ABSOULTE POSITIONING:
Removes the element from the document flow and places it relative to the nearest ancestor with a positioning context,eg: relative, absolute, or fixed.
EXAMPLE:
<html>
<head>
<style>
.fixed {
position: fixed;
top: 10px;
right: 10px;
background-color: lightgreen;
padding: 20px;
border: 2px solid black;
}
.content {
height: 1200px;
padding: 10px;
}
</style>
</head>
<body>
<h2>Fixed Positioning Example</h2>
<div class="fixed">Fixed Box</div>
<div class="content">
<p>Scroll down to see that the fixed box stays in place.</p>
<p>This content simulates a long page.</p>
</div>
</body>
</html>
FIXED POSITIONING:
Removes the element from the flow and positions it relative to the viewport. It remains in place even when the page scrolls.
EXAMPLE:
<html>
<head>
<style>
.fixed {
position: fixed;
top: 10px;
right: 10px;
background-color: lightgreen;
padding: 20px;
border: 2px solid black;
}
.content {
height: 1200px;
padding: 10px;
}
</style>
</head>
<body>
<h2>Fixed Positioning Example</h2>
<div class="fixed">Fixed Box</div>
<div class="content">
<p>Scroll down to see that the fixed box stays in place.</p>
<p>This content simulates a long page.</p>
</div>
</body>
</html>
STICKY POSITIONING:
Switches between relative and fixed based on the scroll position.
EXAMPLE:
<html>
<head>
<style>
.sticky {
position: sticky;
top: 0;
background-color: yellow;
padding: 10px;
}
</style>
</head>
<body>
<div class="sticky">I am sticky</div>
<p>Scroll down to see the effect.</p>
<div style="height: 1000px;"></div>
</body>
</html>
