Thanks everyone, now errors are 6 so at least there is some progress: http://validator.w3.org/check?uri=http%3A%2F%2Fklikerlab.pl%2F&charset=%28detect+automatically%29&doctype=Inline&group=0
I found where are the "p" tags ("**end tag for element "p" which is not open"). In page source it looks like this: <p class="malytyt"> <a href="http://klikerlab.pl/2009/12/13/targetowanie-i-kilka-nowosci/">Targetowanie i kilka nowoĊci</a> </p> </p> So indeed, too many end tags... but the code that generates it, looks like this: <div id="sidebar" class="aside"> <?php query_posts('showposts=8&orderby=date'); ?> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <div class="navpudelko"> <p class="malytyt"><a href="<?php the_permalink() ?>"><?php the_title() ?></a></p> <?php $excerpt = strip_tags(the_advanced_excerpt('length=20&no_custom=1')); echo $excerpt; ?> <!--end navpudelko--></div> <?php endwhile; endif; ?> <!--END #secondary .aside--> </div> and here "p" tags look ok... so I don't know what to change. As for divs, I tried adding or removing them but it just created more errors. Still the excerpt titles are blue in Firefox, while I wanted them to be brown like in Safari ;) and the shadow around two banners looks too large in Firefox. And I can't find newer archives from css-d, here the latest is from September: http://archivist.incutio.com/viewlist/css-discuss/ Thanks again!
