I need to resize an embedded youtube video that is taken form a view. The video shows up to big and doesn't fit into the block it is assigned to, making the video to big. Is there anyways I can resize the video through the block, or through the view?

I have a custom content.
It has a field called "Unique Card" which is a Boolean.
It is either "1" (unique) or "0" (not unique).
I'm editing my node tpl for that node type.

node--netrunner-card.tpl.php

What I need to do is... if the 'Unique Card' field is "1" then I need to put an asterisk in front of $title wherever it displays.

I have a site with a calendar that indicates when a house is rented or free. This is simply indicated be coloring the day if there is made ​​a reservation for that day.
That day is also a link to more details of this reservation and I do not want other people to see the content of this information. How do I make sure that there is no link shown for that day in the caldendar and the day in the calendar is only colored?
With CSS, this is not possible as far as I know ...
