Primer CSS Popover Right-top

Introduction

Primer CSS Popover Right-top is a user interface component that shows additional content related to an element when it is clicked or hovered. It is a part of Primer CSS, a CSS toolkit and design system created by GitHub.

The Right-top part of the name indicates that this popover component is positioned on the right side of the triggering element and aligned to the top of it.

Usage

To use Primer CSS Popover Right-top, you need to include the Primer CSS stylesheet and the JavaScript library that powers the popover functionality. You can find detailed instructions on how to install and use Primer CSS on the official Primer CSS documentation page.

Once you have included the required files, you can add the Popover HTML attribute to any element to make it trigger the popover functionality. You can also customize the content of the popover, its position, and its appearance using various options and classes.

Here is an example of how to create a simple popover with a custom title and some text content:

<button class="Popover" aria-label="Click me" data-popover-content="popover-content-1" data-ga-click="Popover, open, click">
  Click me
</button>

<div id="popover-content-1" class="Popover-message">
  <h3 class="Popover-title">Hello World</h3>
  <p>This is a simple popover created with Primer CSS. You can customize the content and appearance of popovers using various options and classes.</p>
</div>

In this example, we have a button element with the Popover attribute that triggers a popover with the ID popover-content-1. The content of the popover is a <div> element with the Popover-message class that contains a title and some text. The data-ga-click attribute is optional and is used to track interactions with the popover using Google Analytics.
