I want to slow down animation timing in .opacity CSS property.
Like, i want it to delay 0.2ms or something like that.
To get a better idea, opacity is added when hovered a featured post on my site here: http://www.thetechnodaily.com
Remember: I have NOT USED jQuery in this. Its pure CSS.
What you seem to be looking for is CSS Transitions.
Transitions allow you to set a delay and the length of the transition.
