checkboxes and radio buttons weirdly rendered in browser Safari

[fvitalini]

The check boxes and the radio buttons in SmaRP are not rendered properly if using Safari as a browser.

Chrome seems to ignore the css specification border: 10px solid red; under /* vertical radio/checkbox alignment to text */, whereas Safari pics the option. This seems anyway unwanted and should be removed.

@fvitalini, I have no idea why I left such CSS style border: 10px solid red, probably it was an interim way to double-check the alignment but it was definitely not meant to be committed. Thanks for spotting!

The line can and should be removed.
