A Mobile-Friendly HTML Code Editor and Preview Tool

Use Cases#

Anyone who has used DeepSeek knows that HTML code generated by DeepSeek can run directly on a computer without extra steps.

However, it cannot run on mobile devices.

This means that without a computer nearby, you cannot write code and debug it on your phone—quite inconvenient.

To solve this, I used DeepSeek to create a small tool that took just 5 minutes to develop. You can run HTML code directly on your phone. It’s incredibly simple—just open it in your browser.

Of course, you can also deploy this tool on your own server and access it anytime, anywhere!

Development Steps#

1
Write me a complete HTML page.
2
Features:
3
1. An unlimited-length text input where users can enter HTML code (including CSS and JavaScript)
4
2. Two buttons below the input: "Run" and "Clear"
5
When clicking Run, execute the code in the input as HTML in the browser and display the result.
6
When clicking Clear, empty the input.
7
3. Style the entire interface following Linear app's design aesthetic with polished styling for each element.

The "Run" button doesn't respond. Please regenerate with complete code.
