The plugin doesn’t works in responsive mode

I install the plugin with the following code:

<div class=”embed-container”>
[wp-flowplus ngg_icd=1 startimg=2 style=baseline]
</div>

but I Can’t see it in responsive mode I’d tried to put this code in the css file but it’s the same error:

.wpif2_image_block { overflow: visible; }
.wpif2_images img { margin-top: -50%; }

What can I do to fix this?

Here’s the link where I’m testing the plugin
