-

this question has answer here:

i find when position element fixed, doesn't matter if parent positioned relative or not, position fixed, relative window?

css

#wrapper { width: 300px; background: orange; margin: 0 auto; position: relative; } #feedback { position: fixed; right: 0; top: 120px; }

html

<div id="wrapper">     ...     <a id="feedback" href="#">feedback</a> </div>

let me provide answers both possible questions. note existing title (and original post) ask question different seek in edit , subsequent comment.

to position element "fixed" relative parent element, want position:absolute on child element, , position mode other default or static on parent element.

for example:

#parentdiv { position:relative; } #childdiv { position:absolute; left:50px; top:20px; }

this position childdiv element 50 pixels left , 20 pixels down relative parentdiv's position.

to position element "fixed" relative window, want position:fixed, , can use top:, left:, right:, , bottom: position see fit.

for example:

#yourdiv { position:fixed; bottom:40px; right:40px; }

this position yourdiv fixed relative web browser window, 40 pixels bottom edge , 40 pixels right edge.
