ELI5: Explain Like I'm 5

EPUB

Hey kiddo! Have you ever read a book on your tablet or computer? Did you know that there's a special file format for that called EPUB?

Imagine you have a room and you want to fill it up with books. Each book has a different cover, font, and paper color, right? Well, think of EPUB as a way to make a digital book, with all those features and more.

An EPUB book is like a digital puzzle made up of different pieces. These pieces are made up of files, and each file has a different job. For example, one file might have the words of the book, another might have the cover image, and others might have the author's name and other important information.

Now, because EPUB is designed for digital books, it can do some cool things that printed books can't. For example, you can change the font size or font style, and the book will still look great. You can also search the book for specific words or phrases, just like you would on a website.

Here's another cool thing about EPUB: It's pretty smart. When you open an EPUB book, it looks at the screen size of your device and figures out how to display the text and images in the best way possible. That means you can read an EPUB book on any device, big or small, and it will always look great.

So there you have it, kiddo. EPUB is a special file format for digital books that lets you read your favorite stories on your tablet or computer. With EPUB, you can change the font size, search for specific words, and more. Cool, huh?
