AtomBlock-WebUI是一个合成的Web UI数据集，包含约9,700个完整网页截图，并带有YOLO格式的边界框标注，涵盖了14个UI元素类别，包括基本组件（如按钮、输入框）和语义块级地标（如导航栏、侧边栏、页脚）。与依赖人工标注或启发式DOM解析方法的数据集不同，AtomBlock-WebUI中的边界框是通过Playwright直接从渲染的DOM中提取的，确保了与视觉输出的严格几何对齐。数据集中还注入了真实世界的图像，以缩小合成布局与真实Web环境之间的视觉分布差距。数据集提供了详细的统计信息、目录结构、类别分布、生成流程、使用示例、限制和许可证信息。

AtomBlock-WebUI is a synthetic Web UI dataset featuring ~9,700 full-page web screenshots with YOLO-format bounding box annotations for 14 UI element categories, including both primitive components (buttons, inputs) and semantic block-level landmarks (navigation, sidebar, footer). Unlike datasets reliant on human annotation or heuristic DOM-parsing methods, the bounding boxes in AtomBlock-WebUI are directly extracted from the rendered DOM via Playwright, ensuring strict geometric alignment with the visual output. Real-world images are injected into the synthetic HTML to bridge the visual distribution gap between synthetic layouts and real web environments. The dataset provides detailed statistics, directory structure, class distribution, generation pipeline, usage examples, limitations, and licensing information.
