>
<body>
    <h1>Website</h1>
    <h2>CSS grid-area Property</h2>

    <div class="main">
        <div class="GFG GFG1">Heading</div>
        <div class="GFG GFG2">Margin</div>
        <div class="GFG GFG3">Subtitle</div>
        <div class="GFG GFG4">info</div>
    </div>
</body>
</html>

In this example, the grid-area property is used to define named areas such as “heading,” “margin,” “subtitle1,” and “info.” The grid-template-areas property defines the layout of the grid, and the grid-area property places the grid items into these named areas.

Example 3: Defining Grid Areas with Span Values

In this example, we use grid-area to define a grid area that spans multiple rows and columns using span values.

HTML

<!DOCTYPE html>
<html>
<head>
    <title>CSS grid-area Property</title>
    <style>
        .grid-container {
            display: grid;
            height: 200px;
            grid-template: repeat(4, 1fr) / 50px 100px;
        }

        #item1 {
            background-color: lime;
            grid-area: 2 / 2 / auto / span 3;
        }

        #item2 {
            background-color: yellow;
        }

        #item3 {
            background-color: blue;
        }
    </style>
</head>
<body>
    <h1>Website</h1>
    <h2>The grid-area Property</h2>

    <div class="grid-container">
        <div id="item1"></div>
        <div id="item2"></div>
        <div id="item3"></div>
    </div>
</body>
</html>

In this example, the grid-area property for #item1 is set to 2 / 2 / auto / span 3. This means that #item1 starts at row 2 and column 2, spans automatically to the next row, and spans across 3 columns.
