Website Design Simulator

Website Design Simulator is a web-based visual layout editor for designing website layouts and previewing changes in real time. It is used for prototyping, learning CSS, and experimenting with web design, and it focuses on letting layouts be adjusted visually instead of by writing code.

The simulator includes drag-and-drop elements, responsive layouts, customizable styles, and a live preview of layout changes. Its controls cover preset themes, layout presets, box shadow settings such as offset, blur, spread, and opacity, as well as component colors, font family, background color, text color, header background, card background, and background pattern. The page also shows a CSS editor and a Copy CSS action, and the sample text says the styles are fully customizable. Its feature list also mentions real-time updates and copy generated styles.

The page describes a range of uses for the tool, including design exploration, quick prototyping, theme development, style experimentation, layout testing, UI mockups, design systems, style guides, and component previews. It also notes that responsive design testing can be explored by checking how layouts behave at different screen sizes, although it says the simulator is not a full responsive testing tool.

Website Design Simulator is presented as free to use. It runs in the browser, and all processing is done locally; no data is sent to servers and designs remain private.
