Understanding ::before and ::after Pseudo-Elements in CSS
The ::before and ::after pseudo-elements in CSS allow you to insert content before or after an element's actual content without modifying the HTML structure.
::beforeinserts content before the element's content.::afterinserts content after the element's content.Both pseudo-elements require the
contentproperty to display anything.They are often used for decorative purposes, icons, or additional styling cues.
In this example, ::before adds a star before the paragraph text, and ::after adds sparkles after the text. The original HTML remains unchanged.
Always use the
contentproperty when using::beforeor::after.Use these pseudo-elements for decoration or styling, not for essential content.
Combine with other CSS properties like
color,font-size, andbackgroundfor visual effects.Test across browsers to ensure consistent display.
