This chapter will discuss about Bootstrap spinners. Bootstrap spinner display the loading state of projects using .spinner class.
How it works
-
Bootstrap spinners show the loading state of a project, using HTML and CSS. JavaScript is not required to build them.
-
Custom JavaScript is needed to toggle their visibility. Appearance, alignment, and sizing can be easily customized with Bootstrap”s utility classes.
- Each loader has role=”status” and a nested <span class=”visually-hidden”>Loading… </span > for accessibility.
Border spinner
Use .spinner-border class to create lightweight spinner/loading indicator.

<span class="visually-hidden"></span>
</div>
<div class="spinner-border text-secondary" role="status">

</div>
<div class="spinner-border text-success" role="status">
<span class="visually-hidden"></span>
</div>
<div class="spinner-border text-danger" role="status">
<span class="visually-hidden"></span>

<span class="visually-hidden"></span>
</div>
<div class="spinner-border text-dark" role="status">
