@crzymnmchl Thanks for reading! I also had the same trouble as you stacking the flip and rotate classes on the same Fontawesome icon. But you should be able to do this by combining a Fontawesome class and custom css. You could handle the flip with a class —
<i class=”fa fa-bar-chart fa-flip-horizontal”></i>
Then in your CSS file select the icon and apply a transform of type rotate —
-ms-transform: rotate(30deg); /* IE 9 */
-webkit-transform: rotate(30deg); /* Chrome, Safari, Opera */
I tested that and it works in Chrome. You can of course specify the degrees you need in the CSS. I don’t love the selector for that CSS, and I’m sure you could improve it.
