MobileFrontend currently makes use of text-transform: uppercase on fieldset legends.
That should be seen as non-recommended pattern, as it is
- over-emphasizes legends, they are already carrying bold font styling
- out of touch with other elements on the page,
- it could result in unintended i18n side-effects
We try to keep special font treatment as low as possible, if not clearly stated reasons are given in UI-Standardization.
Moreover such styling should be part of the skin and not of the MobileFrontend extension.
