How to correctly formulate classes according to bam?

Question

css

Good afternoon, tell me please, if for example I have such a block, can I arrange the classes like this, and specifically the modifiers?

<section class="scroller">
        <div class="text-block scroller__text-block">
            <h1 class="text-block__h text-block__h_scroller">WE ARE CODE CAFE</h1>
            <p class="text-block__p text-block__p_scroller">sfdsgsdgdfhgfhgfhfghgfhf</p>
        </div>
</section>

in classes with the _scroller modifier, I also set the positioning of h1 and p because when I use the text_block class in other sections, their positioning relative to each other will be different. Are such modifiers bad form or is it normal?
