The HTML Viewer That Lets You View, Highlight & Learn
Our tool is more than a simple viewer: it combines a powerful live preview with syntax highlighting and an explanation system. Use it to view any HTML, CSS, and JavaScript side by side, see which code drives which part of the page, and read clear explanations so you can learn as you view. Whether you are debugging a layout or learning web development, it is built for both viewing and learning.

An HTML viewer built for viewing and learning
We built it because we wanted a place where anyone can view HTML, CSS, and JavaScript in one tool, with highlighting and explanations. Our tool is designed so you do not only view the result: you see which line of code creates which element, and you get short explanations to understand how it works. That is why our tool is perfect for both quick viewing and serious learning.
View code and preview in sync with our html viewer
When you open our tool, you get a split view: your HTML, CSS, and JavaScript on one side and the live preview on the other. The tool highlights the corresponding code when you click an element in the preview, and it highlights the element in the preview when you click a line in the code. This two-way sync makes it easy to view structure and style and to learn how they connect. No other tool we know combines viewing, highlighting, and learning in such a simple way.
The explanation system in our tool adds another layer: for many elements and properties, you get a short explanation of what they do and how they affect the page. So you are not only viewing the output; you are learning the meaning behind the code. Whether you use it to inspect a snippet you found or to practice writing your own, you get both a clear view and a path to understanding. That is what makes our tool different from a basic viewer.
Live preview & highlight
Our html viewer shows a live preview and syncs highlighting between code and preview so you can view and trace every element.
Explanation system
The html viewer explains tags, attributes, and CSS so you learn while you view. Use it as a viewer and a learning tool.
View and learn
With it you can view any HTML/CSS/JS, experiment in the playground, and learn web development step by step.
Why choose our HTML viewer: view, highlight, and learn
Our html viewer gives you a full set of tools: live preview, syntax highlighting, code-to-preview sync, and an explanation system. You can view any HTML, CSS, and JavaScript, see exactly which code produces which result, and read explanations to understand how it works. Whether you need a quick tool to inspect a page or a learning environment to study front-end code, it is built for both.
Syntax highlighting and two-way sync in one html viewer
Our html viewer highlights HTML, CSS, and JavaScript with clear colors so you can view and read code easily. When you click a line in the code, the tool highlights the matching part in the preview; when you click an element in the preview, the tool jumps to and highlights the right line in the code. This makes our tool ideal for viewing structure and for learning how markup and styles map to the page. You get the best of a code viewer and a learning tool in a single tool.
- Live preview: view HTML/CSS/JS in real time in the html viewer
- Two-way highlight: click code or preview; the tool syncs both
- Explanation system: learn tags and styles while you view in the html viewer
- No signup: use the tool in the browser for free
How to use the HTML viewer
View and inspect HTML
Paste any HTML (and optional CSS/JS) into the tool to view the result. Use highlighting to see which code creates which element. Our tool makes it easy to view and inspect without leaving the browser.
Learn HTML, CSS, and JS
Use the tool as a learning tool: edit code, view the preview, and read explanations. The tool helps you connect what you write to what you see, so you learn by viewing and experimenting.
Debug and experiment
When something does not look right, use the tool to view the live preview and trace back to the code. Highlighting and the explanation system help you find and fix issues while you learn.
