Focus Mode adds a distraction-free reading experience to your WordPress posts and pages. When enabled, it hides elements like the site header to let users concentrate on the content. An estimated reading time is also displayed at the top of each post or page to inform users how long it will take to read.
This plugin is lightweight and designed for accessibility and readability. Ideal for blogs, long-form content, and educational sites.
