How to run two jQuery animations simultaneously

Question

Is it possible to run two animations on two different elements simultaneously  I need the opposite of this question Jquery queueing animations   I need to do something like this         first   animate   width  200    200       second   animate   width  600    200     but to run those two at the same time  The only thing I could think of would be using setTimeout once for each animation  but I don t think it is the best solution

I believe I found the solution in the jQuery documentation:

Animates all paragraph to a left style of 50 and opacity of 1 (opaque, visible), completing the animation within 500 milliseconds. It also will do it outside the queue, meaning it will automatically start without waiting for its turn.
$( "p" ).animate({
  left: "50px", opacity: 1
}, { duration: 500, queue: false }); 

simply add: queue: false.

That would run simultaneously yes  what if you wanted to run two animations on the same element simultaneously      function              first   animate   width   200px     200           first   animate   marginTop   50px     200         This ends up queuing the animations  to get to run them simultaneously you would use only one line     function              first   animate   width   200px   marginTop  50px     200         Is there any other way to run two different animation on the same element simultaneously

See this brilliant blog post about animating values in objects   you can then use the values to animate whatever you like  100  simultaneously   http   www josscrowcroft com 2011 code jquery-animate-increment-decrement-numeric-text-elements-value   I ve used it like this to slide in out           slide   function id  prop  from  to                if  from  lt  to                       Sliding out                 var fromvals     add  from  subtract  0                    var tovals     add  to  subtract  0                  else                      Sliding back in                 var fromvals     add  from  subtract  to                    var tovals     add  from  subtract  from                                 fromvals  animate tovals                    duration  200                  easing   swing      can be anything                 step  function         called on every step                        Slide using the entire -ms-grid-columns setting                       id  css prop   this add - this subtract     px 1 5fr 0 3fr 8fr 3fr 5fr 0 5fr

While it s true that consecutive calls to animate will give the appearance they are running at the same time  the underlying truth is they re distinct animations running very close to parallel   To insure the animations are indeed running at the same time use     function             first   animate       queue   my-animation             second   animate       queue   my-animation    dequeue  my-animation          Further animations can be added to the  my-animation  queue and all can be initiated provided the last animation dequeue s them   Cheers  Anthony
