On my Themes Exhibition I have 3 own (still 3) themes and in XF-Blocks module's block found strange effect in theme DC-Sinchtastic (0DC-Sinchtastic on site in odrer to be "on top"), which I can't understand: text inside



shown with ordinary text size, not as h1, and with correct size x-large in all other themes...

No, I didn't redefine h1 in theme, class xf_block <...> (sifferent for diffeent blocks) also missing in all themes

Problem visible in real life on main page of site... Well, not a problem (I can always edit template and add own class..), but strange effect, which I want to grok

Is the element "a" defined in the css. And of course the class xf_block would need to be defined in the template.

And I assume the closing < /div> tag is not shown.

Yes, a defined somewhere-somehow... Why different themes shows different size?
They work in the same conditions (almost same...)
