Shadow font is a type of font that features a shadow effect to give the letters and characters a three-dimensional appearance. The font appears as if it has a shadow cast behind it, which can be seen as a darker outline or background behind the letters. This effect can add depth and dimension to the font, making it stand out and look more visually appealing. Shadow fonts are commonly used in graphic design, advertising, and other applications where the text needs to grab the viewer's attention. They are often paired with bold and bright colors to create eye-catching designs.
