Hi All,
I've been working through W3 Schools tutorial on jQuery. I worked my way down to the topic on .animate (http://www.w3schools.com/jquery/jquery_animate.asp). For Example 1, of the "Use Queue Functionality", I thought I'd try experimenting with the code, and modified it to add a small red square on top of the large green one (see attached code).
I want the red square to change size as the green square changes size, but maintain its size relative to its larger sibling.
I can make this happen if I 'ID=' each square and give each the appropriate numeric value, but this isn't exactly flexible/generic.
I can use something like '+=100px' and '-=100px', but this clearly adds the same amount to both squares, and naturally the red square doesn't stay relatively sized to the green square.
Using something like '*=2.0' just silently fails.
Anybody have any suggestions?
Thanks,
Richard
