JavaScript

variable value and css property

Hi friends. I am having a problem with this: all the code is going to be on a click function .

  var sectionWidth = $(".container-section").width();   
  $(".container-section").animate({
    right: "+=-42%" 
  }, 1000);

Everything works fine, however on line 4 I want to keep the +=- and only replace the 42% with the value of de variable "sectionWidth" in px. I tried but i cant get it to work. thx in advanced.

Have you tried closing the quotations around +=- and then placing your variable?

Something like:

right: "+=-"+sectionWidth;

Thx mate! I was loosing my mind. This works perfectly.

No problem!
