Python Development Techdegree Graduate 33,620 PointsThe transition-property was not defined anywhere in the css?
I thought when we we want an element to receive a transition effect, the 'transition-property' property must be defined in the target element we want to apply it to. However I don't see any transition-property in the main.css file.
Can anyone please clear my doubt in this part? Thank you

Python Development Techdegree Graduate 33,620 PointsBut the transition styling for the background-color transition was written under the .css file though. Am I missing something here? Or are you saying that the transition-property was wrriten in the .js file?

231,236 PointsThe transition-property CSS value would be used for CSS transitions. But JavaScript/animsition provides a different way of creating effects that does not require or use that property.

Python Development Techdegree Graduate 33,620 PointsI see. So I can assume that the other 'transition' property in other element selected in the .css file is also done using Javascript since there is no 'transition-property' being declared anywhere in the code.

231,236 PointsWithout seeing the actual code you are referring to, it's a bit of a guess. But it seems likely, and particulary since this is a course about jQuery plug-ins.

4,590 PointsHi Steven,
I'm confused with this problem too. Why does transition effects done using JS? And what is the different between transitions and transition effects?
Thank you

231,236 PointsCSS transitions are "transition effects". All that means is that you will see things changing on the screen.
The transition effects are being done in JS here because this is a course on jQuery plugins. In actual practice, I would generally recommend using CSS transitions instead when possible. But not every kind of effect can be done in CSS, so sometimes you can only do what you want by using JS.
