Refactor HTMLFormatter for improved readability and style consistency

- Corrected string formatting for CSS styles in HTML output
- Simplified inline space handling logic in bullet lists
- Added flake8 noqa comments to suppress style warnings for CSS syntax

These changes enhance the maintainability of the HTML formatter without altering its functionality.
