Primer CSS Layout Position

Last Updated : 23 Jun, 2022

Primer CSS is a free open-source CSS framework that is built with the GitHub design system to provide support to the broad spectrum of Github websites. It creates the foundation of the basic style elements such as spacing, typography, and color. This systematic method makes sure that our patterns are steady and interoperable with every other. Its approach to CSS is influenced by object-oriented CSS principles, functional CSS, and BEM architecture. It is a highly reusable model.

In this article, we will learn about the Primer CSS Layout position.

The Position utilities can be used to alter the document flow. The element’s position depends on the content. The element’s final position can be specified by utilizing top-0, right-0, bottom-0, and left-0. The Position can be classified & declared into 5 different categories i.e. relative, absolute, fixed, responsive position, position for screen-reader only, and sticky. The sticky position can further be classified as top, bottom, right & left.

Primer CSS Layout Position Classes:

top-0: This class is used to set the top corner position of the layout.
right-0: This class is used to set the right corner position of the layout.
bottom-0: This class is used to set the bottom corner position of the layout.
left-0: This class is used to set the left corner position of the layout.
position-relative: This class is used to create or set the new stacking context.
position-absolute: This class is used to take elements out of the normal document flow.
position-fixed: This class is used to position an element relative to the viewport.
position-sticky: This class is used to keep an element stuck to an edge as long as its parent is visible.
float-right: This class is used to set the content float to the right.
float-left: This class is used to set the content float to the left.
sr-only: This class can be utilized to position the element that is outside of the viewport.

In order to create the responsive position, we can use the below formula:

position-[breakpoint]-[property]

which will help to implement or change as per the breakpoint in the responsive layouts.

Note: Use combinations of the above classes for fixing your document layout positions as per your need. An example of syntax is given below.

Syntax:

<div class="top-0 left-0 position-absolute">
    ....
</div>

Example 1: The following example demonstrates the top and bottom positions in a default document layout that uses the position-absolute class.

HTML

<!DOCTYPE html> 
<html> 
  
<head> 
    <meta name="viewport" 
          content="width = device-width,  
                   initial-scale = 1"> 
    <link rel="stylesheet" href= 
"https://unpkg.com/@primer/css@16.3.0/dist/primer.css"> 
</head> 
  
<body> 
    <center> 
        <h1 style="color:green;"> 
            GeeksforGeeks 
        </h1> 
        <h3> 
            Primer CSS Layout position 
        </h3> 
          
<p> Notice all the four corners </p> 
  
    </center> 
    <div style="height:100px;"> 
        <div class="position-absolute top-0 left-0">  
            <b>This is top left position</b>  
        </div> 
        <div class="position-absolute top-0 right-0">  
            <b>This is top right position</b>  
        </div> 
        <div class="position-absolute bottom-0 right-0">  
            <b>This is bottom right position</b>  
        </div> 
        <div class="position-absolute bottom-0 left-0">  
            <b>This is bottom left position</b>  
        </div> 
    </div> 
</body> 
</html>

Output:

Example 2: The following code example demonstrates the use of the position-relative class to create a new stacking context.
