IE7 css ul li rendering issue

Question

I have wierd CSS displaying problem with IE7 and IE6.

http://www.photopoint.ee there are three UL LI list-menus which doesn't have CSS style in IE7.

With IE8, Chrome, FF, Opera everything works as expected.

I validated CSS and HTML with w3.org validator, there were no "critical errors" which could be the source of the problem.

I'm out of thoughts what could be the problem.

Answer 1

Issue fixed:

Following CSS lines broke the layout:

#tekstiosa ol li { counter-increment: section; line-height: 18px;}
#tekstiosa ol li:before { content: counters(section, ".") ". "; }
