Thank you

For right and left sidebars

.tc-sidebar .widget {
    border: 1px solid #999999;
    margin: 0 0 18px;
}

Ah, .tc-sidebar ?? Thanks you!!!!

Another question.
Maybe you can help me quick. i wanna get rid auf the Word ?Beitragsnavigation” or ?Post navigation” after the posts. Just the Word, not the navigation. Can you help me with this?

In your child-theme functions.php:

add_filter('tc_list_nav_title', '__return_empty_string');
add_filter('tc_post_nav_title', '__return_empty_string');

Hope this helps.

Your are great, thank you. Have a nice day!

You too!
