Easy and predictable media queries
npm install media-blenderEasy and predictable media queries
``bash`
npm install --save media-blender
The breakpoints are defined with a SCSS map. The smallest breakpoint should start with 0, and the largest should only have one value if the other is infinity:
`scss
@import 'media-blender';
$media-breakpoints: (
mobile: 0 767,
tablet: 768 991,
desktop: 992 1199,
large: 1200
);
`
The above values are overriding the default values. The default values are:
`scss`
$media-breakpoints: (
small: 0 543,
mobile: 544 767,
tablet: 768 991,
desktop: 992 1199,
large: 1200
) !default;
The media mixin is receiving one or more parameters - the breakpoints we want to match.
#### Small mobile screens only
Source:
`scss`
@include media(small) {
.element {
color: red;
}
}
Compiled:
`css`
@media (max-width: 543px) {
.element {
color: red;
}
}
#### Tablet only
Source:
`scss`
@include media(tablet) {
.element {
color: red;
}
}
Compiled:
`css`
@media (min-width: 768px) and (max-width: 991px) {
.element {
color: red;
}
}
#### Desktop
`scss`
@include media(desktop large) {
.element {
color: red;
}
}
Compiled:
`css`
@media (min-width: 992px) {
.element {
color: red;
}
}
#### Tablet and large
`scss`
@include media(tablet large) {
.element {
color: red;
}
}
Compiled:
`css`
@media (min-width: 768px) and (max-width: 991px), (min-width: 1200px) {
.element {
color: red;
}
}
#### Retina support
The mixin also supports retina screens via the retina query. It can be used alone,
or in combination with other breakpoints.
##### Using only retina
`scss`
@include media(retina) {
.element {
color: red;
}
}
Compiled:
`css`
@media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) {
.element {
color: red;
}
}
###### Combining retina with breakpoints
`scss`
@include media(small mobile tablet retina) {
.element {
color: red;
}
}
Compiled:
`css`
@media (max-width: 991px) and (-webkit-min-device-pixel-ratio: 2), (max-width: 991px) and (min-resolution: 192dpi) {
.element {
.color: red;
}
}
#### Desktop-first and mobile-first support
We make writing mobile-first or desktop-first oriented media queries easier than ever
by introducing the up and down keywords. You can now say tablet up, and this willtablet down
target tablets, and all other devices with a screen of at least that size. The reverse
goes for . This will include all devices with a screen size no larger than
that defined for the tablet upper breakpoint. This also works for your custom breakpoints,
if you define them. It relies on the breakpoints, not their order of definition in the map.
##### Using down syntax`scss`
@include media (tablet down) {
.element {
color: red;
}
}
Compiled:
`css`
@media (max-width: 991px) {
.element {
color: red;
}
}
##### Using up syntax
`scss`
@include media (tablet up) {
.element {
color: red;
}
}
Compiled:
`css`
@media (min-width: 768px) {
.element {
color: red;
}
}
#### Orientation
Other than the breakpoints, you can also specify orientation, as an optional second
argument to the mixin. For example, you can specify all mobile devices and tablets in
landscape mode as so:
`scss`
@include media(small mobile tablet, landscape) {
.element {
visibility: hidden;
}
}
Compiled:
`css`
@media (max-width: 991px) and (orientation: landscape) {
.element {
visibility: hidden;
}
}
The mixin and its functions are unit tested using True.
All of the tests are defined in the test/ directory and are SCSS files themselves. To add.scss
your own tests, create a new file in test/ and add the file name to the test_sass.js
file. The tests are run using Mocha.
To run the tests, run this command:
`bash`
npm run test
Additionally, tests and linters can be run continuously through the watch mode, via:
`bash``
npm run watch
* Updated default breakpoints (Bootstrap 4 values)
