To make the grid responsive, there are five grid breakpoints, one for each responsive breakpoint: all breakpoints (extra small), small, medium, large, and extra large.Columns have horizontal padding to create the gutters between individual columns, however, you can remove the margin from and padding from by setting the no-gutters prop on.Column widths are set in percentages, so they're always fluid and sized relative to their parent element.the special value auto can be used to take up the remaining available column space in a row. So, if you want three equal-width columns at breakpoint sm, you can use. Column props sm, md, lg, xl indicate the number of columns you'd like to use out of the possible 12 per row, at the various breakpoints.So, if you want three equal-width columns at any breakpoint, you can use. Column prop cols indicates the number of columns you'd like to use out of the possible 12 per row regardless of breakpoint (starting at breakpoint xs).For example, four instances of will each automatically be 25% wide for small breakpoints. Thanks to flexbox, grid columns without a set width will automatically layout with equal widths.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.

Use for a responsive pixel width or for width: 100% across all viewport and device sizes. Containers provide a means to center and horizontally pad your site's contents.Those columns are centered in the page with the parent. When I add flex-wrap they align to the center and I can’t understand why.The above example creates three equal-width columns on small, medium, large, and extra large devices using Bootstrap v4's predefined grid classes. I have a container, 4 items with align-items to flex-end putting them at the bottom of the page. Hi, I’m getting quite confuse by the action of flex-wrap on align-items.
