- Web front-end OpenType font feature management: Adding and enabling deep parsing
- This article explores the possibilities and limitations of managing OpenType font features in HTML/CSS. The core conclusion is that OpenType features such as kerning kern cannot be added directly to font files through HTML, CSS, or standard JavaScript APIs. These features must be pre-embedded in the font itself, and the font-feature-settings property of CSS is only used to enable or disable features already in fonts. The article will explain this mechanism in detail and provide control methods for existing features. At the same time, it emphasizes the complexity and inrecommendability of dynamically modifying font files on the client. It is recommended to solve the problem of missing font features from the source.
