Навигация по сайту осуществляется с помощью типового XSL шаблона, не имеющего стилей внутри себя:

/* ХЛЕБНЫЕ КРОШКИ  */ 
.navigation { 
   font-family: Arial, Helvetica, sans-serif; 
   font-size: 100%; 
   margin: 20px 0 20px 0; 
   padding-left: 1%; 
   font-weight: normal; 
   color: #6c7b3d; 
} 
 
.navigation a { 
   font-family: Arial, Helvetica, sans-serif; 
   font-size: 100%; 
   color: #6c7b3d; 
} 

<div class="navigation"> 
<?php 
// Вывод строки навигации 
$Structure_Controller_Breadcrumbs = new Structure_Controller_Breadcrumbs( 
        Core_Entity::factory('Site', CURRENT_SITE) 
    ); 
$Structure_Controller_Breadcrumbs 
    ->xsl( 
        Core_Entity::factory('Xsl')->getByName('ХлебныеКрошки') 
    ) 
    ->show(); 
?> 
</div> 

А получается, что название открытой страницы подпрыгивает вверх (скриншот).

Как можно предположить, причина в каких-то наложенных стилях, то есть в их наследовании.

Чтобы попытаться это увидеть, в Хроме жму Ф12 и получаю в правой части экрана список, в котором ничего невозможно понять...

Что здесь создает проблему?
