Grid Containers and Grid Items Tutorial
CSS Grid Layout is a powerful layout system that allows web developers to create complex and flexible grid-based layouts for their websites. It provides two fundamental components - Grid Containers and Grid Items. The container defines the grid context, while items are the children placed within the grid.
Grid Container
To create a grid layout, you first need to define a container using the display: grid; property on
the parent element. The container becomes the context within which its children are arranged in rows and columns.
You can customize the grid using various properties like grid-template-columns,
grid-template-rows, grid-gap, and more.
.grid-container {
display: grid;
grid-template-columns: 1fr 1fr 1fr;
grid-template-rows: 100px 200px;
grid-gap: 10px;
}
Grid Item
Each child element inside the grid container is known as a grid item. You can place grid items in specific positions within the grid using line numbers or named grid areas. Grid items can span multiple rows or columns, making it highly flexible for designing responsive layouts.
.grid-item {
grid-column-start: 1;
grid-column-end: 3;
grid-row-start: 1;
grid-row-end: 2;
}
Mistakes to Avoid
- Forgetting to set the
display: grid;property on the container. - Incorrectly defining grid column or row positions for grid items.
- Using fixed units instead of
fr(fractional units) for flexible grid layouts.
