super-modal

A versatile, CSS-only, scrollable modal that shrink wraps its content. You must define your own styles for now.

Requirements

• Tailwind

Elements

• -outer - The outermost container of all modal pieces
• -overlay - The darkened background
• -inner - The centred area that holds the content
• -closeButton - The close button

Attributes

• modifierClassName - (Optional) Class name to add to the modal to differentiate between modals for styling purposes
• outerClassNames - (Optional) Class names to add to the -outer div
• overlayClassNames - (Optional) Class names to add to the -overlay div
• innerClassNames - (Optional) Class names to add to the -inner div
• closeButtonClassNames - (Optional) Class names to add to the close button button
• disableOverlayClose - (Optional) Remove the ability to click on the overlay to close the modal

NOTES:

Because the SuperModal shrink wraps its content (i.e., the -inner div contracts to fit the content inside of it), its behaviour can depend on the type of content that it holds.

If the content has a set width or max-width, no problem, the -inner div will shrink to fit it. But if the content doesn't have a fixed width - like a bunch of 100% wide paragaphs for example - you must supply a max-width for the -inner div so that the modal doesn't fill the full width of the window. You can do this in a few different ways:

• By passing in a max width utility class into the innerClassNames attribute
• Adding a max-width property to a custom SuperModal-inner CSS rule.
• Wrapping the content in a div and adding a max-width to that

Inversely, it can happen that the -inner div shrink wraps the content a little too much and the modal becomes too narrow. If this happens, add a width: 100%; max-width: Xrem (where Xrem is the desired width of the modal) to your -inner custom CSS rule, or pass equivalent utility classes into the innerClassNames attribute.

Example CSS

Copy this CSS to lay the foundation for your modal.
