Problem Statement:
Creating 3D-like buttons with pseudo elements and filter gradients in IE8.
Main Question:
Why don't filters work on pseudo elements in IE8?
Background Information:
- Using conditional comments to handle different browser versions.
- IE8 does not support filter gradients on pseudo elements.
Updated Problem Statement:
Filters are not applied to CSS-generated content, despite not being explicitly mentioned in MSDN documentation.
Solution in IE8:
Apply filters to conditional elements as done for IE7.
Remaining Question:
Why do filters specifically not work on pseudo elements in IE8?
Possible Answer:
- Gradient filters are "procedural surfaces" that require an object containing content.
- Pseudo elements generate content, not objects containing content.
- Therefore, there is no suitable object between which to apply the filter.
