Outline fonts are fonts that consist of only the outlines of each character, without any fill or shading inside. They are often used for display purposes, such as headlines, titles, and logos, as they can make a bold and eye-catching statement. Outline fonts come in a variety of styles, from simple and geometric designs to more ornate and decorative options. They can also be used in combination with other fonts to create interesting text effects. Outline fonts are often used in digital designs, such as websites and social media posts, as well as in print materials, such as brochures, posters, and flyers. They are a popular choice for designers who want to add a modern and minimalist touch to their projects.
