Parameters Default Values are wrong #6

Describe the bug
The progress bar on the website https://progress-bars-eight.vercel.app/bar?progress=75 does not have default width and height values. By default, both the width and height are set to 0, making the progress bar invisible. It should default to 200px width and 20px height.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'https://progress-bars-eight.vercel.app/bar?progress=75'
2. Observe that the progress bar has no visible size (width and height are 0).
3. See that the progress bar does not display as expected.

Expected behavior
The progress bar should default to a width of 200px and a height of 20px if no other width and height parameters are provided.

Additional context
Other parameters might also have incorrect default values, but the main issue is with the default width and height being 0.
