HTMLslide

HTMLslide is a lightweight framework that facilitates the creation of web-based slide presentations. It uses standard HTML, CSS, and JavaScript to transform a series of HTML elements into a slide deck that can be navigated with keyboard shortcuts or via touch gestures. The library was initially released in 2014 by a group of open‑source developers who sought a simple alternative to proprietary presentation tools such as PowerPoint and Keynote.

Installation is straightforward; developers can download the latest build from the official repository or include the script via a CDN link. Once integrated, a slide deck is constructed by wrapping content in <section> tags, each of which represents a separate slide. HTMLslide automatically applies a grid layout and minimal styling, offering options for custom styles through a configuration object. The framework also supports nested slides, allowing sub‑sections to be displayed as dictated by indentation levels.

Key features of HTMLslide include responsive design, custom slide transitions, and the ability to embed multimedia content such as images, video, and audio directly into the slide markup. It also provides a set of keyboard bindings—arrow keys, space bar, and page up/down—for slide navigation. For advanced use cases, HTMLslide exposes a small API that allows developers to programmatically control the slide state, register event listeners for slide changes, and define custom transitions.

HTMLslide is distributed under the MIT license, which encourages both personal experimentation and integration into commercial projects. Its simplicity makes it a popular choice for educators, developers, and designers who need a lightweight, modern way to deliver interactive slide content on the web.
