Total newbie, so sorry if this is easy.

I purchased a new skin, installed etc.  My issue is that the logo is not fitting right/perfect.  There is a white line to the left of the logo that I can't seem to get rid of.  I've done a lot of searches, and I've read through the various .ascx files, and I'm not getting it.  (I'm not a developer in any way)

Also, the font size on my site is very aggravating.  It's either too small or too big in all my modules.  I use the built in rich text editor and when I select font size 3, it's too small.  Font size 4 looks too big.  I just want a happy medium.

site is www.cagleads.com

I would appreciate any help you can provide.  Keep in mind, I am totally new to all of this.  (css or ascx mean nothing to me)

actually I may need some help for that problem :)

please look at the top logo.  No  matter how I change size of the title logo it just won't fit, and always have the white boarders.

Thanks Timo for helping me out, both this problem and the content pane sizing problem.

I went to   \portals\_default\skins\dnn-blue  folder
there is only one css file which is skin.css file.  I ftp that to my local drive and try to edit it.
but the syntax are different
for instance rather than
#dnn_ContentPane
I see
.contentpane {
    width: 400px;
}
also I cannot file the <table class =...> tag, or any html tag anywhere in the file.
Am i in the wrong place?
