Put the full-size image and its accessible title into the dialog, call showModal(), provide a visible Close button, support Escape, and return focus to the thumbnail when the viewer closes. Native modal behavior makes the rest of the document inert while the image is open, so you do not have to recreate that part of an overlay.
What you are building
This example creates a single-image lightbox that works with mouse, keyboard and touch. The thumbnail is a real button, not a clickable <div>. JavaScript remembers which button opened the viewer, copies that button’s full-size URL and description into the dialog, and restores focus after closing.
- Meaningful
alttext describes the image to someone who cannot see or load it. - Explicit
widthandheightlet the browser reserve the correct aspect ratio and reduce layout shift. loading="lazy"is useful for thumbnails that begin below the fold.srcsetandsizeslet the browser select an appropriate thumbnail file when several widths exist.

HTML markup
Each trigger stores the large image URL in data-full and its spoken description in data-alt. The dialog has a visible heading, an explicit close control and an image with intrinsic dimensions.

data-full="mountain-1600.jpg"

JavaScript lifecycle
const viewer = document.querySelector('#viewer');
const viewerTitle = document.querySelector('#viewer-title');
const viewerImage = document.querySelector('#viewer-image');
const closeButton = document.querySelector('#viewer-close');
let opener = null;
document.querySelectorAll('.thumb').forEach((button) => {
button.addEventListener('click', () => {
opener = button;
viewerTitle.textContent = button.dataset.alt || 'Image preview';
viewerImage.src = button.dataset.full;
viewerImage.alt = button.dataset.alt || '';
viewer.showModal();
closeButton.focus();
});
});
closeButton.addEventListener('click', () => viewer.close());
viewer.addEventListener('click', (event) => {
// Close when the user clicks the backdrop, not the image or controls.
if (event.target === viewer) viewer.close();
});
viewer.addEventListener('close', () => {
viewerImage.removeAttribute('src');
if (opener) opener.focus();
});showModal() places the dialog in the top layer and makes the rest of the same document inert. Calling close() fires the close event, where focus is returned to the invoking button. Native dialogs also provide Escape cancellation. Keeping the close button inside the dialog is still essential for touch users and people without a physical keyboard.

Turn it into a gallery
Repeat the button for every image and keep one shared dialog. Give every thumbnail a unique full-size URL and description. The script above already handles all buttons because it queries .thumb. For a large gallery, lazy-load images that are initially offscreen, but keep the first visible row eager so it appears immediately. Lazy loading is only a fetch hint; it does not make an oversized file efficient. Generate appropriately sized files and use srcset and sizes on each thumbnail.
Gallery example
<div class="gallery">
<button class="thumb" type="button" aria-label="Open coast at full size"
data-full="coast-1800.jpg" data-alt="Rocky coast under a cloudy sky">
<img src="coast-320.jpg" srcset="coast-640.jpg 2x"
width="320" height="213" loading="eager"
alt="Rocky coast under a cloudy sky">
</button>
<button class="thumb" type="button" aria-label="Open forest at full size"
data-full="forest-1800.jpg" data-alt="Sunlit forest path">
<img src="forest-320.jpg" srcset="forest-640.jpg 2x"
width="320" height="213" loading="eager"
alt="Sunlit forest path">
</button>
</div>Accessibility details that make the viewer usable
Labels and alternative text
The dialog needs an accessible name. A visible <h2> referenced by aria-labelledby supplies one, and the heading should change to match the selected image. The thumbnail’s alt text is the image’s textual replacement; do not use filenames such as IMG_4832.jpg. If an image is decorative, use an empty alt="" rather than inventing a description.
Focus and dismissal
Move focus into the dialog after opening, preferably to the Close button. Escape should dismiss the modal, and the visible Close button should do the same. On close, return focus to the exact thumbnail that opened it. This prevents keyboard and screen-reader users from losing their place.

Pointer and touch behavior
Use a sufficiently large button target and preserve the browser’s focus outline. The optional backdrop-click handler should test event.target === viewer; otherwise a click on the image could close the viewer unexpectedly. Do not rely on hover or a tiny “×” icon without an accessible name.

Responsive images and performance
- Set dimensions on every thumbnail and on the dialog image. If source images have different ratios, use their actual dimensions or wrap them in a box with a deliberate aspect ratio.
- Use modern formats where your asset pipeline supports them, but retain a working fallback.
- Keep thumbnails small; opening a large image on demand avoids downloading every full-size asset on page load.
- Use
loading="lazy"only for images likely to start offscreen. It should not delay the main image unnecessarily. - For very large photographs, constrain the dialog image with
max-widthandmax-heightso it fits the viewport without distorting it.
Native dialog versus a custom overlay
| Concern | Native <dialog> |
Custom overlay |
|---|---|---|
| Modal stacking and backdrop | showModal() supplies the top layer and ::backdrop. |
You must implement stacking, backdrop and scroll behavior. |
| Background interaction | The rest of the document becomes inert while modal. | You must disable interaction and usually manage aria-hidden carefully. |
| Escape and close events | Native cancel/close lifecycle is available. | You must add keyboard listeners and cleanup. |
| Image features | You add your own zoom, pan, next/previous controls and captions. | Third-party packages may include these, but add bundle weight and another accessibility surface. |
| Browser policy | Check current browser compatibility for the browsers you support. | Also depends on your implementation and any framework package. |
Choose a custom implementation only when you need behavior beyond this viewer, such as pinch-to-zoom, keyboard arrow navigation, image rotation or a complex animated transition. If you build those features, preserve the same focus, labeling, Escape and inert-background behavior.
Troubleshooting
The dialog does not open
Confirm that the script runs after the markup exists, the element really is a <dialog>, and you call showModal() from a user action such as a click. A second call while the dialog is already open can throw an InvalidStateError; guard with if (!viewer.open) when your UI can trigger repeated actions.

The image is blank
Inspect the value in data-full and check the browser’s Network panel for a 404, blocked cross-origin response or an incorrect relative path. Set src only after selecting the button and verify that the server returns an image MIME type.
Focus does not return
Keep the opener in a variable outside the click handler and restore it in the dialog’s close event. Do not remove or replace the thumbnail node while the dialog is open; if your framework rerenders it, store a stable reference or a selector and test that the element is still connected.

FAQ
Can I open the viewer from a link instead of a button?
You can, but a button is the correct control when the action opens a modal. If you use a link for progressive navigation, keep its destination meaningful when JavaScript is unavailable and prevent its default action only after the dialog opens successfully.
Should the full-size image be preloaded?
Usually no. Loading it on activation saves bandwidth for visitors who never open the viewer. Preload only when opening latency is more important than initial page weight and the image is highly likely to be viewed.
How do I add captions?
Store a caption in another data attribute, set a text element inside the dialog when opening, and associate it with the image using visible text or an appropriate aria-describedby relationship.

1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesFrequently Asked Questions
Does a native dialog prevent scrolling of the page behind it?
A modal dialog makes the document inert, but test your target browsers and add a page-level scroll lock only if your layout still scrolls behind the dialog.
Can the same dialog show video or PDFs?
The focus and close pattern is reusable, but replace the image element with the relevant media element and provide an equivalent accessible name and loading state.
The Bottom Line
For an HTML lightbox, use a real thumbnail button, responsive image attributes and one native modal <dialog>. Set the selected image at activation, provide visible close and Escape dismissal, and restore focus when closing.
