Edit: seems like it depends on how much you zoom you browser. If I zoom out so I can see multiple profile pictures as the latest posters, it looks good. But when I zoom in enough to only see the single latest poster in a thread, it’s offset. Same in Opera and Firefox
The CSS. I just talked about the pixel values as that is what I was tweaking.
I didn’t write the CSS myself, nor am I very good at it, so I usually keep to just tweaking numbers and other simple things.
