阅读更多关于 Bootstrap 4 alpha 6 nav-tabs align item right

I am trying to create a tab menu that has nav-item dropdown to the far right of the menu. Bootstrap 4 alpha 5, with float-xs-right its working: http://codeply.com/go/FCFPpRqhZd Bootstrap 4 alpha 6, i changed to float-right but it isnt working: http://codeply.com/go/5mddDUv1M6 Have idea? Since alpha 6 is now flexbox, float will no longer work in this case. Use the ml-auto utility class instead for margin-left:auto <div class="col-md-12"> <ul class="nav nav-tabs"> <li class="nav-item"> <a href="#" class="nav-link active">Link 1</a> </li> <li class="nav-item"> <a href="#" class="nav-link">Link 2<

Is there really no way to wrap text around an image in flexbox?

阅读更多关于 Is there really no way to wrap text around an image in flexbox?

Normally when you have a block of text you can just float the image left or right to wrap the text around it, but in flexbox floats do not work and I am struggling to find a solution. Bootstrap 4 is going to use flexbox for their new grid system but this might be a deal breaker if you can't have a block of text in a column and also have text wrap around an image.

This question already has an answer here: `col-xs-*` not working in Bootstrap 4 2 answers In my react project, using react-bootstrap, it's loading all all the css for the grid sizes, except for the xs set. the xs set does, however, get the default styles applied to all grid sizes, but does not include the media query.

Since Bootstrap is "mobile first", the xs breakpoint (<576px) is the default and are no media queries for it.
