Support for 3 digit number of days without line break

[OffCrazyFreak]

When there are more than 100 days in the counter the flipdown automatically line-breaks to make it's width 510px as set in css file.

More than 100 days until something happens is not uncommon and it would be nice if the default css supported it.

By removing width: 510px; from the css file the flipdown takes up full width.
The problem then appears that the media query is activating too late so the flipdown is line breaking once again.

By increasing the media query to max-width: 570px resizes the flipdown to the smaller size, but here we come across the same problem as before - fixed width so the flipdown is line-breaking automatically although it has space to take up.

By removing width: 312px; from the css file the flipdown once again takes up full width.

I will make a PR with these changes for you to check out.
