CSS Grid

CSS Grid is a powerful layout model that allows developers to create complex grid-based layouts with rows and columns. Unlike traditional layout methods like floats and positioning, CSS Grid is specifically designed for creating multi-dimensional layouts.

1. The Grid Container and Grid Items: In CSS Grid, you work with two main components: the grid container and grid items. The grid container is an HTML element that becomes a grid by setting its display property to grid. All direct children of the grid container automatically become grid items.

2. Defining the Grid Structure: CSS Grid uses the grid-template-columns and grid-template-rows properties to define the size and number of columns and rows in the grid. You can specify the size of each column or row using fixed values (e.g., 100px) or flexible units (e.g., 1fr).

3. Placing Grid Items: Grid items can be placed explicitly using the grid-row and grid-column properties or implicitly by letting CSS Grid automatically place items based on their order in the HTML markup. The grid-area property allows you to create named grid areas, which is particularly useful for complex layouts.

4. Grid Gaps: CSS Grid allows you to add gaps between rows and columns using the grid-gap property. This makes it easy to create consistent spacing and visually appealing designs.

5. Grid Alignment and Justification: CSS Grid provides properties like justify-items, align-items, justify-content, and align-content to control the alignment of grid items within their cells and the alignment of the grid within the grid container.

6. Grid Auto Placement and Sizing: CSS Grid offers auto-placement, where grid items are automatically placed in available cells without the need for explicit placement. Additionally, you can use the grid-auto-rows and grid-auto-columns properties to define the size of automatically created rows and columns.

7. Media Queries and Responsive Grids: CSS Grid seamlessly integrates with media queries, making it easy to create responsive layouts that adapt to different screen sizes and devices. By adjusting the grid structure and item placement within media queries, you can create versatile and adaptive designs.

8. Browser Support: CSS Grid is well-supported in modern browsers, including most recent versions of popular browsers, making it a reliable choice for building modern web layouts.

Let's create a simple example of using CSS Grid to create a basic two-column layout with some content.

  <link rel="stylesheet" href="styles.css">
  <div class="grid-container">
    <div class="item">1</div>
    <div class="item">2</div>
    <div class="item">3</div>
    <div class="item">4</div>
    <div class="item">5</div>
    <div class="item">6</div>

CSS (styles.css):

cssCopy codebody {
  margin: 0;
  font-family: Arial, sans-serif;

.grid-container {
  display: grid;
  grid-template-columns: 1fr 1fr; /* Two equal-width columns */
  grid-gap: 10px; /* Gap between grid items */
  padding: 20px; /* Padding around the grid container */

.item {
  background-color: #f0f0f0;
  padding: 20px;
  text-align: center;


  • We create a simple HTML file with a grid-container div that contains six item divs.

  • In the CSS, we set the display property of the grid-container to grid to make it a grid container.

  • We use grid-template-columns to create two columns of equal width using the 1fr unit, which means they share the available space equally.

  • grid-gap sets the gap between grid items to 10px.

  • padding adds some space around the grid container to make it look visually appealing.

  • Each item div is styled with a light gray background color, padding, and centered text.
