To ensure your CSS is well-organized, follow these best practices:
1. Use Inline CSS: Most email clients, like Gmail and Outlook, strip out embedded or external CSS. Therefore, using inline CSS is the safest approach to ensure your styles are applied correctly.
2. Keep It Simple: Email clients have limited support for CSS. Stick to basic styles and avoid complex rules that may not be supported.
3. Use a CSS Reset: A CSS reset can help to normalize the styling across different email clients, ensuring a more consistent appearance.
4. Organize by Sections: Divide your CSS into sections such as typography, layout, and colors. This makes it easier to maintain and update.
5. Minimize Use of Classes and IDs: Since email clients may not fully support complex selectors, it's better to use simple and minimalistic class and ID names.
