Question 45129 in Html Question posted in
Some basic documentation can be found here.

Where is the CSS spec that says the "!important" takes precedence over inline element styles? – Html

In all modern browsers, CSS rules declared with the !important keyword take precedence over all other declarations, even including those made inside the element style attribute.

Where in the CSS spec does it say it should override element style attribute rules? I am trying to find it here but am not having any luck:

https://www.w3.org/TR/css-cascade-5/#importance

I really don’t like that it overrides element styles, and am wondering if this behavior was even in the specs to begin with.

    Right at the top of the section on the cascade sort

    The cascade sorts declarations according to the following criteria, in descending order of priority:

    The very first entry is:

    Origin and Importance

    which includes all the !important rules.

    The third entry is:

    Element-Attached Styles

    This behavior is described with the sentence:

    An important declaration takes precedence over a normal declaration.

    (emphasis mine)

    Where an important declaration has !important at the end and:

    All other declarations are normal (non-important).

    Source: https://www.w3.org/TR/css-cascade-5/#importance

    If you don’t like that important styles have this trait, then don’t use them—find a way to override non-inline styles using the other precedence rules. Generally, I would recommend using important styles only when truly necessary (e.g. to override a style that is defined inline by a third party).
