Example

{% block body %}
    <div class="{{ bemBlock('listing') }}">
        <div class="{{ bemElem('pagination') }}"></div>
        <div class="{{ bemBlock('product') }}">
            <div class="{{ bemElem('title') }}"></div>
        </div>
        <div class="{{ bemBlock('product', ['active', 'sale']) }}">
            <div class="{{ bemElem('title', ['bold']) }}"></div>
        </div>
    </div>
{% endblock %}

<div class="listing">
    <div class="listing__pagination"></div>
    <div class="product">
        <div class="product__title"></div>
    </div>
    <div class="product product--active product--sale">
        <div class="product__title product__title--bold"></div>
    </div>
</div>
