It’s not a problem with the label or the plugin, it’s displayed the way it is on the website you linked above.
I was just wondering if there is a way to resize it so that it fits in with my website a little bit better. I think that’s what the OP was asking as well. If there’s a way to customise it, since we all have different layouts/themes and one size may not fit all. Some of us have websites with smaller fonts and post sizes, so it would be great if the label could match our style as well. A way to adjust the width and height of the label for example would help a lot.
