Class lacking any discernible design elements on a Bootstrap webpage

I am currently customizing a Bootstrap template and delving into its code to gain a deeper understanding. I believe it's beneficial for me to explore the code so that I can enhance my skills in creating similar websites independently. If you're curious, you can view the template through this link: Dance Whirl

Upon examining the website, I noticed various classes and ID's that appear to be unused in both the CSS and JS files. The template comprises 7 CSS files and 12 JS files. To further investigate, I documented all classes and IDs present in the HTML code and cross-referenced them with the associated files. Surprisingly, I discovered that several were not utilized in any of the files.

My main query revolves around the "slider" class. This particular div houses other elements forming a carousel and banner image display. Despite an extensive search across different files, including the core bootstrap files, no references to the "slider" class were found. I even conducted online searches using variations like class="slider", bootstrap slider, and bootstrap class="slider," yet couldn't find any indications that it is related to Bootstrap.

Am I overlooking something crucial? Is "slider" actually a specialized Bootstrap class? If not, what could be the purpose behind incorporating a class without any specific styles within a div?

Below is a snippet of the concerning code:

    <!-- banner-text -->
    <div class="slider">
        <div class="callbacks_container">
            <ul class="rslides callbacks callbacks1" id="slider4">
                <li>
                    <div class="w3layouts-banner-top">
                        <div class="container">
                            <div class="agileits-banner-info">
                                <h3>Shall We <span>Dance</span> ?</h3>
                                    <p>CELEBRATE YOUR EVENT WITH US</p>
                                <div class="agileits_w3layouts_more menu__item">
            <a href="#" class="menu__link" data-toggle="modal" data-target="#myModal">Learn More</a>
        </div>
                            </div>  
                        </div>
                    </div>`

Answer №1

Don't stress over it; the class isn't part of the official Bootstrap library. It's common for people to add classes for clarity in markup or thinking they'll need to style an element when in fact they won't.
