Fixed position but relative to container

Question

I am trying to fix a div so it always sticks to the top of the screen, using:

position: fixed;
top: 0px;
right: 0px;

However,

Answer 1

/* html */

/* this div exists purely for the purpose of positioning the fixed div it contains */


     

          my fixed content
     





/* css */

/* wraps fixed div to get desired fixed outcome */
.fix-my-fixed-div-to-its-parent-not-the-body 
{
    float: right;
}

.im-fixed-within-my-container-div-zone
{
    position: fixed;
    transform: translate(-100%);
}
