Modal Component

A lightweight, accessible modal dialog component built with native HTML dialog elements and Tailwind CSS. Display overlays for confirmations, forms, and detailed content without heavy JavaScript. Supports multiple sizes, custom headers, footers, and focus-trap behavior.

Modal components display important information or request user action in a focused, overlay window. Built on semantic HTML dialog elements, modals support animations, customizable positioning, and backdrop overlays. The Frutjam modal system is fully accessible with keyboard navigation and trap focus, making it ideal for confirmations, forms, and alert dialogs.

Modal placements

The modal component is by default positioned in the center of the screen, but it can be placed depending upon the use case using horizontal classes modal-start, modal-center, or modal-end, and vertical classes modal-top, modal-middle, or modal-bottom. Placement is designed with RTL and LTR compatibility in mind, making the modal adaptable to different language directions and layouts.

Use modal-start, modal-center, or modal-end for horizontal placement and modal-top, modal-middle, or modal-bottom for vertical placement. These classes are applied to the modal component.

Responsive positioning of modal for desktop and mobile screens

Depending on your use case, you can position the modal anywhere on desktop or mobile—for example, desktop center and mobile top center.

Responsive modal

Resize the modal to a small screen to see the change in modal position.

Modal positioning based on language direction

Place the modal wherever on the screen depending on the language direction (LTR or RTL).

Right-aligned and vertically centered in LTR and RTL

Responsive modal

Changing dir="rtl" in the HTML will have no effect on the modal's the position because the layout is controlled by utility classes: modal-end for the LTR variant and modal-start for the RTL variant.
