'landscape' : 'portrait', - aspectRatio: window.width / window.height, - type: Platform.isTV ? 'tv' : Platform.OS, - direction: isRTL ? 'rtl' : 'ltr', - prefersColorScheme: Appearance.getColorScheme() || 'light' -}); -``` - -### 07. useMediaQuery - -```jsx -const Example = () => { - const device: Partial = useDevice(); - const isDesktopOrLaptop: boolean = useMediaQuery({ - query: '@media (min-width: 1224px)' - }); - const isBigScreen: boolean = useMediaQuery({ query: '@media (min-width: 1824px)' }, device); - const isTabletOrMobile: boolean = useMediaQuery({ query: '@media (max-width: 1224px)' }, device); - const isPortrait: boolean = useMediaQuery({ query: '@media (orientation: portrait)' }, { ...device, width: 1600 }); - - return ( - <> - Device Test! - {isDesktopOrLaptop && You are a desktop or laptop} - {isBigScreen && You have a huge screen} - {isTabletOrMobile && You are a tablet or mobile phone} - Your are in {isPortrait ? 'portrait' : 'landscape'} orientation - - {/* You can also use a function (render prop) as a child */} - {(matches: boolean) => - matches ? You are minimum small device : You are not minimum small device - } - - ); -}; -``` - -### With Components - -```jsx -const Example = () => ( - const device: Partial = useDevice(); - <> - Device Testing! - - You are a desktop or laptop - - You also have a huge screen - - - -); -``` - -To make things more idiomatic to react, you can use camel-cased shorthands to construct media queries. - -For a list of all possible shorthands and value types see https://github.com/Krunal-Kevadiya/rn-custom-style-sheet/tree/main/src/MediaQuery/MediaQuery.ts#L9. - -Any numbers given as shorthand will be expanded to px (1234 will become '1234px'). - -The CSS media queries in the example above could be constructed like this: - -```jsx -const Example = () => { - const device: Partial = useDevice(); - const isDesktopOrLaptop: boolean = useMediaQuery({ minWidth: 1224 }, device); - const isBigScreen: boolean = useMediaQuery({ minWidth: 1824 }, device); - const isTabletOrMobile: boolean = useMediaQuery({ maxWidth: 1224 }, device); - const isPortrait: boolean = useMediaQuery({ orientation: 'portrait' }, device); - - return ( - <> - Device Test! - {isDesktopOrLaptop && You are a desktop or laptop} - {isBigScreen && You have a huge screen} - {isTabletOrMobile && You are a tablet or mobile phone} - Your are in {isPortrait ? 'portrait' : 'landscape'} orientation - - ); -}; -``` - -### `onChange` - -You can use the `onChange` callback to specify a change handler that will be called when the media query's value changes. - -```jsx -const Example = () => { - const handleMediaQueryChange = (matches: boolean) => { - // matches will be true or false based on the value for the media query - }; - const device: Partial = useDevice(); - const isDesktopOrLaptop: boolean = useMediaQuery({ minWidth: 1224 }, device, handleMediaQueryChange); - - return ...; -}; -``` - -```jsx -const Example = () => { - const handleMediaQueryChange = (matches: boolean) => { - // matches will be true or false based on the value for the media query - }; - const device: Partial = useDevice(); - - return ( - - ... - - ); -}; -``` - -## Easy Mode - -That's it! Now you can create your application specific breakpoints and reuse them easily. Here is an example: - -```jsx -const Desktop = ({ children }) => { - const device: Partial = useDevice(); - const isDesktop = useMediaQuery({ minWidth: 992 }, device); - return isDesktop ? children : null; -}; -const Tablet = ({ children }) => { - const device: Partial = useDevice(); - const isTablet = useMediaQuery({ minWidth: 768, maxWidth: 991 }, device); - return isTablet ? children : null; -}; -const Mobile = ({ children }) => { - const device: Partial = useDevice(); - const isMobile = useMediaQuery({ maxWidth: 767 }, device); - return isMobile ? children : null; -}; -const Default = ({ children }) => { - const device: Partial = useDevice(); - const isNotMobile = useMediaQuery({ minWidth: 768 }, device); - return isNotMobile ? children : null; -}; - -const Example = () => ( - <> - - Desktop or laptop - - - Tablet - - - Mobile - - - Not mobile (desktop or laptop or tablet) - - -); -``` - -And if you want a combo (the DRY way): - -```js -const useDesktopMediaQuery = () => { - const device: Partial = useDevice(); - return useMediaQuery({ query: '@media (min-width: 1280px)' }, device); -}; - -const useTabletAndBelowMediaQuery = () => { - const device: Partial = useDevice(); - return useMediaQuery({ query: '@media (max-width: 1279px)' }, device); -}; - -const Desktop = ({ children }) => { - const isDesktop = useDesktopMediaQuery(); - - return isDesktop ? children : null; -}; - -const TabletAndBelow = ({ children }) => { - const isTabletAndBelow = useTabletAndBelowMediaQuery(); - - return isTabletAndBelow ? children : null; -}; -``` - -## Breakpoint - -key (string | number): A breakpoint key (xs, sm, etc.) or a screen width number in px or your provided breakpoint unit(`guideLineBreakpointUnit` props to provider). - -1. Up (upBreakpoint / up-breakpoint) - - Which matches screen widths greater than the screen size given by the breakpoint key (inclusive). - - `Example :` upBreakpoint: 'sm' / (up-breakpoint: sm) - -2.

The HTML Presentation Framework

+

+ Created by Hakim El Hattab and contributors +

+
+ +
+

Hello There

+

+ reveal.js enables you to create beautiful interactive slide decks using HTML. This presentation will show you examples of what it can do. +

+
+ + +
+
+

Vertical Slides

+

Slides can be nested inside of each other.

+

Use the Space key to navigate through all slides.

+
+ + Down arrow + +
+
+

Basement Level 1

+

Nested slides are useful for adding additional detail underneath a high level horizontal slide.

+
+
+

Basement Level 2

+

That's it, time to go back up.

+
+ + Up arrow + +
+
+ +
+

Slides

+

+ Not a coder? Not a problem. There's a fully-featured visual editor for authoring these, try it out at https://slides.com. +

+
+ +
+

Hidden Slides

+

+ This slide is visible in the source, but hidden when the presentation is viewed. You can show all hidden slides by setting the `showHiddenSlides` config option to `true`. +

+
+ +
+

Pretty Code

+ 

+						import React, { useState } from 'react';
+
+						function Example() {
+						  const [count, setCount] = useState(0);
+
+						  return (
+						    ...
+						  );
+						}
+
+

Background Transitions

+

+ Different background transitions are available via the backgroundTransition option. This one's called "zoom". +

+ 
Reveal.configure({ backgroundTransition: 'zoom' })
+
+ +
+

Background Transitions

+

+ You can override background transitions per-slide. +

+ 
<section data-background-transition="zoom">
+
+ +

Clever Quotes

+

+ These guys come in two forms, inline: The nice thing about standards is that there are so many to choose from and block: +

+
+ “For years there has been a theory that millions of monkeys typing at random on millions of typewriters would + reproduce the entire works of Shakespeare. The Internet has proven this theory to be untrue.” +
+
+ +
+

Intergalactic Interconnections

+

+ You can link between slides internally, + like this. +

+
+ +
+

Speaker View

+

There's a speaker view. It includes a timer, preview of the upcoming slide as well as your speaker notes.

+

Press the S key to try it out.

Global State

+

+ Set data-state="something" on a slide and "something" + will be added as a class to the document element when the slide is open. This lets you + apply broader style changes, like switching the page background. +

+
+ +
+

State Events

+

+ Additionally custom events can be triggered on a per slide basis by binding to the data-state name. +

+ 

+Reveal.on( 'customevent', function() {
+	console.log( '"customevent" has fired' );
+} );
+
+
+ +
+

Take a Moment

+

+ Press B or . on your keyboard to pause the presentation. This is helpful when you're on stage and want to take distracting slides off the screen. +

+
+ +
+

    • +
  • How to use breakpoints
    • +
+
+
+

What is Breakpoint

+

+ Breakpoints are the building blocks of responsive design. +

+

+ Use them to control when your layout can be adapted at a particular viewport or device size. +

+
+
+

Default breakpoints

+
+

Each breakpoint (a key) matches with a fixed screen width (a value):

+
    +
  • base, base / extra-small: 0px
    • +
  • sm, small: 480px
    • +
  • md, medium: 768px
    • +
  • lg, large: 992px
    • +
  • xl, extra-large: 1280px
    • +
  • 2xl, double-extra-large: 1536px
    • +
+
+
+
+

How to use breakpoints in CreateStyle

+
+

+ key (string | number): A breakpoint key (xs, sm, etc.) or a screen width number in px or your provided + breakpoint unit(guideLineBreakpointUnit props in provider). +

+

+ If you want to change any of the properties values based on the breakpoint then you can do using this + package same as like provided to native-base(Visit + Native-Bases!) +

+

+ If you provided a value in array form so at that time your given array value will be sorted by + breakpoint key. For example in below example fontSize array will be sorted by breakpoint key) +

+
+

+ Example:
+

+

+ fontSize: ['12@mhs', '14@mhs', '16@mhs', '18@mhs']
+ fontSize: { base: '12@mhs', sm: '14@mhs', md: '16@mhs', lg: '18@mhs' }

+
+

+

How to use breakpoints in MediaQuery

+
+

+ key (string | number): A breakpoint key (xs, sm, etc.) or a screen width number in px or your provided + breakpoint unit(guideLineBreakpointUnit props in provider). +

+
    +
  • 01. upBreakpoint / up-breakpoint

  • 02. downBreakpoint / down-breakpoint
    • +
  • 03. betweenBreakpoint / between-breakpoint
    • +
  • 04. onlyBreakpoint / only-breakpoint
    • +
  • 05. notBreakpoint / not-breakpoint
    • +
+
+
+
+

01. Up (upBreakpoint / up-breakpoint)

+
+

+ Which matches screen widths greater than the screen size given by the breakpoint key (inclusive). +

+

+ Example:
+

+

+ upBreakpoint: 'sm'
+ (up-breakpoint: sm)

+
+

+
+
+
+

02. Down (downBreakpoint / down-breakpoint)

+
+

+ Which matches screen widths less than the screen size given by the breakpoint key (exclusive). +

+

+ Example:
+

+

+ downBreakpoint: 'md'
+ (down-breakpoint: md)

+
+

+
+
+
+

03. Between (betweenBreakpoint / between-breakpoint)

+
+

+ Which matches screen widths greater than the screen size given by the breakpoint key in the first argument + (inclusive) and less than the screen size given by the breakpoint key in the second argument (exclusive). +

+

+ Example:
+

+

+ betweenBreakpoint: ['sm', 'lg']
+ (between-breakpoint: [sm, lg])

+
+

+
+
+
+

04. Only (onlyBreakpoint / only-breakpoint)

+
+

+ Which matches screen widths starting from the screen size given by the breakpoint key (inclusive) and + stopping at the screen size given by the next breakpoint key (exclusive). +

+

+ Example:
+

+

+ onlyBreakpoint: 'md'
+ (only-breakpoint: md)

+
+

+
+
+
+

05. Not (notBreakpoint / not-breakpoint)

+
+

+ Which matches screen widths stopping at the screen size given by the breakpoint key (exclusive) and + starting at the screen size given by the next breakpoint key (inclusive). +

    • +
  • Easy Mode for Media Query
    • +
+
+
+

What is Media Query

+

+ This package allows you to make media-query components in React Native. +

+

+ This can be super useful when you want to render or remove specific elements in DOM depending on the screen + size. Also, you can restructure your DOM (in terms of CSS/Sass Styling) as fit. +

+

+ At times you may need to render components with different device settings than what gets automatically + detected. +

+

+ This is especially useful in a Node environment where these settings can't be detected (SSR) or for testing. +

+ + Possible Keys + +

+ orientation, aspectRatio, deviceAspectRatio, pixelRatio, height, deviceHeight, width, deviceWidth, direction, prefersColorScheme and type +

+ + Possible Types + +

+ + modifier + can be one of: only or not
+ + + type + can be one of: all, screen, tv, ios, android, windows, + macos or web
+ + + aspectRatio + or + deviceAspectRatio + : to decimal number
+ + + pixelRatio + : to decimal number (device pixel density. Visit PixelRatio! + )
+ + + height + , + width + , + deviceHeight + , or + deviceWidth + : to em, rem, cm, mm, in, + pt, pc and px
+ + + direction + can be one of: rtl or ltr
+ + + prefersColorScheme + can be one of: light ro dark
+

+
+
+

MediaQuery Components

+
+ 
+              
+                
+              
+
+

+ To make things more idiomatic to react, you can use camel-cased shorthands to construct media queries. +

+

+ For a list of all possible shorthands and value types see Visit here! +

+

+ Any numbers given as shorthand will be expanded to px (1234 will become '1234px'). +

+

+ The CSS media queries in the example above could be constructed like this: +

+ 
+              
+                
+              
+
+
+
+
+

MediaQuery Components with onChange

+
+

+ You can use the onChange callback to specify a change handler that will be + called when the media query's value changes. +

+ 
+              
+                
+                
+
+ 
+              
+                
+              
+
+
+
+
+

Easy Mode for Media Query

+
+

+ That's it! Now you can create your application specific breakpoints and reuse them easily. Here is an + example: +

+ 
+              
+                
+                
+
+

+ And if you want a combo (the DRY way): +

+ 
+              
+                
+
