Setting the style zIndex property has no effect on non-positioned elements  that is  the element must be either absolutely positioned  relatively positioned  or fixed   So I would try     this  parent   css  position    relative      this  parent   css  z-index   3000

That s invalid Javascript syntax  a property name cannot have a -   Use either zIndex or  z-index

zIndex is part of javaScript notation  camelCase  but jQuery css uses same as CSS syntax   so it is z-index   you forgot  css  attr   value    use   or   in both  attr and val  so    css  z-index   3000
