This, in conjunction with [horizontal alignment](#horizontal-alignment) classes, is very useful for centering layouts with uneven column sizes as viewport width grows. + +<div class="bd-example-row"> +{% example html %} +<div class="container"> + <div class="row flex-items-md-center"> + <div class="col-xs col-lg-2"> + 1 of 3 + </div> + <div class="col-xs-12 col-md-auto"> + Variable width content + </div> + <div class="col-xs col-lg-2"> + 3 of 3 + </div> + </div> + <div class="row"> + <div class="col-xs"> + 1 of 3 + </div> + <div class="col-xs-12 col-md-auto"> + Variable width content + </div> + <div class="col-xs col-lg-2"> + 3 of 3 + </div> + </div> +</div> +{% endexample %} +</div> + ## Responsive flexbox Unlike the default grid system, the flexbox grid requires a class for full-width columns. If you have a `.col-sm-6` and don't add `.col-xs-12`, your `xs` grid will not render correctly. Note that flexbox grid tiers still scale up across breakpoints, so if you want two 50% wide columns across `sm`, `md`, and `lg`, you only need to set `.col-sm-6`. |
