HTML预览区域
HTML Preview Area
HTML 预览工具是一个网页应用，允许用户实时查看HTML代码的渲染效果，帮助用户更好地编写和格式化网页文档。
此HTML预览工具支持标准的HTML语法，包括标签、属性、CSS样式和JavaScript脚本等，同时还支持导出为HTML格式。
HTML（超文本标记语言）是创建网页的标准标记语言。它描述了网页的结构，由一系列的元素组成，这些元素告诉浏览器如何显示内容。
HTML元素通过标签来标记，浏览器不会显示HTML标签，而是使用它们来渲染页面内容。
HTML文件通常以.html或.htm为扩展名保存。现代网页还会结合CSS（用于样式）和JavaScript（用于交互）来增强用户体验。

</html>HTML Previewer is a web application that allows users to view the rendering effect of HTML code in real-time, helping users better write and format web documents.
This HTML preview tool supports standard HTML syntax, including tags, attributes, CSS styles, and JavaScript scripts, and also supports exporting to HTML format.
HTML (Hypertext Markup Language) is the standard markup language for creating web pages. It describes the structure of a web page and consists of a series of elements that tell the browser how to display the content.
HTML elements are marked with tags, which browsers don't display but use to render the page content.
HTML files are typically saved with a .html or .htm extension. Modern web pages also incorporate CSS (for styling) and JavaScript (for interactivity) to enhance the user experience.
