In testing I found the following not to work any longer in Blocs 3.1.
I have an imbedded excel spread sheet using an iframe in an HTML bric which I wanted to make responsive and I had wrapped with the following:
div class=“embed-responsive embed-responsive-4by3”>
<iframe class="embed-responsive-item" width="980" height="500" frameborder="0" scrolling="no"
Work great in Blocs 3.0.7 now all I see is a blank page where the spread sheet should be. I guess the newer version of bootstrap works differently.
Any ideas on how to fix this bric or make an iframe responsive with the new version of bootstrap?
Update: I found this in Bootstrap Doc, which seems to say it should still work as before?
For what it is worth when I open the 3.1 copy of the project file with 3.07 it not longer works as well.
