User interface markup language

A user interface markup language is like a special code that helps people create things that we see and use on computers and phones. You know how when you use a computer or a phone, you tap buttons, type in things, and move things around? All of these things are part of the user interface.

A user interface markup language helps people create the buttons, text fields, pictures, and everything else you see on a user interface. It’s like building with Legos – you get to use special pieces to make different things. But instead of Legos, you use a markup language like HTML, CSS, or XML to make the user interface.

When you open up a webpage or an app, the user interface markup language is what helps your device know what to show you. The code tells your device what size and shape each button should be, what color it should be, and where it should be located on the page. It also tells your device what happens when you tap a button or type something into a text field.

So, a user interface markup language is like a special language that helps people create the things we see and use on computers and phones. And without it, we wouldn't be able to use our devices the way we do!
