* If a feature relies on the relative ordering of two or more constructs in a stylesheet
(such as the requirement that ''@charset'' must not have any other content preceding it),
(such as the requirement that ''@namespace'' rules must not have any other rules other than
''@import'' preceding it),
it only applies between constructs in the same stylesheet.

<p class='example'>
For example, declarations in style rules from imported stylesheets interact with the cascade
as if they were written literally into the stylesheet at the point of the ''@import''.

Any ''@import'' rules must precede all other at-rules and style rules in a style sheet
(besides ''@charset'', which must be the first thing in the style sheet if it exists),
or else the ''@import'' rule is invalid.
Any ''@import'' rules must precede all other valid at-rules and style rules in a style sheet
(with ''@charset'' counting as an invalid rule), or else the ''@import'' rule is invalid.
The syntax of ''@import'' is:

<pre class='prod'>@import [ <<url>> | <<string>> ] <<media-query-list>>? ;</pre>

Similarly, style rules in a stylesheet imported into a scoped stylesheet
are scoped in the same way.
