It is generally not recommended to put CSS styles in the body of HTML because it goes against the principle of separating content and presentation, which is a key concept in web design.
Separating content and presentation means that the HTML document should contain only the content, while the presentation (styling) should be done in a separate file or section of the document, such as the <head> section or an external CSS file.
There are a few reasons why it is not ideal to put CSS styles in the body of HTML:
- Readability: Putting CSS styles in the body of HTML can make the HTML code less readable and harder to maintain. This is because the CSS code is mixed in with the HTML content, making it harder to distinguish between the two.
- Reusability: If the same styles are used throughout the document, it is more efficient to define them in a separate CSS file or section rather than repeating them in the body of HTML.
- Maintenance: If changes need to be made to the styles, it is easier to make them in a separate CSS file or section rather than searching for and editing them in the body of HTML.
- Best practices: Separating content and presentation is considered a best practice in web design, and adhering to best practices can help make your code more maintainable and easier to understand for other developers who may need to work on it in the future.
Overall, while it is possible to put CSS styles in the body of HTML, it is not recommended due to the potential drawbacks mentioned above.

Additionally, putting CSS styles in the body of HTML can also lead to specificity and cascading issues. CSS rules have a specificity hierarchy, which determines which styles take precedence when multiple rules target the same element. If styles are defined inline within the body, they have higher specificity than external or internal CSS stylesheets. This can make it difficult to override or modify styles later on.
Moreover, separating styles from the body of HTML allows for better organization and structure of code. It enables developers to easily locate and modify styles without having to sift through the HTML content. It also promotes code reusability, as styles can be applied to multiple elements or pages by simply linking to an external CSS file or using a shared class or ID.
Lastly, maintaining a clear separation between content and presentation improves accessibility and device compatibility. External CSS files can be cached by browsers, leading to faster loading times and reduced bandwidth usage. This is not possible if the styles are embedded within the body of HTML. Additionally, using external CSS allows for a consistent styling across multiple web pages, making it easier to create responsive designs that adapt to different screen sizes and devices.

Furthermore, by separating CSS styles from the body of HTML, it promotes a more modular and scalable approach to web development. With a separate CSS file or section, styles can be easily reused and applied to different HTML documents without duplicating code. This improves efficiency, reduces code repetition, and makes it easier to maintain and update styles across multiple pages.
Another advantage of separating styles from the body of HTML is better code organization and readability. When CSS styles are placed in a separate file or section, it allows for a clean and structured HTML code that focuses on the content. This separation makes it easier for developers to understand and navigate the codebase, improving collaboration and future maintenance.
In summary, it is best to adhere to best practices and separate CSS styles from the body of HTML to maintain code readability, reusability, scalability, and to prevent specificity and cascading issues. Separating content and presentation allows for better organization, maintainability, accessibility, and device compatibility.
