How to Relatively Position an Element without It Taking Space in the Document Flow?
In standard CSS positioning, relatively positioned elements occupy space within the normal document flow even after being offset by top, left, right, or bottom properties. This can create a gap in the layout where the element would have naturally sat, disrupting the alignment or layout of other elements around it. In this article we will position an element so that it appears relatively within the document but does not affect the design of surrounding elements, effectively making it "overlay" without creating extra space.
Relatively Position an Element without It Taking Space
- Use a combination of CSS positioning techniques to remove elements from normal document flow while allowing it to be positioned relatively.
- Specifically leverage absolute positioning within a relatively positioned container, setting position: relative; to the parent element and position: absolute; on a child element.
This method allows the element to be positioned according to the boundaries of its nearest positioned ancestor (i.e., the relatively positioned parent element) without taking up any space in the document flow.
Follow the Steps to Relatively Position an Element
- Step 1: Define a parent container with position: relative; so that it establishes a positioning context for child elements.
- Step 2: Set the child element to position: absolute; to remove it from document flow and allow precise control over its position.
- Step 3: Use top, left, right, or bottom values on the child element to set its position within parent container.
Example Code
In this example, we create a div container with position: relative; but set its width and height to zero. This way, it does not take up any visible space in the document. Inside this container, we have a child element with position: absolute; and specified offsets (top and left) to control its position relative to where the parent would be.

</div>
<p>
This is some text below the positioned element.
The element above is offset without affecting this text,
showing that it does not take any space in the document flow.
</p>
</body>
</html>
Output
Explanation
- Parent Element: The outer div has position: relative; but a width and height of zero, making it invisible while serving as a reference point for positioning the child element.
- Child Element: The inner div is position: absolute; with left: 100px; and top: 100px;, positioning it 100 pixels down and to the right within the parent. The content inside reads: "Tutorials Point: Your go-to resource for quality tutorials on programming, technology, and more!"
