I've never heard of users editing calendar-view.css, but you might be able to achieve your result by creating a userChrome.css file, of which there are many examples online. If you state exactly what you want to change, someone might be able to advise.

Thank you for your answer. I have a problem with all-day tasks in calendar. It can show only 5 items in one moment (other is hidden), but I have a lot all-day tasks. Where can I find userChrome.css file in my profile? Maybe I can edit it for fix my problem.

Not sure where you see a limit on the number of tasks. Perhaps you could post a screenshot, as I see no limit when tasks are shown in the Today Pane (F11).

The userChrome.css files are user-created. I suggest you do some research on how to make them. A recent example is here.

I mean this area in Week tab. But I guess I know how to fix it, I'll try to modify userChrome.css. Thank you for your help.

I don't know how to change the size of that particular element, but the complete list of all-day events can be shown in the Today Pane, as already mentioned, or in the Find Events pane, under Events & Tasks, by dragging the separator between the pane and the calendar (see picture).
