Sass: Is it possible to add a class using Sass to an HTML-Element afterwards?

Viewed 23381

I hope somebody can help me with my question.

Lets say I have this:

            <div class="container">
                <div class="row">
                    <article>
                        <p class="story-image">
                            <a href="#">
                                <img src="../media/images/awesomeness.jpg" alt="image1" class="img-responsive">
                            </a>
                        </p>
                        <section>
                            <h3>Companies</h3>
                            <h2>
                                <a href="#">
                                    Awesome-O beherrscht die Welt
                                </a>
                            </h2>
                            <p>
                                Last year, was pretty medium. But I know, by the power of my thought and my willpower, that I will make two companies and earn millions.
                            </p>
                        </section>
                    </article>
                </div>
           </div>

So, when using Twitter Bootstrap, I can apply the grid system to my HTML. Is it possible by using sass to apply a class to the article, even if it wasn't applied in the HTML from the beginning?

for example somehow like this:

 html{
      body {
           article {
                addclass --> col-lg-4 col-md-4 col-sm-6 col-xs-12;
           }
      }
 }

The reason I want to do it afterwards with sass, is that I have a bunch of articles, And I have to apply the grid system on them. But I am sure that I am going to revealuate at a later point the actual width and the ammount of the columns.

Is this possible with Sass and if yes, how?
