Grid-Based Sidebar Layout
CSS Grid provides a powerful and flexible way to create sidebar layouts.
This approach uses grid-template-columns to define the sidebar
width and main content area.
Implementation
.sidebar-grid {
display: grid;
grid-template-columns: 250px 1fr;
}
.sidebar-grid.right {
grid-template-columns: 1fr 250px;
}
Key Features
- Fixed sidebar width with flexible main content
- Easy to switch sidebar position
- Clean, declarative syntax
- Works well with sticky positioning
- Responsive with media queries
Advantages of Grid
Grid excels at creating two-dimensional layouts. It's particularly good for
sidebar layouts because you can easily control both the sizing and positioning
of elements. The fr unit makes the main content area automatically
fill available space.
The grid approach also makes it simple to add gaps between columns and handle responsive behavior. You can easily switch from a two-column layout to a single column on mobile devices.
