Option A (easiest): Use a popup/modal plugin

Look for a plugin that supports “open popup on click” and lets you put text content inside.

Common options:

• Popup Maker (popular; good for “click to open” text popups)

• Elementor (if you use Elementor Pro, it has Popups built-in)

• Kadence Blocks / Spectra / GenerateBlocks (some setups can do modals; depends on your stack)

Generic steps (Popup Maker-style):

1. Install/activate the popup plugin.

2. Create a new Popup called “Full Article”

3. Paste your article text into the popup content.

4. Set popup size, scrolling, and show the close “X”.

5. Create a button/link on your page that says “Read full Article”

6. Link that button to the popup trigger (usually the plugin gives you a CSS class like popmake-123 or a shortcode trigger).

This is the cleanest if you don’t want to mess with code.
