reducing spacing on home page

I went into the style.css file and may have deleted something by accident.
Im using the Metric child theme.

Thanks.

As the parent theme is a commercial product, you need to seek support from the theme’s vendors.

I’m using the child theme for style changes.

Can’t I resolve this by finding the problem in the style sheet?

It costs $$ to post and ask questions on studiopress.com’s forums page.

We do NOT support premium themes as you paid for support when you bought the theme. It is not our place to keep theme vendors in business or deprive them of any income that they may derive from support services.

I’m just asking for some help with my website here; most people are happy to give advice on coding changes and which files to access, etc.
