Positioning a CSS Pseudo-Element Asterisk Next to Text

Learn how to position a CSS pseudo-element asterisk next to text rather than below it with these simple yet effective techniques.

In web development, styling elements with CSS is essential for an engaging user interface. One of the more refined techniques involves the use of pseudo-elements. Pseudo-elements allow you to style specific parts of an element without altering the HTML structure. A common use-case is adding an asterisk next to form labels to indicate required fields. However, you might encounter an issue where the pseudo-element appears below the text instead of next to it. Let’s explore how to position the pseudo-element asterisk next to the desired text.

Using CSS Pseudo-Elements

Pseudo-elements like ::before and ::after are used to add content before or after the selected elements. Here's a basic example to add an asterisk next to "Option 3":

By adding the ::after pseudo-element, an asterisk (*) will appear after the text "Option 3". However, due to default CSS properties, the asterisk might not be positioned as intended.

Positioning Tricks

Inline Display

To ensure the asterisk appears next to the text, you can use the display property. Setting the display property of the pseudo-element to inline ensures that it falls in line with the text. Here’s how:

Implementing pseudo-elements efficiently can enhance the user experience by making forms and other elements more intuitive, ensuring that indicators like an asterisk are immediately recognizable and properly aligned.
