Bueno Theme Customization Help Needed

.sd-title, .post-meta li .head {
color: blue;
}

OH and the submit button

#commentform #submit {
background-color: red;
}

I must be tired, responses & related.

#main h3 {
color: pink;
}

This worked perfectly! Thank you so much for your help! Do you happen to know how I could widen my content area and side bar to reduce the white space on both sides? I have tried code in the past that did this, but then when I viewed the page on a standard (non-wide screen) monitor, it chopped off the edges of the content and sidebar and did not provide me a scroll bar.

Also, I would like the line beneath each comment to go away. I would appreciate any advice on clearing that divider line.

#comments .comment .comment-container {
    border-bottom: 0;
}

Do you happen to know how I could widen my content area and side bar to reduce the white space on both sides?

You can try this, other than 1 image everything seemed to work on non-widescreen resolutions I tried.

#header {
    width: 100%;
    margin: 0 auto;
    text-align: center;
}
#logo {
    float: none;
}
#content {
    width: 85%;
    margin: 0 auto;
}
#main {
    width: 60%;
}
#sidebar {
    width: 35%;
}

#subscribe-blog-blog_subscription-2 {
    margin-left: 15px;
}

Thank you so much for all of your help batharoy! You have helped me tremendously!
