Generally speaking, it is recommended to separate your CSS, JavaScript, and HTML as much as possible. Doing this provides a number of benefits such as modularity, reusability, and a better organizational structure for your project that is easier to manage. Additionally, a clean separation of these components is required by many libraries and frameworks, such as React.

For example, your HTML should contain the code that is necessary to render the page correctly, while your CSS should be reserved for styling your elements. Additionally, JavaScript should be used only within an HTML document to add interactive behavior such as form validation and animations.
