# Themes

With the themes option, you can easily change the color and font family of the entire date picker. We offer **three design styles and over 15 pre-designed themes** for you to choose from. Additionally, you have the freedom to create your own custom theme and save it for future use.

There are two types of themes: built-in and custom.

* **Built-in themes**: These are ready-made themes with predefined colors and styles. Simply select one from the dropdown menu and apply it to your date picker.
* **Custom themes**: These themes allow you to customize every aspect of the date picker, including colors, formatting, and functionality. You can adjust all the settings according to your liking. Once you've created a custom theme, you can save it in JSON format and easily `import or export` it for later use.
