In a grid layout, content must be placed within columns and only columns may be immediate children of rows. This way, all the content in your columns is visually aligned down the left side. This padding is then counteracted on the rows with negative margins. Each column has horizontal padding (called a gutter) for controlling the space between them. container-fluid for width: 100% across all viewport and device sizes. container for a responsive pixel width or. container.īreaking it down, here’s how it works:Ĭontainers provide a means to center and horizontally pad your site’s contents.

Need an edge-to-edge design? Drop the parent. While this generates a more specific selector, column padding can still be further customized with spacing utilities. Note that column overrides are scoped to only the first children columns and are targeted via attribute selector. Here’s the source code for creating these styles. row and the horizontal padding from all immediate children columns. The gutters between columns in our predefined grid classes can be removed with. Add any number of unit-less classes for each breakpoint you need and every column will be the same width. Equal-width įor example, here are two grid layouts that apply to every device and viewport, from xs to xl. ![]() Utilize breakpoint-specific column classes for easy column sizing without an explicit numbered class like. See how aspects of the Bootstrap grid system work across multiple devices with a handy table. This is because the viewport width is in pixels and does not change with the font size. While Bootstrap uses ems or rems for defining most sizes, pxs are used for grid breakpoints and container widths. col-4) or Sass mixins for more semantic markup.īe aware of the limitations and bugs around flexbox, like the inability to use some HTML elements as flex containers.
