Decrease spacing on the right

Sorry guys, I'm not very adapt to CSS. Couldn't find where to do decrease spacing on right and increase the content area width.

Please help me out. Thanks !

I think this is where you want to update that:

article h1, article h2, article h3, article h4, article h5, article h6, article p, article blockquote {
    max-width: XXXpx; <-- Set this to your desired width
    padding-right: 100px;
}

Doesn't work awelle. I would like to add one more thing that I want to do this for a page content, not a post.
