Creating Archive Template Using Layout Shortcode?

I’m using beaver themer to create custom post archive layout. I want to use a custom post list and modify the layout. The question I have is: What classes should I use to create divs that would arrange in a grid layout? Does beaver builder provide a grid system like that? Or is it better just to write more own CSS? I don’t want to create more work than I have to. =)

Each post would have the following markup

<div class="row">
    <div class="author-img">post_img</div>
    <div class="author-bio">author_bio</div>        

I think I answered my own question. If you’re using the beaver theme you can use bootstrap 3 or 4.
