CSS Grid

1. What is CSS Grid?

CSS Grid Layout is a layout method that allows you to arrange elements in rows and columns. It offers a more efficient way to design responsive layouts compared to traditional CSS methods, like flexbox and floats.

2. Creating a Basic Grid

To create a grid, you need to set the display property of a container to grid:

Edit Copy

container {
    display: grid;
    grid-template-columns: repeat(3, 1fr);
    grid-gap: 10px;
}

This example creates a grid with three equal columns and a gap of 10 pixels between grid items.

3. Defining Grid Template Areas

You can also define grid areas for a more organized layout. Here's how to do it:

Edit Copy

container {
    display: grid;
    grid-template-areas: 
        'header header header'
        'main sidebar sidebar'
        'footer footer footer';
}

In this example, we have defined a grid layout with header, main, sidebar, and footer areas.

4. Placing Items in the Grid

You can place grid items in specific areas defined by grid-template-areas:

Edit Copy

header {
    grid-area: header;
}
main {
    grid-area: main;
}
sidebar {
    grid-area: sidebar;
}
footer {
    grid-area: footer;
}

This allows you to control where each item will be displayed within the grid.

5. Responsive Grid Layouts

CSS Grid is inherently responsive. You can change the grid layout based on screen size using media queries:

Edit Copy

@media (max-width: 600px) {
    container {
        grid-template-columns: 1fr;
        grid-template-areas: 
            'header'
            'main'
            'sidebar'
            'footer';
    }
}

This example changes the grid layout to a single-column layout on smaller screens.

6. Example: Complete Grid Layout

Here’s a complete example demonstrating a responsive grid layout:

Edit Copy

.container {
    display: grid;
    grid-template-columns: repeat(3, 1fr);
    grid-gap: 20px;
    grid-template-areas: 
        'header header header'
        'main sidebar sidebar'
        'footer footer footer';
}

.header {
    grid-area: header;
}

.main {
    grid-area: main;
}

.sidebar {
    grid-area: sidebar;
}

.footer {
    grid-area: footer;
}

Using this setup, you can create a structured and adaptable web page layout.
