Heading

The heading level, 1 to 6, which sets the element (h1 to h6). Defaults to 2.

Lists the heading in the page's OnThisPage (when its level is one it lists). Defaults to true; false leaves it out and gives it no anchor link.

Makes the heading a link to itself, with a "#" on hover, so a section can be linked. By default, headings listed in an OnThisPage are; true adds the link to any heading with an id, false removes it. A heading whose content holds a link or button of its own (an a, button, Anchor or button component) never gets one, since links can't nest. A heading holding a component that isn't one of IzzyBlazor's plain ones (Icon, Badge, Kbd, TextBlock) gets one only with true, since it might render a link. Set it as Anchor="true": the attribute needs a value.

Font size. Responsive.

Font weight.

Horizontal alignment. Responsive.

Line height.

Letter spacing.

Letter case.

Underline or strike-through.

Italic.

How lines break: normal, never, balanced or pretty.

Keep to one line and end with an ellipsis when it does not fit.

Show at most this many lines, ending with an ellipsis.

Equal-width digits, so numbers line up in columns and do not jitter when they change.

Makes the size fluid: the text is MinSize on a 360px screen and grows smoothly to Size at 1280px and up, as for a hero heading: <Heading Size="TextSize.Xl5" MinSize="TextSize.Xl3">. Replaces per-breakpoint sizes: with them, it grows to the size for the widest breakpoint given.

The content.

Margin on all sides, in spacing steps (-16 to 16; one step = 4px).

Horizontal margin. When set, replaces Margin on this axis.

Vertical margin. When set, replaces Margin on this axis.

Top margin. When set, replaces MarginY and Margin on this side.

Bottom margin. When set, replaces MarginY and Margin on this side.

Margin at the start (left in left-to-right text, right in right-to-left). Replaces MarginX and Margin on this side.

Margin at the end (right in left-to-right text, left in right-to-left). Replaces MarginX and Margin on this side.

Width.

Minimum width.

Maximum width.

Whether to grow into free space inside a Stack, Row or Column: <Box Grow>.

Whether to shrink when space is short inside a Stack, Row or Column. Defaults to true; Shrink="false" keeps the size.

Starting size inside a Stack, before growing or shrinking.

Alignment across the parent's direction, overriding the parent's Align for this component only, such as a button lined up with the bottom of labeled fields in a Row.

How many columns it spans in a Form or Fieldset with Columns, or a Grid; GridSpan.Full for the whole row. Never more than the columns shown, so a form that narrows to one column needs no breakpoints.

Starts a new row in a Form or Fieldset with Columns, or a Grid, leaving the rest of the row before it empty.

The color scheme inside: ColorScheme.Dark for a dark band on a light page, ColorScheme.Inverse for the opposite of the page. It also sets the surface background and text color, which Bg and Color override.

Padding on all sides, in spacing steps (0 to 16; one step = 4px).

Horizontal padding. When set, replaces Padding on this axis.

Vertical padding. When set, replaces Padding on this axis.

Top padding. When set, replaces PaddingY and Padding on this side.

Bottom padding. When set, replaces PaddingY and Padding on this side.

Padding at the start (left in left-to-right text, right in right-to-left). Replaces PaddingX and Padding on this side.

Padding at the end (right in left-to-right text, left in right-to-left). Replaces PaddingX and Padding on this side.

Background color.

Text color. When not set and Bg is a theme color, the matching contrast color is used automatically (Bg="Color.Primary" gets Color.OnPrimary text).

Corner radius.

Elevation.

Minimum height.

Height.

Maximum height; pair it with Overflow to scroll what doesn't fit.

What happens to content that doesn't fit: Overflow.Auto to scroll it.

A border on every side, in whole pixels (0 to 16), in BorderColor (the border token by default) and BorderStyle (solid by default). Like padding: BorderX and BorderY override an axis, the single sides override that. Sides you don't set keep the component's own border.

Borders at the start and end. Replaces Border on this axis.

Borders at the top and bottom, such as a band with lines above and below. Replaces Border on this axis.

The top border. Replaces BorderY and Border on this side.

The bottom border. Replaces BorderY and Border on this side.

The border at the start (left in left-to-right text). Replaces BorderX and Border on this side.

The border at the end (right in left-to-right text). Replaces BorderX and Border on this side.

The border color, for borders set here or the component's own. Defaults to Border.

How borders set here are drawn (BorderStyle.Dashed, BorderStyle.Dotted), and the own border of a Card or a bordered EmptyState. Solid by default (dashed on an EmptyState).

Extra CSS classes, merged after the component's own classes.

Inline style, appended after the component's generated custom properties.

Hides the component from this breakpoint up, such as a menu button only phones need.

Shows the component only from this breakpoint up, such as header links for wide screens.
