Hello,
#1
It is not possible to move the position of the input box from String Widget input as there is no configuration for it. It may be possible to submit a Feature Request to support@knime.com if you would like to request it.

It is difficult to answer without knowing if you are using the legacy widget or the new widget UI. Custom CSS only works in legacy mode, so none of the css would be applied if it wasn’t using that mode.
(In 4.3 and beyond it’s off by default, so CSS is not supported by default because we have the new styles.)
Just to be clear - this is just in regards to Widget styling with CSS. The CSS editor still works the same for JS view nodes.

Please let us know if you have any further questions.
Thank you,
