海外TECH	DEV Community	How web browsers work - the render tree (part 7, with illustrations)💻 ⏳	https://dev.to/arikaturika/how-web-browsers-work-the-render-tree-part-7-with-illustrations-24h3	How web browsers work the render tree part with illustrations The trees built in the parsing phase DOM CSSOM are combined into something called the render tree This is used to compute the layout of all visible elements that will be painted to the screen in the end The purpose of the render tree is to make sure the content of the page will paint the elements in the correct order It will be serverd as input to the painting process that will display the pixels on the screen The DOM and the CSSOM are created using the HTML and the CSS files Both of these files hold different types of information and the trees are different structures so how does the render tree gets created COMBINING THE DOM WITH THE CSSOMThe browser will start doing its magic at the root of the DOM tree and traverse every visible node Some of the nodes like script or meta tags are not visible so they are ignored There are also nodes that will be hidden with the use of CSS the display none property for example and they will also be ignored We are only interested in the visible nodes because only they matter for the input on the screen For each visible node that s found in the DOM the coresponding rules will be found in the CSSOM and they will be applied The result of these steps will be a render tree that contains all visible nodes with content and styles THE LAYOUT REFLOW STAGEThe render tree holds information on which nodes are displayed even if invisible along with their computed styles but not the dimensions or location of each node What needs to be done next is calculate the exact position of those nodes within the viewport of the device inside the browser window and their size This is the stage called layout in Chrome Opera Safari and Internet Explorer or reflow in Firefox but they mean the same thing The browser starts this process at the root of the render tree and traverses it The reflow step doesn t happen only once but every time we change something in the DOM that affects the layout of the page even partially Examples of situations when the positions of the elements is recalculated are adding or deleting elements from the DOMresizing the browser windowchanging the width the position of an element or floating itLet s get a very basic example of HTML with some CSS applied inline lt DOCTYPE html gt lt html gt lt head gt lt meta name viewport content width device width initial scale gt lt title gt Reflow lt title gt lt head gt lt body gt lt div style width height gt lt div style width height gt This is the reflow stage lt div gt lt div gt lt body gt lt html gt The above code just says that inside the viewport we should have two divs where the second one is nested inside the first The parent div takes up of the viewport and the second of the parent This will look something like this The output of this process is a box like model which captures exactly where each element needs to be on a screen and its size After this step is finished the output is ready to be passed to the next step called the painting stage THE PAINTING REPAINTING STAGEAfter the browser decides which nodes need to be visible and calculates their position in the viewport it s time to paint them render the pixels on the screen This phase it is also known as the rasterization phase where the browser converts each box calculated in the layout phase to actual pixels on the screen Just like the layout stage the painting stage doesn t happen just once but every time we change something in the appearance of the elements on the screen that doesn t affect the layout Examples of these situations are changing the outline of an elementchanging background colorchanging opacity or visibilityPainting means the browser needs to draw every visual part of an element to the screen including text colors borders shadows and replaced elements like buttons and images and it needs to do it super quickly To ensure repainting can be done even faster than the initial paint the drawing to the screen is generally broken down into several layers If this occurs then compositing is necessary LAYERING AND COMPOSITINGTraditionally web browsers relied entirely on the CPU to render web page content But nowadays even the smallest devices have performant GPUs so the attention has turned on finding ways to use this piece of hardware to achieve better performance Compositing is a technique to separate parts of a page into layers painting them separately and composite as a page in a separate thread called the compositor thread When sections of the document are drawn in different layers overlapping each other compositing is necessary to ensure they are drawn to the screen in the right order and the content is rendered correctly Generally only specific tasks get redirected to the GPU and those are the tasks that can be handled by the compositor thread alone In order to find out which elements needs to be on which layer the main thread walks through the layout tree and creates the layer tree By default there s only one layer and how these layers are implemented is browser specific but we can find the elements that would trigger a repaint and create a separate layer for each of them This way the repainting should not be applied to the whole page and in addition this process will use the GPU If we want to hint to the browser that ceratain elements should be on a separate layer we can use the will change CSS attribute There are actually specific properties and elements that signal the creation of a new layer Some of these are lt video gt lt canvas gt and any element which has the CSS properties of opacity a D transform will change and a few others These nodes will be painted onto their own layer along with their descendants KEEP IN MINDBoth of the operations discussed above reflow and repaint are expensive especially on devices with low processing power like phones That s why when dealing with DOM changes we should try to optimze them I will talk more about this in one of the future articles in my DOM series Some actions will trigger a repaint only and some actions both a reflow and a repaint Resource refrences How browsers workDOM Performance

海外TECH	DEV Community	Flutter Web and Rive Animation Tutorial	https://dev.to/suhavi/flutter-web-and-rive-animation-tutorial-5f5k	Flutter Web and Rive Animation TutorialHi This is a beginner to intermediate tutorial for setting up a Flutter web app with Rive animations I recently built a sliding tile game that incorporates Rive animations for the Flutter Hackathon In this tutorial I m going to show you how to add an animation to your Flutter web app and control it through user input We will create a basketball animation that gets triggered each time the user clicks on a button First we ll create the animation If you already have your animation you can skip to this section which will show you how to add your animation to a web app Rive is a free to use platform for designing and creating animations We are going to use a basketball animation that Rive provides as one of their tutorials Here is the animation When you open it there s a Design tab that let s you modify the look of the animation like the colours and original shape of the ball If you switch to the Animate tab you can see the animation run Each animation can have multiple states in this one there s an idle state but you could add more like a rolling state or whatever you might need for your business logic Download the animation in the newest runtime as basketball riv Once we hook it up to Flutter we will be able to play the idle animation when the user performs some action such as clicking a button Create a flutter project that we will be adding the animation to Once the project is created make an assets folder if it doesn t already exist and move your animation file into it I saved mine under assets animations flutter create fluttertutorialcd fluttertutorialflutter run d chromeIt will spin up a demo app for you that looks something like this Next we add the library that is going to help us control play and pause our animation Add to pubspec yaml and run flutter pub get dependencies rive Then in lib main dart import the package import package rive rive dart Now let s add the animation to our app by creating a stateless widget Add this code to the end of lib main dartclass BasketBallAnimation extends StatelessWidget const BasketBallAnimation Key key super key key override Widget build BuildContext context return const Scaffold body Center child RiveAnimation asset animations basketball riv To display this class find the main class MyApp and set home to point to our new widget class MyApp extends StatelessWidget const MyApp Key key super key key override Widget build BuildContext context return MaterialApp title Flutter Demo theme ThemeData primarySwatch Colors blue home const BasketBallAnimation make this change Now when you re run you should see the basketball animation playing Now let s give the widget state this is how we will be able to tell if it s playing or paused class BasketBallAnimation extends StatefulWidget const BasketBallAnimation Key key super key key override State lt BasketBallAnimation gt createState gt BasketBallAnimationState class BasketBallAnimationState extends State lt BasketBallAnimation gt bool isPlaying false override Widget build BuildContext context return Scaffold body const Center child RiveAnimation asset animations basketball riv Next we will add a button that when called will change the value of isPlayingclass BasketBallAnimationState extends State lt BasketBallAnimation gt bool isPlaying false void toggleAnimation setState isPlaying isPlaying override Widget build BuildContext context return Scaffold body const Center child RiveAnimation asset animations basketball riv floatingActionButton FloatingActionButton onPressed toggleAnimation tooltip isPlaying Pause Play child Icon isPlaying Icons pause Icons play arrow Finally we can hook up the RiveController methods The RiveAnimationController is what holds the state of our animation Initially we are going to set it to play our animation named idle This is a SimpleAnimation We will be able to tell if the animation is playing or not by checking the isActive property of the controller We attach this controller to our animation asset by passing it into our animation RiveAnimation asset path to my animation riv controllers controller Here is the updated code with the controller hooked up class BasketBallAnimationState extends State lt BasketBallAnimation gt late RiveAnimationController controller bool get isPlaying gt controller isActive void toggleAnimation setState controller isActive controller isActive override void initState super initState controller SimpleAnimation idle override Widget build BuildContext context return Scaffold body Center child RiveAnimation asset animations basketball riv controllers controller floatingActionButton FloatingActionButton onPressed toggleAnimation tooltip isPlaying Pause Play child Icon isPlaying Icons pause Icons play arrow Now you should have something that looks like the screen below A basketball animation that starts and stops when the user interacts with the floating button Hope this tutorial helps you The complete code for lib main dart can be found in this gist Happy coding	2022-06-01 05:01:17
