Definition of CSS Position

The CSS Position property defines the positioning of a specific element on a web page. This article’s main importance is showing how to control the position part and display of the content. Doing Positioning with the old CSS version is quite complicated. Therefore, a new standard CSS flexible Layout has more recent versions. Coming to the positioning and layout model is difficult as they have to cope with browser implementation issues. This positioning property has five methods: static, relative, absolute, sticky, and fixed.

Syntax Relative:

Position:relative; Top:10px; Right:25px;

Syntax Absolute:

Position:absolute; Top:12px; Right:23px;

This action is based on the parent element, positioning the element precisely at the specified location.

Syntax Static:

Position:static; display:inline; Display:inline-block float:left; clear:both; overflow:hidden; How Does CSS Position Work?

This property aids in calculating the layout and content specified on websites.

There are four sets of properties for positioning:

Property 1: Left, Right, Top, Bottom (This implies the distance of an element from the edge corner of the viewport).

Property 2: The positioning concepts.

Property 3: Z-Index.

Property 4: Formatting style.

Here are some CSS positions, along with a brief explanation of how they work:

1. Static

Static-positioned elements are set as the default and have no impact on right, left, bottom, or top properties. They don’t have any special direction. It was made positioned on the normal Page.

2. Relative

It is helpful while creating a CSS layout, and it finds quite difficult. An HTML element with this property works the same as a static, and they differed by setting the right and left values to the ancestor element.

3. Fixed

Fixed positions are similar to absolute positioning, but they break away from the normal flow of the text and remain fixed at a specific point on the web page. All other HTML elements behave as if the fixed position element does not exist on the page. The key difference between absolute positioning and fixed positioning is a fixed position will retain its space on the ongoing page when there happens to have some page Scroll.

4. Absolute

In this position, an element places itself with respect to itself and excludes itself from the document’s normal flow. Generally, they position themselves in the top-left of their ancestor or parent element.

5. Z-Index

A scenario arises where the elements on the web page overlap in the normal flow. The Z-index property is used to position those elements on the top or bottom. In layman’s words, it determines the stacking order of an element or might be referred to as a three-dimensional viewport. The positive margin indicates that an element should be pushed to the top, whereas the negative margin indicates that it should be pushed to the bottom. And the Z-index does not work well with static positioning concepts.

Examples to Implement CSS Position

Here are different examples of CSS positions:

Examples #1: Using Static Position

This is the example of CSS static position as follows.

Code:

.box{ color: #fff; background: #73AD21; padding: 5px; } .container{ padding: 50px; margin: 50px; position: relative; border: 5px dotted; font-family: Arial, sans-serif; } .container p{ line-height: 40px; }

Output:

Examples #2: Using Relative Positioning

This is the example of the CSS relative position as follows.

Code:

.box{ position: relative; left: 50px; color: #fff; background: yellow; padding: 15px; } .container{ padding: 45px; margin: 45px; border: 4px solid black; font-family: italic, sans-serif; } .container p{ line-height: 40px; }

Below Output creates a CSS border and notes that an element can be moved in a layout.

Output:

Examples #3: Using Fixed Positioning

This example demonstrates the CSS fixed position.

Code:

.box{ position: fixed; top: 100px; left: 150px; color: #cce; width: 50%; background: #efefef; padding: 20px; } .container{ padding:40px; margin: 40px; position: relative; border: 4px solid black; font-family: calibri, sans-serif; } .container p{ line-height: 60px; }

Output:

Examples #4: Using Absolute Positioning

Code:

.box-green { position: absolute; background: green; width: 90px; height: 95px; left: 6px; top: 8px; }

The following output displays an element positioned at the beginning of its parent.

Output:

Examples #5: Demo Using all Three Positioning

This is an example of the CSS’s positions using relative, static, and absolute.

Code: chúng tôi

Code: new.css

body { border: 2px solid black; } section { border: 1px solid black; margin: 1rem; position: relative; } div { background: linear-gradient(to bottom, blue, white); border: 2px dashed black; height: 26px; margin: inherit; width: 80px; top: 81px; left: 71px; } .relative { background: linear-gradient (50deg, black, white); position: relative; } .absolute { background: red; position: absolute; } .fixed { background: yellow; position: fixed; }

Output:

Conclusion

Therefore, we have seen how to use CSS to specify the position of an element. Anyone can learn these concepts with a basic knowledge of HTML and CSS. Generally speaking, HTML elements are visible, like the direct order structure, to disturb the normal flow or overlap the elements for a better page Layout; CSS can be used.
