Gap above logo?

I put a sample logo in the logo module in my Joomla site based on your template.

However, there is a big gap above the logo. I couldn't figure out a way of moving the logo up, as it doesn't seem that it can be adjusted in the logo module.
Where should I look to adjust this?
I am familiar with HTML and CSS, I just don't know where to change it.

Thank you much.

Hi,

in layout.css

.logo_pad {
padding-top: 50px;
}

when you remove that maybe you will need to add something like
margin-top: -10px;

BTW. If you are familiar with HTML and CSS don't miss Chrome browser debugger you start with Inspect Element option. Using it you can check and test all live.

Thank you much. I'll give that a try. Will go hunt down layout.css.
