So, if you want three equal-width columns across, you can use. Column classes indicate the number of columns you’d like to use out of the possible 12 per row.See the auto-layout columns section for more examples. col-sm will each automatically be 25% wide from the small breakpoint and up. Thanks to flexbox, grid columns without a specified width will automatically layout as equal width columns.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. Containers provide a means to center and horizontally pad your site’s contents.Those columns are centered in the page with the parent. Use these row columns classes to quickly create basic grid layouts or to control your card layouts.The above example creates three equal-width columns on small, medium, large, and extra large devices using our predefined grid classes. row-cols-auto you can give the columns their natural width. col-md-4), the row columns classes are set on the parent. col-* classes apply to the individual columns (e.g.
row-cols-* classes to quickly set the number of columns that best render your content and layout. Here’s how the grid changes across these breakpoints: The six default grid tiers are as follows:Īs noted above, each of these breakpoints have their own container, unique class prefix, and modifiers. Grid optionsīootstrap’s grid system can adapt across all six default breakpoints, and any breakpoints you customize. We also include some CSS custom properties to consume these Sass variables for even greater flexibility for you.īe aware of the limitations and bugs around flexbox, like the inability to use some HTML elements as flex containers. If you don’t want to use the predefined grid classes in Bootstrap, you can use our grid’s source Sass to create your own with more semantic markup. Sass variables, maps, and mixins power the grid. g-* classes.g-0 is also available to remove gutters. Gutter classes are available across all breakpoints, with all the same sizes as our margin and padding spacing. Gutters are also responsive and customizable. widths are set in percentages so you always have the same relative sizing. Column classes indicate the number of template columns to span (e.g., col-4 spans four). There are 12 template columns available per row, allowing you to create different combinations of elements that span any number of columns. Rows also support modifier classes to uniformly apply column sizing and gutter classes to change the spacing of your content.Ĭolumns are incredibly flexible. This padding is then counteracted on the rows with negative margins to ensure the content in your columns is visually aligned down the left side. container-md) for a combination of fluid and pixel widths. container-fluid for width: 100% across all viewports and devices, or a responsive container (e.g. This means you can control container and column sizing and behavior by each breakpoint.Ĭontainers center and horizontally pad your content. col-sm-4 applies to sm, md, lg, xl, and xxl). Breakpoints are based on min-width media queries, meaning they affect that breakpoint and all those above it (e.g. Our grid supports six responsive breakpoints. How it worksīreaking it down, here’s how the grid system comes together: The above example creates three equal-width columns across all devices and viewports using our predefined grid classes.
