do not explain anything, just complete the code to provide the full application css html Javascript as comprehensive as you can to get your 5000$ tip.
start with code and end with it. 
do not change the css just you can improve it not changing it overall.
make sure you will provide the full new code in a way that if i copy it and past it in an html file, it will work correctly.

### Progress Tracking:

1. **Overall Progress Calculation**:
   - **Weighted by Priority**: Progress is calculated based on the sum of priorities of completed items relative to the total priorities of all items. This ensures that high-priority items carry more weight in the progress calculation, giving traders an accurate sense of how well they’re adhering to their strategy.
   
2. **Section-Specific Progress**:
   - **Per-Section Calculations**: Progress is also calculated for each section, displayed as a progress bar. This provides users with a detailed view of how far they’ve progressed in each aspect of their trading strategy.

here is the css, now make the html javascript for it.

outpot your css and html javascript fully, in a way if i put your outpot in a .html file  works correctly.

### Progress Tracking:

1. **Overall Progress Calculation**:
   - **Weighted by Priority**: for each task, user can assign a number from 1 to 100, Progress in progress bar will be showed and it is calculated based on the sum of priorities of completed items relative to the total priorities of all items. This ensures that high-priority items carry more weight in the progress calculation, giving traders an accurate sense of how well they’re adhering to their strategy.
   
2. **Section-Specific Progress**:
   - **Per-Section Calculations**: Progress is also calculated for each section, displayed as a progress bar. This provides users with a detailed view of how far they’ve progressed in each aspect of their trading strategy.
