Tips for making a DIV span the entire width of a page when it is within a column with the Bootstrap class 'col-md-6'

I'm having a little trouble arranging divs next to each other on a page. Specifically, I want to ensure that if there is only one instance of the col-xs-12 col-md-6 div class on the page, it should take up the full width (100%) instead of just 50%. The HTML code is fixed as it is being generated by MVC. Is there a way to achieve this using CSS or JavaScript/jQuery? I attempted to use the following JavaScript snippet, but it didn't work as expected.

Below is an example of my HTML and CSS:

<div class="col-xs-12 col-md-6 textcontent">
   </div>

<div class="col-xs-12 col-md-6 service">
   </div>

<div class="col-xs-12 col-md-6 textcontent">
   </div>

CSS

.col-md-6{
width: 50%;
}

JavaScript

if ($('.col-xs-12.col-md-6').length == 1) {
    $('.col-xs-12.col-md-6').toggleClass(".col-xs-12.col-md-12")
    }

Answer №1

The foundation of the Bootstrap grid system lies in a 12 column structure. Simply utilizing col-12 allows a column to occupy the entire width of its container.

Give this a shot:

<div class="col-12 textcontent">
   </div>

<div class="col-12 service">
   </div>

<div class="col-12 textcontent">
   </div>

Check out the documentation on the grid system in Bootstrap, including breakpoints for adjusting column configurations based on device screen size.

It seems like you're currently locked into using Bootstrap, but this task could easily be accomplished with Flexbox instead. Looking at your specific question and the code you shared, the issue lies in how you're toggling the classes.

if ($('.col-xs-12.col-md-6').length == 1) {
    $('.col-xs-12.col-md-6').toggleClass("col-xs-12 col-md-12");
}

When adding class names, make sure not to include the period ("."). Also, ensure that the class names are separated by spaces, just like in the HTML. You were mistakenly trying to add the class as "col-xs-12.col-md-12" instead of "col-xs-12 col-md-12."

Considering you're using Bootstrap, you probably won't need to define the css for .col-md-6 since Bootstrap should already have that covered.

Answer №3

To properly adjust your JavaScript code, make sure to eliminate the class "col-md-6".

if ($('.col-xs-12.col-md-6').length == 1) {
  $('.col-xs-12.col-md-6').removeClass("col-md-6")
}

The .col-xs-12 is effective for all screen sizes from xs and up. However, the .col-md-6 overrides it for screen size md and up. To prevent this override, simply remove the class.
