W3Schools is a pretty good place to start getting familiar with CSS. See this entry on margins. And all style rules are located in the style sheet, style.css, which you can edit in Appearance=>Editor however I highly recommend using an FTP client and a dedicated code editor. A code editor offeres many essential features missing from WP’s editor such as syntax and error highlighting and the ability to revert through your changes in case you make any mistakes.
The title styles are set in this rule in your style sheet
#title {
font-family: ‘Play’, arial, serif;
font-size: 48px;
font-weight: bold;
line-height: 48px;
margin: 0;
text-shadow: 2px 2px #000;
text-transform: uppercase;
}
And you can activate the secondary navbar in the Genesis Theme Settings panel.
