django - Why is the size of fonts from production css different from development when using same css in browser? -

I have correct.py my setup.py so that my lighttpd server can use static files for production. The output page is called CSS correctly, but my problem is that these sizes are very different from the pages of development despite the same CSS file.

When I look at the source code from the browser, it happens that the CSS source for production in the browser window looks shorter than the CSS source for the development. What could possibly be the reason for this?

View source CSS does not apply.
