Sure! Here's an example of an HTML file containing a 30-second timer that can be changed dynamically using JavaScript:

30-Second Timer

30 seconds

To use the timer, simply save the above code in a file with the `.html` extension and open it in a web browser. You will see the timer displayed as "30 seconds" with an input field to change the timer duration. Click the "Start" button to start the timer, and you can click the "Reset" button to reset it back to the original value. Feel free to customize the code and styling according to your preferences.
