I installed 'Thank you plugin' but the button on my test site but the button looks strange.
I found why. Because it inherits #commentform textarea { width: 45%;} from my theme. If I remove the width from css the button looks ok. Any idea how I can fix that? Of course I do not want to remove width for #commentform textarea. Can I do something about that on css level of the button? Something like with:not-inherit; width:reset; ? I'd say that the width of the button wouldn't be declared at all if there was no #commentform textarea
