Denis refined the typography for the workspaceAdmin theme in the VKCOM/vkui-tokens repository, focusing on improving readability and visual hierarchy. He adjusted the headline3 token, reducing the font size from 15px to 13px and the line height from 20px to 16px. This change was carefully implemented across cssVars, pixelify, pseudo, and root layers to ensure consistent styling throughout the theme. Using CSS and front-end development skills with JavaScript and TypeScript, Denis addressed a specific design need with a targeted, traceable update. The work demonstrates attention to cross-layer consistency and a methodical approach to UI and theme development.
