I have tested this item ✅ successfully on 7321f25
I have tested this fix on my local Joomla installation.
Testing Environment:
- Joomla Version: 6.1.0-alpha1-dev (or your version)
- PHP Version: 8.4 (or your version)
- OS: Windows 10/11
- Server: XAMPP
Testing Steps:
- Applied the patch to templates/cassiopeia_extended/templateDetails.xml
- Cleared Joomla cache
- Verified that the font size fields now have
min="0"andstep="0.1"attributes - Attempted to enter negative values (-999) in the Body Font Size field
- Browser correctly prevented negative input
Result: ✅ The validation works perfectly. Negative font sizes are now blocked, preventing the layout breakage issue.
This fix should be merged.
