Photo gallery

As explained in Build a Website with ChatGPT

A photo gallery is a web page or interface that presents a collection of photographs, often with controls for viewing larger versions.

A photo gallery is a single web page that presents a collection of photographs as smaller thumbnail images. Selecting a thumbnail reveals a larger version, letting visitors browse several photos without leaving the page. section 10.1 section 10.2.3

Thumbnails keep the first visit lighter because full-size photos can be several megabytes each. Create a reduced copy of every image, use a consistent filename such as image01-thumbnail.jpg, and keep the matching full-size file without -thumbnail. section 10.2.3

A lightbox provides the larger view as a temporary, slightly transparent overlay. Clicking a thumbnail creates the overlay and places the full-size image in it; clicking the page removes the overlay and returns the visitor to the gallery. section 10.3

Use Flexbox for the gallery container so photo figures do not simply run down the page one by one. Centering and wrapping the content lets the image grid adapt to the browser window’s dimensions. section 10.5

A practical gallery page includes:

• A header with a logo and site title. section 10.1
• A main area with a gallery title, viewing instructions, and thumbnail figures with alt text and captions. section 10.6
• A footer with a copyright notice. section 10.1
• Separate HTML, CSS, and JavaScript files, with JavaScript handling the lightbox. section 10.6

Prompting for a gallery

Ask for HTML for the header, instructions, and every specified image figure; request CSS for colors, fonts, and Flexbox containers; then request JavaScript for a lightbox overlay. Check that the generated HTML includes every image rather than a placeholder comment, then save the files as index.html, styles.css, and script.js. section 10.6

Customize the page by editing visible text, image alt values, captions, colors, type sizes, spacing, and overlay transparency. Preserve the surrounding HTML tags, quotation marks, and px units while making those edits. For themed collections, create one gallery page at a time and add navigation between pages. section 10.8

How Build a Website with ChatGPT covers it

How deep it goes

Explains thumbnail preparation, Flexbox layout, lightbox behavior, generated code files, and basic customization without requiring manual lightbox coding.

Examples

Uses a nine-image photography gallery, a three-thumbnail lightbox demonstration, and a copyable code-generation prompt.

What it assumes

Assumes prepared photos, a logo, title, font choices, and a color scheme while supplying code-generation guidance for noncoders.

What you can do after

Builds a photo-gallery page with thumbnails, a Flexbox grid, and a clickable lightbox through generated HTML, CSS, and JavaScript.

How it connects

Connects thumbnails, lightbox overlays, Flexbox, HTML, CSS, JavaScript, alt text, captions, and navigation.
