In order to re-render parts or entire pages, the process of recalculating page element position and geometry (geometries) is called reflow. Because Reflow is a user intercept (user-blocking) operation in a browser, learn how to reduce the number of reflow, and different document properties (DOM level (DOM depth), CSS efficiency, no type of style change), the numb

Before the discussion page redraws, reflow. Need to have some understanding of the page rendering process, the page is how to display HTML, CSS, etc. to the browser, the following flowchart shows the browser to the page rendering process. Different browsers may be slightly different. But basically, they are similar.High-performance Web development-page rendering, redrawing, reflow1. The browser parses the obtained HTML code into 1 dom trees, each tag

included in the render tree because Visibility:hidden affects the layout (layout) and occupies space. According to CSS2 's standard, each node in the render tree is called box dimensions, which understands that the page element is a box with padding, margins, borders, and positions.4. Once the render tree is constructed, the browser can draw the page based on the render tree.Second, reflow and redraw1. Some (or all) of the render tree needs to be reb

Copy Code code as follows: Repaint (redraw), the appearance of the element changes when the repaint changes, and occurs without changing the layout, such as changing the outline,visibility,background color without affecting the DOM structure rendering. Reflow (rendering), and repaint difference is that he will affect the DOM of the structure rendering, and he will trigger the repaint, he will change himself with all the parents of the element

This article mainly introduces the usage of Repaint and Reflow in JavaScript, which is the basic knowledge in JS beginners, if you want to use a CSS wildcard *, do you often hear from senior colleagues or some front-end predecessors? CSS selector layers cannot exceed three layers. CSS class selector should be used whenever possible, writing HTML uses less tables, and the structure should be as simple as possible-the DOM tree should be small .... with

1. How the browser's rendering engine works:(1) Parse HTML, generate DOM tree. Parsing an HTML document, converting HTML tags in a tree or JS-generated tags to a DOM node, which is called the content tree.(2) Build a rendering tree, parse style, generate style Rules, parse CSS (including external CSS files and style elements, and JS-generated styles), calculate the style of the node according to the CSS selector, create another tree-the rendering tree.(3) according to (1) and (2) Start the layou

Before the discussion redraw, reflow. Need to have some understanding of the rendering process, how to put HTML in conjunction with CSS and other explicit to the browser, the nextThe flowchart shows the process of rendering the browser pair. Different browsers may be slightly different. But basically, they are similar.1. The browser parses the acquired HTML code into 1 dom trees, each tag in the HTML is 1 nodes in the DOM tree, and the root node is th

Do you often listen to senior or some front-end predecessors said that can not use CSS wildcard *,CSS selector cascade can not be more than three layers, CSS as far as possible using class selector, writing HTML less use table, the structure should be as simple as possible-dom tree small .... And so on, I've probably known that using wildcards or too many CSS selectors may degrade performance, so why not use the table label I have been in a daze, and then do so, but I know Repain and

Dom programming can be the most time-consuming place to rearrange and redraw.1. What is reflow and redrawAfter the browser has downloaded all the components in the page--html tags, JavaScript, CSS, and images will parse the resulting two internal data structures--dom tree and render tree.The DOM tree represents the page structure, and the render tree represents how the DOM nodes are displayed. Each node in the DOM tree that needs to be displayed has a

that Visibility:hidden hidden elements are still included in the render tree, because Visibility:hidden affects the layout and occupies space. According to the CSS2 standard, each node in the render tree is called box dimensions, which understands that the page element is a box with padding, margins, borders, and positions.4. Once the render tree is built, the browser can draw the page based on the render tree. Such as:Reflow and Redraw1. When part (or all) of the render tree needs to be rebuil

1. repaintrepainting occurs when the appearance of an element is changed but the layout is not changed, such as changing visibility, outline, and foreground. When repaint occurs, the browser verifies the visibility attribute of all other nodes on the DOM tree. 2. If a Reflow change involves an element layout (such as width), the browser discards the original attribute, recalculates the result, and passes the result to the render to re-depict the page

1. What is repaint/reflow? During the page loading process, the document structure needs to be parsed, and various styles need to be combined to calculate the page length, and then render the page through the browser. This entireThe process is still complex in detail, which is full of repaint and reflow. Each element in the DOM structure has its own box (model ).(Defined by the browser or developer) to calc

Countermeasure: Adjust the feeding device, clean the feeding platform, and replace the bad parts or feeding device. When there is a throwing phenomenon, you can first ask the on-site personnel to describe it, then, we can find out the problem based on the observation and analysis, so that we c
