Customizing mediaquery styling in Bootstrap

Below is the example code showcasing #data in either md-12 or sm-6 depending on browser width. Under certain conditions (such as a special preview mode triggered by JavaScript), I wish to override the rendering rules for #data and display only in col-md-12 even on small screens.

I prefer not to remove any classes from the DOM, but instead seek a solution using .parent (where I can add a class) to overwrite its child's rendering rules.

In essence, I aim to compel Bootstrap to display content in md mode while disregarding browser width.

I am also curious if adjusting the viewport value could resolve this issue?

<div class="parent">
    <div class="row">
        <div id="data" class="col-md-12 col-sm-6">data</div>
    </div>
</div>

Answer №1

How can the element recognize when it is in a unique state?

Is there a method to dynamically apply a class to the .parent element (such as .preview) or any of its ancestors?
If this is the case, one potential resolution may involve specifying a CSS rule with greater specificity like .preview #data, where you define the styles similar to those found in .col-md-12 (or specifically for properties that need to be reverted).

Here are some potential examples:

/* media query for .col-sm-6 */
@media (min-width: 576px) { 

  /* if only overriding styles for the #data element */
  .preview #data {
    /* styles from .col-md-12 */
    -ms-flex: 0 0 100%;
    flex: 0 0 100%;
    max-width: 100%;
  }

  /* if needing to override all instances of .col-sm-6 within a .preview element */
  .preview .col-sm-6 {
    /* styles from .col-md-12 */
    -ms-flex: 0 0 100%;
    flex: 0 0 100%;
    max-width: 100%;
  }

}
