...Explore all our icons at Phosphor Icons Web website. We use a similar approach as many other icon sets out there, providing icons as several webfonts that uses Unicode's Private Use Area character codes to map normally non-rendering characters to icons. Simply add one or more weights by including its stylesheet to the document head, and drop in icons with an i tag and the appropriate classes for the weight and the icon. Phosphor Icons come in 6 weights: regular, thin, light, bold, fill, and duotone. In order to use a weight, you must include a link to its stylesheet, and use the appropriate weight class on the icon (the regular weight uses .ph instead of .ph-regular).
