Question

I have this effect $("#stage").effect("pulsate", { times: 1 }, 700);

But there are no configuration settings that I can use.
For example the Pulsate effect will bring the opacity down to 0% and then back up to 100%.
What can be done so that the opacity will go down to 70% instead of 0%?

Answer 1

The API does not specify any way to do it.
I would recommend using animate() to do the single pulse.
Remember that animations are queued, so you could do like this:

$("#stage").animate({opacity : 0.7}).animate({opacity : 1})
