Growing Spinner Properties

Name	Description
ID	Sets this element’s unique page identifier. Use a stable name such as projectSummary when another control, label or anchor must target it. Do not duplicate a static ID inside repeated markup; a component binding name and a form field’s submitted Name serve different purposes.
Class	Edits the element’s space-separated CSS class list. For example, add a project-defined class such as project-summary only when your stylesheet defines it. Preserve classes required by the component. A class name alone does not create CSS, load an extension or implement an event handler.
Color	Options: Primary (text-primary), Primary Emphasis (text-primary-emphasis), Secondary (text-secondary), Secondary Emphasis (text-secondary-emphasis), Success (text-success), Success Emphasis (text-success-emphasis), Danger (text-danger), Danger Emphasis (text-danger-emphasis), Warning (text-warning), Warning Emphasis (text-warning-emphasis), Info (text-info), Info Emphasis (text-info-emphasis), Light (text-light), Light Emphasis (text-light-emphasis), Dark (text-dark), Dark Emphasis (text-dark-emphasis), Body (text-body), Body Emphasis (text-body-emphasis), Body Secondary (text-body-secondary), Body Tertiary (text-body-tertiary), Black (text-black), White (text-white), Black 50 (text-black-50), White 50 (text-white-50), Muted (deprecated) (text-muted) Default: "".
Type	Spinner style. Chooses the spinner style. Depending on the rule, this switches between border and grow spinners ( spinner-border vs spinner-grow ). Bootstrap docs: Spinners Options: Default, Small (spinner-grow-sm) Default: "".

Spacing

Name	Description
Margin and Padding	Sets outer margin and inner padding utilities for the selected viewport breakpoint. For example, at MD, bottom margin 3 becomes mb-md-3; without a breakpoint, p-3 adds padding on every side. Start/End follow writing direction. The spacing scale comes from the project theme. Negative margin classes require a stylesheet built with negative-margin utilities enabled; the bundled default disables them. Options: mt-0, mt-1, mt-2, mt-3, mt-4, mt-5, mt-n1, mt-n2, mt-n3, mt-n4, mt-n5, mt-auto, mb-0, mb-1, mb-2, mb-3, mb-4, mb-5, mb-n1, mb-n2, mb-n3, mb-n4, mb-n5, mb-auto, ms-0, ms-1, ms-2, ms-3, ms-4, ms-5, ms-n1, ms-n2, ms-n3, ms-n4, ms-n5, ms-auto, me-0, me-1, me-2, me-3, me-4, me-5, me-n1, me-n2, me-n3, me-n4, me-n5, me-auto, mx-0, mx-1, mx-2, mx-3, mx-4, mx-5, mx-n1, mx-n2, mx-n3, mx-n4, mx-n5, mx-auto, my-0, my-1, my-2, my-3, my-4, my-5, my-n1, my-n2, my-n3, my-n4, my-n5, my-auto, m-0, m-1, m-2, m-3, m-4, m-5, m-n1, m-n2, m-n3, m-n4, m-n5, m-auto, pt-0, pt-1, pt-2, pt-3, pt-4, pt-5, pb-0, pb-1, pb-2, pb-3, pb-4, pb-5, ps-0, ps-1, ps-2, ps-3, ps-4, ps-5, pe-0, pe-1, pe-2, pe-3, pe-4, pe-5, px-0, px-1, px-2, px-3, px-4, px-5, py-0, py-1, py-2, py-3, py-4, py-5, p-0, p-1, p-2, p-3, p-4, p-5.
X Gutter	Sets the horizontal Bootstrap row gutter through a gx-* utility. For example, gx-3 changes the spacing between columns when applied to a Bootstrap row. It works through the row and column gutter rules; adding it to an unrelated element does not create a column layout. Options: 0 (gx-0), 1 (gx-1), 2 (gx-2), 3 (gx-3), 4 (gx-4), 5 (gx-5). Default: no override from this control.
Y Gutter	Sets the vertical Bootstrap row gutter through a gy-* utility. For example, gy-3 adds space between wrapped rows of columns. It does not replace padding inside a card or change the spacing of a non-grid element by itself. Options: 0 (gy-0), 1 (gy-1), 2 (gy-2), 3 (gy-3), 4 (gy-4), 5 (gy-5). Default: no override from this control.

Display

Name	Description
Hide on	Hides the element at selected viewport ranges by adding responsive display utilities. For example, hiding below MD produces d-none with a restoring display class at MD. The control uses the component’s normal display type when restoring it. This hides layout and content visually; it does not protect private data or stop a server endpoint being called. Options: Hide on mobile (xs), Hide on landscape mobile (sm), Hide on tablet (md), Hide on laptop (lg), Hide on desktop (xl), Hide on extra wide (xxl).
Print	Controls whether this element appears in printed output. Hide writes d-print-none. Show restores the component’s display type for print, such as d-print-block or d-print-table-row. For example, hide a navigation bar when printing a report. Check browser print preview because screen layout alone does not show this setting. Options: Show (d-print-block), Hide (d-print-none).
Visually Hidden	Adds visually-hidden: content remains available to assistive technologies while it is visually clipped. Use it for an accessible label that should not appear on screen, not for hiding private data. It is different from display:none, which also removes the element from layout and generally from the accessibility tree. Default: off.
Focusable	Adds visually-hidden-focusable, which hides the element until it or a descendant receives focus. A skip link is a typical example. The element must already be focusable, such as an anchor with href; this class does not add keyboard focusability. Do not combine it with an unconditional visually-hidden class, which would keep it hidden even when focused. Default: off.
