Learn CSS Grid the easy way

Introduction

This tutorial will guide you through the fundamentals of CSS Grid, simplifying its concepts and properties. By the end of this guide, you'll be able to create responsive grid layouts for your web projects without feeling overwhelmed by the complexity of CSS Grid.

Step 1: Declaring Display Grid

To start using CSS Grid, you need to declare it in your CSS.

• Select the container element that will hold your grid items.
• Apply the display: grid; property to this container.

.container {
    display: grid;
}

Step 2: Using the Gap Property

The gap property controls the space between grid items, making your layout more visually appealing.

• Add the gap property to your grid container to set the space between rows and columns.

.container {
    gap: 10px; /* Adjust the value as needed */
}

Step 3: Utilizing the Grid Inspector

Take advantage of browser developer tools to inspect your grid layout.

• Right-click on your grid container in the browser and select "Inspect."
• Use the grid inspector to visualize the grid lines, areas, and item placements.

Step 4: Determining Column Count

Decide how many columns your grid needs based on your design.

• Use the grid-template-columns property to define the number of columns and their sizes.

.container {
    grid-template-columns: repeat(3, 1fr); /* 3 equal columns */
}

Step 5: Omitting Row Declaration

Often, you won't need to declare rows explicitly. CSS Grid will automatically create rows based on the number of items.

• Just focus on defining columns, and rows will adjust accordingly.

Step 6: Spanning Columns

Sometimes, you may want a grid item to span multiple columns.

• Use the grid-column property to specify how many columns an item should span.

.item {
    grid-column: span 2; /* Spans across 2 columns */
}

Step 7: Placing Items in Specific Grid Areas

You can place items in specific areas of the grid for better control.

• Use the grid-area property or the grid-row and grid-column properties to position items.

.item {
    grid-row: 1;
    grid-column: 2;
}

Step 8: Working with Line Numbers

CSS Grid allows you to work with line numbers for precise control over item placement.

• Refer to grid lines in your CSS to place items exactly where you want them.

.item {
    grid-column: 1 / 3; /* Starts at line 1 and ends at line 3 */
}

Step 9: Implementing Media Queries

To ensure your grid is responsive, use media queries to adjust the layout for different screen sizes.

• Inside the media query, redefine the grid-template-columns for various breakpoints.

@media (max-width: 600px) {
    .container {
        grid-template-columns: 1fr; /* Stacks items on smaller screens */
    }
}

Step 10: Using Grid Template Areas

For a more visual layout, use grid-template-areas to define specific areas of your grid.

• Assign names to grid areas and use them in your item definitions.

.container {
    grid-template-areas
        "header header"
        "sidebar content"
        "footer footer";
}

.header {
    grid-area: header;
}

Step 11: Understanding Auto Columns and Rows

CSS Grid supports automatic sizing of columns and rows based on content.

• Use auto to let grid items dictate their size while keeping your layout responsive.

.container {
    grid-template-columns: auto auto; /* Columns adjust to content size */
}
