Parameters:

• blockName: String
• modifiers: (optional) String[]

bemElem(elementName, modifiers = [])

This function can only be used if there is a bemBlock defined in the parent tree. Use it like this: <div class="{{ bemElem('myElement') }}"></div>

• modifiers: (optional) String[]

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 %}

This will be the corresponding output/markup:

<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>
