Ligatures are typographic elements that combine two or more letters into a single glyph, improving the visual appeal and readability of text. Common examples include letter pairs like "fi," "fl," and "tt," which can appear cramped when typed separately. Using ligatures can enhance the overall design by refining spacing and rhythm, making typography feel more polished. The article details how to implement ligatures in various design software, including Adobe InDesign, Photoshop, Illustrator, Figma, and Microsoft Office applications. In Adobe software, ligatures can be enabled through the OpenType menu in the Character panel. For instance, in InDesign, users can select the text, access the OpenType menu, and activate either standard or discretionary ligatures. Figma allows users to toggle ligatures in the Typography section of the right sidebar, while Microsoft Word has a more limited implementation, requiring users to navigate through the Font dialog box. PowerPoint and Excel lack robust support for OpenType features, leading to suggested workarounds like copying text from Word to preserve ligatures. The article also offers guidance on implementing ligatures in CSS, emphasizing the use of `font-variant-ligatures` for common ligatures and `font-feature-settings` for more specific controls. Users can enable or disable ligatures directly in their style sheets, allowing for greater flexibility in web design. While ligatures can significantly enhance legibility and aesthetic appeal, the article warns against overuse, particularly with discretionary ligatures, which may lead to overly ornate text.
