Study Notes
Bootstrap Grid System Overview
- Bootstrap's grid system provides a flexible layout structure using 12 columns.
- Layouts adapt to different screen sizes using responsive design principles.
Key Classes
.container
centers content and sets a maximum width..container-fluid
creates a full-width container..row
creates horizontal groups of columns..col-*
defines column widths across different screen sizes..g-*
adds spacing (gutters) between columns..offset-*
shifts columns to the right..order-*
changes the visual order of columns..align-items-*
aligns columns vertically..col-auto
sizes columns based on content..row-cols-*
defines the number of columns within each row..d-grid
creates a CSS grid layout.
Breakpoints
xs
applies to extra-small screens (phones).sm
applies to small screens (tablets).md
applies to medium screens (desktops).lg
applies to large screens (larger desktops).xl
applies to extra-large screens (very large desktops).
Important Behaviors
- If a row exceeds 12 columns, the extra columns wrap to the next line.
- The * in classes like
col-md-*
represents the number of columns to span. .col
makes all columns within a row have equal width.
