Announcements are not easily seen. Please fix for the next release

I have tried using the "Announcement", and even set the font size to really large and change the colour to RED. However once saved and published, it just appears as small black text. Which isn't an announcement, more of a whisper.

How do I get it to display as intended ?

Also, I have see that I can set the From and To date for the announcement to displayed, It seems that I can select the same date on both but the time difference is only 1minute. or I can set the dates to be a 24hr period. Again very limiting, so how do I change the time frame?

Lastly, when we upgrade SDP, it would be useful if the default webpage was able to display the "Announcement" i.e SDP is currently undergoing maintenance and will be available again at 2pm. Does SDP allow for such functionality, or do the users simple get a unhelpful error when system is undergoing maintenance?

Thanks
