< p > The above example creates three equal-width columns on small, medium, large, and extra large devices using our predefined grid classes. Those columns are centered in the page with the parent < code class = "highlighter-rouge" > .container< / code > .< / p >
< p > Breaking it down, here’ < / p >
< ul >
< li > Containers provide a means to center your site’ < code class = "highlighter-rouge" > .container< / code > for fixed width or < code class = "highlighter-rouge" > .container-fluid< / code > for full width.< / li >
< li > Rows are horizontal groups of columns that ensure your columns are lined up properly. We use the negative margin method on < code class = "highlighter-rouge" > .row< / code > to ensure all your content is aligned properly down the left side.< / li >
< li > Content should be placed within columns, and only columns may be immediate children of rows.< / li >
< li > Thanks to flexbox, grid columns without a set width will automatically layout with equal widths. For example, four instances of < code class = "highlighter-rouge" > .col-sm< / code > will each automatically be 25% wide for small breakpoints.< / li >
< li > Column classes indicate the number of columns you’ < code class = "highlighter-rouge" > .col-sm-4< / code > .< / li >
< li > Column < code class = "highlighter-rouge" > width< / code > s are set in percentages, so they’ < / li >
< li > Columns have horizontal < code class = "highlighter-rouge" > padding< / code > to create the gutters between individual columns, however, you can remove the < code class = "highlighter-rouge" > margin< / code > from rows and < code class = "highlighter-rouge" > padding< / code > from columns with < code class = "highlighter-rouge" > .no-gutters< / code > on the < code class = "highlighter-rouge" > .row< / code > .< / li >
< li > There are five grid tiers, one for each < a href = "/docs/4.0/layout/overview/#responsive-breakpoints" > responsive breakpoint< / a > : all breakpoints (extra small), small, medium, large, and extra large.< / li >
< li > Grid tiers are based on minimum widths, meaning they apply to that one tier and all those above it (e.g., < code class = "highlighter-rouge" > .col-sm-4< / code > applies to small, medium, large, and extra large devices).< / li >
< li > You can use predefined grid classes or Sass mixins for more semantic markup.< / li >

< p > Equal-width columns can be broken into multiple lines, but there is a < a href = "https://github.com/philipwalton/flexbugs#11-min-and-max-size-declarations-are-ignored-when-wrapping-flex-items" > Safari flexbox bug< / a > that prevents this from working without an explicit < code class = "highlighter-rouge" > flex-basis< / code > or < code class = "highlighter-rouge" > border< / code > . Our example works thanks to the < code class = "highlighter-rouge" > border< / code > being set; you can do the same with < code class = "highlighter-rouge" > .col { border: 1px solid transparent; }< / code > . Alternatively, you can set the flex-basis to the width of the column (e.g., < code class = "highlighter-rouge" > .col { flex: 1 0 50%; }< / code > ).< / p >
