Media query can i use
Use mediaqueries to set the background-color to lavender if the viewport is pixels wide or wider, to lightgreen if the viewport is between and pixels wide.
If the viewport is smaller than pixels, the background-color is lightblue:. Create a responsive navigation menu displayed horizontally on large screens and vertically on small screens :. Media queries can also be used to change layout of a page depending on the orientation of the browser. You can have a set of CSS properties that will only apply when the browser window is wider than its height, a so called "Landscape" orientation. Use mediaqueries to set the text color to green when the document is displayed on the screen, and to black when it is printed:.
Comma separated list : add an additional media query to an already existing one, using a comma this will behave like an OR operator :. We just launched W3Schools videos.

Used for combining multiple media features together into a single media query, requiring each chained feature to return true for the query to be true.
It is also used for joining media features with media types. Used to negate a media query, returning true if the query would otherwise return false. If present in a comma-separated list of queries, it will only negate the specific query to which it is applied. If you use the not operator, you must also specify a media type. Note: In Level 3, the not keyword can't be used to negate an individual media feature expression, only an entire media query.
Applies a style only if an entire query matches. It is useful for preventing older browsers from applying selected styles. When not using only , older browsers would interpret the query screen and max-width: px as screen , ignoring the remainder of the query, and applying its styles on all screens.
If you use the only operator, you must also specify a media type. Commas are used to combine multiple media queries into a single rule. Each query in a comma-separated list is treated separately from the others Thus, if any of the queries in a list is true , the entire media statement returns true. In other words, lists behave like a logical or operator. Both em and px are valid units, but em works better if the user changes the browser text size.
Also consider using Level 4 media queries to improve the user's experience. For example, prefers-reduced-motion to detect if the user has requested that the system minimize the amount of animation or motion it uses. Because media queries provide insights into the capabilities—and by extension, the features and design—of the device the user is working with, there is the potential that they could be abused to construct a "fingerprint" which identifies the device, or at least categorizes it to some degree of detail that may be undesirable to users.
Because of this potential, a browser may opt to fudge the returned values in some manner in order to prevent them from being used to precisely identify a computer. A browser might also offer additional measures in this area; for example, if Firefox's "Resist Fingerprinting" setting is enabled, many media queries report default values rather than values representing the actual device state. Introduced in Media Queries Level 4 is a new range syntax that allows for less verbose media queries when testing for any feature accepting a range, as shown in the below examples:.
