XML is widely used to build and manage user interfaces. It defines and displays the interface content through the following steps: Define interface elements: XML uses tags to define interface elements and their properties. Building a hierarchy: XML organizes interface elements according to hierarchical relationships to form a tree structure. Using Stylesheets: Developers use stylesheet languages ??such as CSS or XSL to specify the visual appearance and behavior of elements. Rendering process: A browser or application uses an XML parser and stylesheet to parse an XML file and render interface elements to make it visible on the screen.
XML for interface display
XML (Extensible Markup Language) is widely used in building and managing user interfaces (UIs). It enables developers to design and modify interfaces easily by defining the hierarchy of interface elements. XML provides a standardized way to describe interface elements, allowing them to render across platforms and devices.
How to display interface content in XML
- Define interface elements: XML uses tags to define interface elements, such as
<button></button>,<label></label>and<input>. Each tag represents a specific interface element and its properties. - Building hierarchies: XML organizes interface elements based on their hierarchy relationships. The parent element contains the child element, forming a tree-like structure. This hierarchy defines the layout and content flow of the interface.
- Use style sheets: XML itself does not contain style information. Instead, developers use stylesheet languages ??such as CSS or XSL to specify the visual appearance and behavior of elements.
- Rendering process: Browser or other applications use XML parsers and stylesheets to parse XML files. The parser creates a document object model (DOM), which represents the hierarchy of the interface. The browser then applies a stylesheet to render the interface elements so that they are visible on the screen.
Advantages
- Extensibility: The XML's tag structure enables it to easily add or remove elements as needed.
- Platform Independent: XML files can be rendered on any platform that supports XML parsers.
- Easily Maintenance: XML provides a clear interface description that makes it easy to maintain and update.
- Accessibility: XML supports accessibility features, such as describing interface elements in a screen reader.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
