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>
