The style global attribute contains CSS styling declarations to be applied to the element. Note that it is recommended for styles to be defined in a separate file or files. This attribute and the <style> element have mainly the purpose of allowing for quick styling, for example for testing purposes.
Usage note: This attribute must not be used to convey semantic information. Even if all styling is removed, a page should remain semantically correct. Typically it shouldn't be used to hide irrelevant information; this should be done using the hidden attribute.
