CSS Grid is a powerful layout system that has revolutionized the way we design and structure web pages. With its intuitive syntax and flexible capabilities, CSS Grid empowers front-end developers to create complex and responsive layouts with ease. In this article, we will explore the basics of CSS Grid and showcase examples of layouts that can be achieved using this amazing tool.

Understanding CSS Grid#Section titled Understanding CSS Grid

CSS Grid works by dividing a web page into a grid of rows and columns, allowing you to precisely position and align elements within the grid cells. It introduces two primary components: the parent container (grid container) and its child elements (grid items). Let’s dive into the key concepts of CSS Grid:

• Grid Container: The parent element that establishes the grid context. You can apply display: grid to any container to activate CSS Grid.
• Grid Items: The child elements of the grid container that are placed inside the grid cells. These items can be explicitly placed or allowed to flow automatically within the grid.
• Grid Lines: The horizontal and vertical lines that divide the grid into rows and columns, forming grid tracks.
• Grid Tracks: The spaces between grid lines that define the size of rows and columns.
• Grid Areas: The rectangular areas formed by the intersection of grid rows and columns, enabling you to group and manipulate related grid items.

Now that we have a basic understanding of CSS Grid, let’s explore some practical examples to showcase its versatility.

Example Layouts with CSS Grid#Section titled Example Layouts with CSS Grid

Basic Grid#Section titled Basic Grid

In this example, we create a basic grid layout with three equally sized columns and a 10-pixel gap between grid items.

.grid-container {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-gap: 10px;
}

.grid-item {
  background-color: var(--surface-2);
  padding: 20px;
}

<div class="grid-container">
  <div class="grid-item">Grid Item 1</div>
  <div class="grid-item">Grid Item 2</div>
  <div class="grid-item">Grid Item 3</div>
  <div class="grid-item">Grid Item 4</div>
  <div class="grid-item">Grid Item 5</div>
  <div class="grid-item">Grid Item 6</div>
</div>

Responsive Grid#Section titled Responsive Grid

This layout demonstrates the power of CSS Grid in creating responsive designs. The repeat(auto-fit, minmax(250px, 1fr)) rule ensures that the grid adapts to the available space, with a minimum width of 250 pixels per column.

.grid-container {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(250px, 1fr));
  grid-gap: 20px;
}

<div class="grid-container">
  <div class="grid-item">Grid Item 1</div>
  <div class="grid-item">Grid Item 2</div>
  <div class="grid-item">Grid Item 3</div>
  <div class="grid-item">Grid Item 4</div>
  <div class="grid-item">Grid Item 5</div>
  <div class="grid-item">Grid Item 6</div>
</div>

Masonry Layout#Section titled Masonry Layout

The masonry layout is achieved by using repeat(auto-fill, minmax(200px, 1fr)) to create a flexible grid with columns of at least 200 pixels wide. The grid-row-end: span 2 rule makes certain grid items span across two rows, creating the irregular brick-like pattern.

.grid-container {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(200px, 1fr));
  grid-gap: 20px;
}

.grid-item {
  grid-row-end: span 2;
}

<div class="grid-container">
  <div class="grid-item">Grid Item 1</div>
  <div>Grid Item 2</div>
  <div class="grid-item">Grid Item 3</div>
  <div class="grid-item">Grid Item 4</div>
  <div>Grid Item 5</div>
  <div>Grid Item 6</div>
</div>

Holy Grail Layout#Section titled Holy Grail Layout

The Holy Grail layout is a classic example of a webpage with a header, footer, sidebar, and main content area. CSS Grid simplifies this complex layout by utilizing grid-column and grid-row properties to position each element within the grid cells.

.grid-container {
  display: grid;
  grid-template-columns: 200px 1fr 200px;
  grid-template-rows: auto 1fr auto;
  grid-gap: 20px;
}

.header,
.footer {
  grid-column: 1 / -1;
}

.sidebar {
  grid-row: 2;
}

.content {
  grid-column: 2 / -1;
  grid-row: 2;
}

<div class="grid-container">
  <div class="header">Header</div>
  <div class="sidebar">Sidebar</div>
  <div class="content">Content</div>
  <div class="footer">Footer</div>
</div>

Image Gallery#Section titled Image Gallery

This example showcases an image gallery with a responsive grid. By using aspect-ratio and overflow: hidden on grid items, we maintain the aspect ratio of images and prevent them from distorting.

.grid-container {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(200px, 1fr));
  grid-gap: 10px;
}

.grid-item {
  aspect-ratio: 1/1;
  overflow: hidden;
}

.grid-item img {
  width: 100%;
  height: 100%;
  object-fit: cover;
}

<div class="grid-container">
  <div class="grid-item">
    <img src="path/to/image1.jpg" alt="Image 1" />
  </div>
  <div class="grid-item">
    <img src="path/to/image2.jpg" alt="Image 2" />
  </div>
  <div class="grid-item">
    <img src="path/to/image3.jpg" alt="Image 3" />
  </div>
  <!-- Add more grid items as needed -->
</div>
