How many media queries

This example applies styles when the user's primary input mechanism such as a mouse can hover over elements:. Many media features are range features , which means they can be prefixed with "min-" or "max-" to express "minimum condition" or "maximum condition" constraints.

For example, this CSS will apply styles only if your browser's viewport width is equal to or narrower than px:. If you create a media feature query without specifying a value, the nested styles will be used as long as the feature's value is not zero or none , in Level 4. For example, this CSS will apply to any device with a color screen:.

If a feature doesn't apply to the device on which the browser is running, expressions involving that media feature are always false. For example, the styles nested inside the following query will never be used, because no speech-only device has a screen aspect ratio:. For more Media feature examples, please see the reference page for each specific feature. Sometimes you may want to create a media query that depends on multiple conditions.

This is where the logical operators come in: not , and , and only. Furthermore, you can combine multiple media queries into a comma-separated list ; this allows you to apply the same styles in different situations. In the previous example, we've already seen the and operator used to group a media type with a media feature. The and operator can also combine multiple media features into a single media query. The not operator, meanwhile, negates a media query, basically reversing its normal meaning.

The only operator prevents older browsers from applying the styles. Note: In most cases, the all media type is used by default when no other type is specified. However, if you use the not or only operators, you must explicitly specify a media type. And hey, good luck with your project! I've managed to do a bit more work on my project but I've been so busy with work and Treehousing I just haven't had the time : But I think I'm getting there with reducing my media queries a little bit and finding a structure to reduce breakpoints, so maybe your idea was the best one.

It depends on the site layout and what features so there's not a hard and fast rule, but I'd say too many is better than not enough. I usually use 3 major breakpoints because it's easier to keep organized. Obviously you want to limit the gross calls to the sever, so it's best to have them on fewer style sheets rather than importing more external documents.

Making a website with an adaptable layout is called Responsive Web Design. A Media query is a CSS3 feature that makes a webpage adapt its layout to different screen sizes and media types. We can target different media types under a variety of conditions. We start defining media queries with media rule and later include CSS rules inside the curly braces.

The media rule is also used to specify target media types. Inside the parenthesis, we set a condition. Other elements should be dealt with in similar ways. Such a discussion should include maximum facilitated usage, element importance based on visible page regions , facilitated reading, and intuitive navigation. Among these categories, one of the most important components is content width adjustment. For example, the so-called fluid grid systems have set elements, i.

In this way, all elements in the responsive web design system automatically adjust with the size of the page. Therefore, I will just mention some major frameworks that support such behavior: Bootstrap , Unsemantic , and Brackets. Until recently, website optimization was a term exclusively reserved for customization of functionality based on different web browsers. Alongside the inevitable struggle with different browser standards that we face today, this term now assumes adapting to devices and screen sizes with responsive web design as well.
