Is it necessary to include IDs for columns within a row in Bootstrap 4?

Is it advisable to use IDs in bootstrap .col elements nested within a .row? I recall reading that columns should only be directly under a .row. For instance:

<div class="container">
    <div class="row">

       <div id="style1" class="col-12">
       </div>

       <div id="style2" class="col-12">
       </div>

    </div>
</div>

Alternatively, should I create separate div tags like this?

<div class="container">
    <div class="row">

       <div class="col-12">
            <div id="style1">
            </div>
       </div>

       <div class="col-12">
            <div id="style2">
            </div>
       </div>

    </div>
</div>

Answer №1

Why it's important: The choice between using an ID or a class for a particular element ultimately comes down to how you plan on utilizing the CSS styles associated with that selector. If you anticipate needing to apply the same styles to multiple elements, then a class is the way to go. However, if you only intend to use those specific styles once, or if you need to easily target that one element with JavaScript/jQuery, then an ID may be appropriate.
