HTML validator error
Element style not allowed as child of element div in this context.
At the Framework settings we have an option to put our inline CSS codes to Inline at head and this shouldn't give you that warning anymore.
The reason why we are putting our CSS codes right before our slider's HTML code by default is, that website speed tests are thinking that is better. In real life it doesn't really matter where this style is, as both are perfectly fine for browsers and they will be processed with almost the same speed, so you could choose either options.
