1
00:00:00,550 --> 00:00:04,270
We can easily add additional parameters to the estimate method.

2
00:00:04,450 --> 00:00:10,510
Say we wanted to not only estimate the position but also the opacity and toggle the height of the element

3
00:00:11,550 --> 00:00:13,500
we can do that by adding a comma

4
00:00:16,200 --> 00:00:19,920
and inserting the new parameters will start with opacity

5
00:00:26,440 --> 00:00:35,270
next will toggle the height.

6
00:00:35,290 --> 00:00:38,610
Now when we save our file and previewed in the web browser

7
00:00:43,940 --> 00:00:45,470
we can see that the opacity

8
00:00:49,310 --> 00:00:55,100
reduces to zero and the height is also toggled to zero as well.
