Free CSS & HTML Widget Previewer - Design Widgets Live Online

The Qurkx Widget Previewer is a powerful, free online tool designed for bloggers and web developers to design, test, and preview CSS and HTML widgets in real-time. Our live canvas environment lets you write code on the left and instantly see the rendered output on the right, making it the perfect sandbox for creating custom Blogger widgets, CSS animations, and HTML components.

What is a Widget Previewer?

A widget previewer is an interactive development environment that allows you to write HTML and CSS code and immediately see how it looks when rendered in a browser. Unlike traditional code editors where you have to save and refresh, our tool provides instant visual feedback, helping you iterate faster and design better widgets for your blog or website.

How to Use the Widget Previewer

1. Write Your Code: In the left panel, paste or write your HTML and CSS code. You can include complete HTML documents or just widget snippets.
2. Live Preview: Watch the right panel automatically update as you type. The preview refreshes every 400ms for smooth, real-time feedback.
3. Tab Indentation: Press the Tab key to insert proper indentation (2 spaces) for clean, readable code.
4. Auto-Save: Your work is automatically saved to your browser's local storage, so you won't lose your progress if you accidentally close the tab.
5. Copy & Use: Once you're happy with your widget, copy the code and paste it into your Blogger template, post, or website.
