In the linked/related questions sidebar, there is an icon inconsistency. Questions with an accepted answer have a (green) hexagonal icon, and questions without an accepted answer have a (grey) rectangular icon. Is this a bug?
From the source of the webpage, we see that the accepted answer divs have the class
<div class="answer-votes answered-accepted default">8</div>
If one looks more closely at the image which is used as the background image for the class
answered-accepted we find that it is the following:
Those on other sites do not have the hexagons, (at least not on Maths.SE) which may be to give a futuristic look to our site. As we are SFF.SE after all and sci-fi is a major part of our agenda.
The non-accepted answers have the class
<div class="answer-votes default">5</div>
With no background image.
