I am using the latest version of holder.js from here
How ever if I try to use percentage for the width like
<img data-src="holder.js/100%x380" class="img-responsive">
Does not work. In older version it did but not in current versions
Question How can I make holder.js use % for width in latest versions?
I have found how to get full width with latest version of holder js
Instead of
%
usepx
like100 for full width and then you can have any height your after.
