html css make elements still make room for position fixed element code example

Example 1: avoid div slider stack on each other when position absolute

//avoid slides in slider stack on each other when position:absolute in responsive mode
//use 'vw'(automatically responsive) instead of 'px'(will stretch the elements when page responsive)
//each card width:
cards.forEach((card, index) => card.style.left = index * 90 + 'vw');

Example 2: fixed within the div css

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

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