Hi

Title says it all - CSS is affecting my entire site not just the video I have tried to target.
I am using Classify plugin.

Here is a screen shot of the CSS I have used -

May be better to give the video tag in your element an id attribute and then instead of using ‘video’ in the script tags use the element’s id like ‘#elementID’

Thank you, I’ll give this a shot.
I appreciate your help!
