Hi, @hi.cinta,
when you successfully install and activate your child theme, you need to add into file style.css (Use Appearance -> Editor for this):

a {
color:#any_color_you_want;
}
.breadcrumb {
border-top:#any_color_you_want;
}

Note: This code will work only if you add it into style.css in your activated child theme.
One more note: If you use child theme example from this topic you need to delete from this example folder post-formats.

@insite.ryan,
please, try to add several posts for testing (upload new featured images, not select from earlier uploaded images)

Hi,
Slider shows featured images from blog posts. So you need set up featured image for your post and it will be shown in slider

Hmm… Are you sure that doing all right? I watch on your slider with Firebug in Mozilla and can’t find this code.

First off all I recommend you to create your own child theme for Duena (for safety editing template files, you can find tutorial here – http://codex.wordpress.org/Child_Themes).

Then, if you need centered content only on single post page – copy into your child theme file single.php, open it in editor and find string <div id="primary" class="span8 <?php echo esc_attr( of_get_option('blog_sidebar_pos') ) ?>">. Then change it to
<div id="primary" class="span12 <?php echo esc_attr( of_get_option('blog_sidebar_pos') ) ?>">
If you need all pages with center content – find all files wich contains this string and replace it with <div id="primary" class="span12 <?php echo esc_attr( of_get_option('blog_sidebar_pos') ) ?>">

But it’s not good idea, because a lot of styles in theme adapted to two columns structure and some elements after that manipulations can look not good

Hi
First, before making any changes, be sure to create and activate a child theme for Duena. The WordPress Codex has a great tutorial: http://codex.wordpress.org/Child_Themes.

Then go to Apperance -> Editor and add next code to style.css:

.post_type_label,
.post_date {
  display:none;
}

This could occur when you unpacked the archive. Structure of child theme must be – duena_child-master/style.css for correct work
