Reflow and repaint are processes in web browsers that occur when the layout or visual appearance of a webpage changes, impacting performance and user experience. Reflow recalculates the positions and dimensions of elements, while repaint updates the visual representation without affecting layout.
CSS parsing is the process by which the browser interprets and converts CSS code into a structure that can be used to style elements on a web page. This involves tokenizing the CSS, constructing a style tree, and applying the styles in accordance with the CSS specification and the document's DOM structure.
DOM manipulation refers to the process of dynamically changing the structure, style, or content of a web page using programming languages like JavaScript. It enables developers to create interactive and dynamic web experiences by accessing and modifying the Document Object Model of a webpage in real-time.
Browser rendering is the process by which a web browser interprets HTML, CSS, and JavaScript to display a web page visually on the user's screen. This involves constructing the Document Object Model (DOM), applying styles, and executing scripts to create an interactive and visually coherent representation of the web content.
Computed styles refer to the final styles applied to a web element after all CSS rules have been processed, including those from external stylesheets, internal styles, and inline styles. They provide a comprehensive view of an element's styling as rendered by the browser, which is essential for debugging and understanding CSS behavior in web development.
UI rendering is the process of converting code into visual elements that users interact with on a screen, ensuring that the interface is both functional and aesthetically pleasing. It involves efficiently updating the display in response to user actions or data changes, balancing performance with user experience.
Concept
The Document Object Model (DOM) is a programming interface for web documents, representing the page structure as a tree of objects that can be manipulated with scripting languages like JavaScript. It enables dynamic content updates and interactive web applications by allowing scripts to change the document structure, style, and content on-the-fly.
CSSStyleSheet is an interface in the DOM that represents a single CSS stylesheet, allowing developers to manipulate its rules dynamically. It provides methods and properties to access, modify, and manage the CSS rules and styles applied to a document programmatically, enhancing the interactivity and responsiveness of web applications.
A declaration block is a section of CSS code enclosed in curly braces that contains one or more declarations, each specifying a style property and its value. It is used to define the styling rules for HTML elements, allowing for consistent and efficient design across web pages.
Concept
The HTML DOM (Document Object Model) is a programming interface for web documents, representing the page so that programs can change the document structure, style, and content dynamically. It provides a structured representation of the document as a tree of objects, enabling developers to interact with and manipulate the page using languages like JavaScript.
Web browser rendering is the process by which browsers translate HTML, CSS, and JavaScript into a visually structured page that users can interact with. This intricate process involves parsing these languages, constructing a Document Object Model (DOM) tree, and painting the elements on the screen in an efficient manner to ensure a seamless user experience.
