Can CSS Force Anti-Aliasing? Unveiling the Myth

Question:

A client has expressed concerns regarding the appearance of a system font in IE6, which lacks support for anti-aliasing. Can CSS resolve this issue using the "pt" unit instead of "px"?

Answer:

Yes, anti-aliasing can indeed be enforced using CSS, but utilizing the "pt" unit alone will not achieve this effect.

Instead, the following CSS properties can be employed:

• -webkit-font-smoothing: antialiased;
• -moz-osx-font-smoothing: grayscale;
• font-smoothing: antialiased;

Note: These properties are not supported by all browsers. However, for Firefox, an additional setting is required:

• font-feature-settings: "kern"

Additional Information:

While using "pt" may slightly improve font rendering in some situations, it does not guarantee anti-aliasing. The aforementioned CSS properties are more effective in enforcing anti-aliasing and improving text clarity.
