widget area not showing

1. Make sure you place widgets in the Main sidebar area, not the Right one. Right is used for the Left and Right sidebar template.

2. Buttons:

#content input[type="submit"], #content input[type="reset"], #container #searchsubmit, .button, #new-topic {
  background: #000;
  border: 0 none;
  box-shadow: none;
  color: #ccc;
}

Form field borders:

#container input, #container textarea {
  border: 1px solid #666;
}

3. You can adjust by adding:

body.custom-background {
  background-position: center 100px;
}

Then change up 100px as needed.
