When learning front-end development, I often needed to run some test code. At the time, I mostly used online tools such as Chinaz's webmaster tools. Now that I have more or less mastered front-end technologies, I decided to build an online tool myself to help more people learn front-end programming more conveniently. Here is a demonstration image of the tool:

Online Running Tool Example

About the LOGO: The current LOGO was designed casually, and it is indeed a bit ugly (haha). Please don't mind it; it will be improved later.

Features of the Online Tool

  1. Responsive Design
    The front end uses the Bootstrap framework, allowing the page to display properly on mobile phones, tablets, and computers.
  2. Real-Time Code Execution
    A modern framework is used to run code, so there is no need to refresh the page and navigate away as with traditional tools.
  3. Code Syntax Highlighting
    By integrating syntax highlighting, learning and debugging become more convenient.
  4. Error Notifications
    Real-time code error notifications are provided to help users quickly locate and fix problems.

Styles and Technology Stack

  • The page styles primarily use the Bootstrap framework, which is simple and easy to extend.
  • Syntax highlighting is supported for code in multiple languages (HTML, CSS, and JavaScript).
  • The error detection feature integrates a simple and effective error reporting module.

The features and interface will continue to be optimized in the future. Suggestions and feedback are welcome~
