Please, I still need help for my problem.
See my previous post.

Thanks but this code does some weird things.

1. The border appears but not everywhere in the same thickness. The elements on the right side don’t have a border at all on their respective right side.
2. The last two images where moved one spot to the right. So now the empty field is on the lower left corner instead of the lower right as it was before.
3. The border doesn’t seem to be equally aligned throughout the gallery.

Is there another possibility to archive even borders on every image?

Geat! That did the trick. Thanks a lot!

Now I got one more for you guys:
How do I give the masonry gallery elements (the portfolio images) a slight thin border? I don’t mean the “gap” option inside the masonry gallery settings. I chose the “1 pixel gap” which is fine for me. But now I want the elements itself to have a thin grey border.

For example:
When you look at my website, the last picture on the bottom (the one with the girl and the shadow on the wall) blends from the white on the right side of the picture into the white of the background. I need a slight border/line that really separates it from the background. I want this to be around every image/portfolio item.

@Ismael:
hahah nice … and I hope everyone agreed with you :)

Thanks for your reply.
I’ve added the code to the quick CSS but nothing changed so far.
