I've tried several themes, but it seems like Oxwald is really designed just to have text at the top, rather than a logo... Because no matter what I try, the logo ends up being tiny (essentially you can only use the size of the text area for a logo). Right now I'm trying GrayScale, and the logo is shoved into a really tiny space, although I've tried editing the css to make the space larger.

This is the site:

www.bible-soft.com

You can see the part of the logo that fits into the space made available by the theme is really tiny, pretty much useless, in fact. This is the css I currently have inserted:

.ow_header .ow_logo h2{
    visibility:hidden
}
.ow_header .ow_logo{
    background-image: url(http://bible-soft.org/ow_userfiles/themes/theme_image_10.jpg);
    height:100px;
    width:400px;
    right:70px;
    bottom:50px;
}
.ow_header .ow_logo .ow_tagline
{
    visibility:hidden
}

This doesn't seem to change anything.

Any way to fix this?
