Floatin box messes up right aligned images in post

Yep, it’s deffinitely the diggdigg-style.css. If I remove it in developer mode, the pictures align right correctly. It’s not enough to remove the share box, I have to remove that css too…

Okay, so for the dev:
Your dd_start class in diggdigg-style.css?ver=5.3.6 messes up my right aligned images in the post. I use the standard CSS for aligning pictures which is “img.alignright {float:right; margin:0 0 1em 1em}” for aligning right.
If in Chrome developer mode I remove the tag, my pictures finally appears in right format. Can you suggest a workaround for this or remove this class? I don’t even know what is it for…
