Hi Joseph. You're welcome and thank you.
To change the hover of "...log yourself in", you would have to drop this into your stylesheet.css;
Code:
.greeting a:hover { color: #000000 }
The hex value is black, but you can change the hover color to what you wish or let me know if you want a specific color to decode for you or just wait until I post an updated one with your color choice before adding the above.
If I understand, you would like some whitespace under your copyright?
You can drop this into your stylesheet;
Code:
#siteinfoLegal { padding-bottom: 10px }
You can adjust the value in red to your liking, also you can omit "-bottom" so there is also an equal amount of padding top/bottom of the copyright.
The space below the header as you mentioned, is taken up by an optional category bar. You can't see the displayed category link because the text is white upon a white background. Do you want to turn them off? That way, it will let the air out of that area. It's a simple switch in the Admin. Go into Admin-Configuration-Layout Settings;
`Categories-Tabs Menu ON/OFF = 0(off)
However, there will be a little bit of space left to trim off... but, we'll get there when these original queries are taken care of to your satisfaction.
