[Решено] apply different font for new language

Background of the issue:
Original language of my site is Japanese. With WPML, I'm trying to create the pages in English (скрытая ссылка). In English pages, I would like to apply a different font family and added the following code in CSS: html[lang="en"] h1, html[lang="en"] h2 { font-family: 'Open Sans Condensed', sans-serif !important; }

Symptoms:
The CSS is not working because even in the translated page (скрытая ссылка), the language setting of the HTML remains .

Questions:
How can I change the HTML language setting to for English pages?
How can I apply a different font for each language using WPML?
