How to prevent other elements changing, when changing style of element with same class

I am moving individual elements around using their style.top and style.left attributes. The issue is that when changing the style of one element it seems to change the style of others. What is an effective w开发者_StackOverflow中文版ay to get round this?

I'm not sure why this happens, but I guess you selected the element by using a .class selector. Please make sure to select only one element. If you add / edit style-rules of that element, it does not change other elements sharing the element's classname.
