# Introduction The `<data>` tag in HTML is used to assign some custom information to some data which you wish to display on your webpage. For example, if you have a website that lists different products, you can use the `<data>` tag to add the product code to this tag, which will not be visible to the end user. This lab will guide you through using the `<data>` tag in your HTML code. > Note: You can practice coding in `index.html` and learn [How to Write HTML in Visual Studio Code](https://code.visualstudio.com/docs/languages/html).
