Multiple Styles Will
Cascade Into One
Style
sheets allow style information to be specified in many ways. Styles can be
specified inside a single HTML element, inside the <head> element of an
HTML page, or in an external CSS file. Even multiple external style sheets can
be referenced inside a single HTML document.
Cascading
Order
What
style will be used when there is more than one style specified for an HTML
element?
Generally
speaking we can say that all the styles will "cascade" into a new
"virtual" style sheet by the following rules, where number four has
the highest priority:
Browser
default
External
style sheet
Internal
style sheet (inside the <head> tag)
Inline
style (inside an HTML element)
So,
an inline style (inside an HTML element) has the highest priority, which means
that it will override a style declared inside the <head> tag, in an
external style sheet, or in a browser (a default value).
Note: If the external
style sheet link is placed below the internal style sheet in HTML <head>,
the external style sheet will override the internal style sheet.
