- Manage OpenType font features in HTML/CSS: Feasibility and Limit Deep Analysis
- This article discusses the feasibility and limitations of "adding" OpenType font features in HTML/CSS.

The article emphasizes the importance of understanding the principles of font design and recommends that you communicate directly with the font designer when font characteristics improvements are needed instead of trying complex client file operations.
