Display a grey header over inset?

Hi, www.neue.antiquariatszeitung.de , (how) can I display a grey header with headerline over the inset/middle part of the site, like the module-headers have?

In template_css.php

replicate styles for

div.moduletable h3

for

.items-row .item h2

Hi, sorry Ivan; dind't grap your information. Found div.moduletable h3, but there is a whole bunch of code behind it. What should I replicate?

add

.items-row .item h2 h3 span {
color:<?php echo $columnFirstWord; ?>;
}

.items-row .item h2 h3 {
color:<?php echo $columnHeading; ?>;
background: -webkit-gradient(linear, 0 0, 0 bottom, from(<?php echo $modulesHeadingBgStart; ?>), to(<?php echo $modulesHeadingBgEnd; ?>));
background: -moz-linear-gradient(<?php echo $modulesHeadingBgStart; ?>, <?php echo $modulesHeadingBgEnd; ?>);
background: linear-gradient(<?php echo $modulesHeadingBgStart; ?>, <?php echo $modulesHeadingBgEnd; ?>);
-pie-background: linear-gradient(<?php echo $modulesHeadingBgStart; ?>, <?php echo $modulesHeadingBgEnd; ?>);
filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0,startColorstr='<?php echo $modulesHeadingBgStart; ?>', endColorstr='<?php echo $modulesHeadingBgEnd; ?>');
position:relative;
}

to template_css.php, and

.items-row .item h2 h3 {
font-size:17px;
font-weight:normal;
font-family:"Lucida Sans Unicode", "Lucida Grande", sans-serif;
text-transform:uppercase;
margin:0 0 7px 0;
padding:0 0 0 25px;
line-height:35px;
}

to template_css.css

Hi, this didn't work or I did it wrong. It had no effects on the displaying a header over the main/middel part of inset. I will try it later once again.

my mistake , it's:
add
to template_css.php, and
to template_css.css
