Adds an [expand] shortcode that wraps content in a native HTML `<details>` toggle. No JavaScript, no settings page, no bloat.

== Description ==

A single shortcode you can drop into any post, page, or text widget to get a click-to-expand "read more" toggle. The output is a native HTML `<details>` element styled with a small inline stylesheet — nothing else.

The point is the absence of features. There is no settings page, no animation library, no editor block panel with twelve toggles. If you need a read-more on one paragraph in one post, you do not want a plugin that wants to manage your whole site.

Usage:

`[expand title="My title"]
The content goes here.
<img src="even-images-can-go-in-here.jpg" />
And wrap up with a closing expand tag.
[/expand]`

Supports a custom CSS class via `[expand class="my-class"]` and works with WordPress oEmbeds and other shortcodes nested inside.

== Installation ==

1. Upload `/simple-expand/` to the `/wp-content/plugins/` directory.
2. Activate the plugin through the Plugins menu in WordPress.
3. Place `[expand]` shortcodes in your posts or pages.

== Frequently Asked Questions ==

= Does this work in the block editor? =

Yes. The shortcode renders inside any paragraph or shortcode block.

= Can I style it myself? =

Yes. Add your own CSS targeting `details.jhse-expand` (or pass `class="my-class"` to the shortcode and target that).

== Screenshots ==

1. Closed Simple Expand.
2. Open Simple Expand with HTML inside.
