Every website is accessed via devices with different screen sizes and resolutions. Website content responds to these points and adjusts itself to the screen size to display the accurate layout. Since CSS breakpoints are implemented with media queries, they are also sometimes termed media query breakpoints.
The media attribute specifies what media or device the linked document is optimized for. This attribute is used to specify that the target URL is designed for special devices (like iPhone), speech or print media.
CSS 2.1 defines the following media groups: continuous or paged. visual, audio, speech, or tactile. grid (for character grid devices), or bitmap. interactive (for devices that allow user interaction), or static (for those that do not).
@media permalink @media
- SCSS Syntax. @media (width <= 700px) { body { background: green; } }
- Sass Syntax. @media (width <= 700px) body background: green.
- CSS Output. @media (width <= 700px) { body { background: green; } }
Media features describe specific characteristics of the user agent, output device, or environment. Media feature expressions test for their presence or value, and are entirely optional. Each media feature expression must be surrounded by parentheses. One may also ask, what is the purpose of a media query?
You may use as many media queries as you would like in a CSS file. Note that you may use the and operator to require multiple queries to be true, but you have to use the comma (,) as the or operator to separate groups of multiple queries. The not keyword can be used to alter the logic as well.
Combining media query expressions
Max-width and min-width can be used together to target a specific range of screen sizes. @media only screen and (max-width: 600px) and (min-width: 400px) {} The query above will trigger only for screens that are 600-400px wide.Inline styles cannot currently contain anything other than declarations ( property: value pairs). You can use style elements with appropriate media attributes in head section of your document. Yes, you can write media query in inline-css if you are using a picture tag.
The max-width property defines the maximum width of an element. If the content is larger than the maximum width, it will automatically change the height of the element. If the content is smaller than the maximum width, the max-width property has no effect.
The browser's viewport is the area of the window in which web content can be seen. This is often not the same size as the rendered page, in which case the browser provides scrollbars for the user to scroll around and access all the content.
What media query breakpoints should I use?
- Mobile portait (320px to 414px) — For devices with 4" to 6.9" screens.
- Mobile landscape (568px to 812px) — Same, but landscape.
- Tablet portait (768px to 834px) — For devices 7" to 10"
- Tablet landscape (1024px to 1112px) — Ditto, but also 12" tablets on portrait.
Media queries are a key part of responsive web design, as they allow you to create different layouts depending on the size of the viewport, but they can also be used to detect other things about the environment your site is running on, for example whether the user is using a touchscreen rather than a mouse.
Responsive Pixel — An Alternative to Media Query for Responsive Resizing. Ever since we started to have computing devices in various sizes, the concept of responsive design came out. And it also comes to attention that the distance between you and the device also varies based on how big the screen is.
Mobile Media Query Not WorkingIf your queries are working in a browser but not on mobile, you might have forgotten to set the viewport and default zoom. This tells the browser to render pages according to the width of the device. Adding it often does the trick for making mobile breakpoints work.
The viewport is the user's visible area of a web page. It varies with the device - it will be smaller on a mobile phone than on a computer screen. This gives the browser instructions on how to control the page's dimensions and scaling.
Use the Media Query Inspector to inspect and trigger the registered breakpoints on a page. In Device Mode, click the icon which looks like staggered bars in the upper left corner of the page, the MQI opens. You can trigger the various breakpoints with a click on a bar.
A media query consists of a media type and can contain one or more expressions, which resolve to either true or false. When a media query is true, the corresponding style sheet or style rules are applied, following the normal cascading rules.
Media queries add no specificity to the selectors they contain, but source order still matters. The above will work because they are ordered correctly.
The z-index CSS property sets the z-order of a positioned element and its descendants or flex items. Overlapping elements with a larger z-index cover those with a smaller one.
