About
Bootstrap "spinners" can be used to show the loading state in your projects. They're built only with HTML and CSS, meaning you don't need any JavaScript to create them. You will, however, need some custom JavaScript to toggle their visibility. Their appearance, alignment, and sizing can be easily customized with our amazing utility classes.
For accessibility purposes, each loader here includes role="status" and a nested <span class="sr-only">Loading...</span>.
Border spinner
Use the border spinners for a lightweight loading indicator.
{% capture example %}
Colors
The border spinner uses currentColor for its border-color, meaning you can customize the color with [text color utilities][color]. You can use any of our text color utilities on the standard spinner.
{% capture example %} {% for color in site.data.theme-colors %}
{% capture callout %}
Why not use border-color utilities? Each border spinner specifies a transparent border for at least one side, so .border-{color} utilities would override that.
{% endcapture %}
{% include callout.html content=callout type="info" %}
Growing spinner
If you don't fancy a border spinner, switch to the grow spinner. While it doesn't technically spin, it does repeatedly grow!
{% capture example %}
Once again, this spinner is built with currentColor, so you can easily change its appearance with [text color utilities][color]. Here it is in blue, along with the supported variants.
{% capture example %} {% for color in site.data.theme-colors %}
Alignment
Spinners in Bootstrap are built with rems, currentColor, and display: inline-flex. This means they can easily be resized, recolored, and quickly aligned.
Margin
Use [margin utilities][margin] like .m-5 for easy spacing.
{% capture example %}
Placement
Use [flexbox utilities][flex], [float utilities][float], or [text alignment][text] utilities to place spinners exactly where you need them in any situation.
Flex

{% capture example %}
Floats
{% capture example %}
Text align
{% capture example %}
Size
Add .spinner-border-sm and .spinner-grow-sm to make a smaller spinner that can quickly be used within other components.
{% capture example %}
Or, use custom CSS or inline styles to change the dimensions as needed.
{% capture example %}
Buttons
Use spinners within buttons to indicate an action is currently processing or taking place. You may also swap the text out of the spinner element and utilize button text as needed.
{% capture example %} Loading... Loading... {% endcapture %} {% include example.html content=example %}
{% capture example %} Loading... Loading... {% endcapture %} {% include example.html content=example %}
