Need some advise with my forum's CSS (SMF)

I’m attaching a file where I showed what exactly that I want to achieve.
As you can see…I have a post separator (a thick light blue bar - No. 2 on the picture).
I CAN make it somewhat narrower, but I prefer not to…
Now…As you can see on that print screen picture, where it says No. 1 and No.3…
There’re just few pixels space (padding) between a word “Admin” near No. 3 (written in Cyrillics) - just above the photo AND also where topic name appears in an upper post’s section (near No. 1) .
I want to make that space WIDER (as you can see in the picture where I used arrows to simplify the explanation).

You lost me a bit with your explanation but if you just want more space at the top of those 2 light blue coloured blocks then add some top padding as follows:


.poster,.postarea {padding-top: 5px;}

Thanks a lot!
That’s exactly what I needed!
Have a great day!
Bye!
P.S. I’ve added an additional line. This one:
.poster,.postarea {padding-bottom: 12px;}
Just for the sake of proportions…
