The recommendation above goes against the official TemplaVoila recommendations. It will not work if there many different templates for the same data source. When template is changed, that TS will have to be updated too. If CSS is mapped as header parts, TV takes care about it.

The issue with conditional comments in TV is fixed by Steffen Kamper and will appear in the next TV version.
