You can style these icons with CSS properties like
color,font-size,margin, andposition.Perfect for adding decorative symbols, social media icons, or arrows without extra markup.
In this example, the ::before pseudo-element inserts a gold star before the paragraph text. No additional HTML elements are needed to display the icon.
