Mike is concerned that there are some aspects of the look and feel which don't reflect his expectations. Despite it being a prototype, he is insistent that these be addressed.

He would ideally like the text to be in the 'Helvetica' font, but understands that cannot be guaranteed. Failing that he would like 'Arial', but if that is not possible, he wants to be sure that the font is from an appropriate generic family.

Modify one place in the CSS to use an appropriate font for the page text $($note that text in the input fields and the buttons may not be changed$).$

Some elements are to be changed to less intense background colours. Mike isn't specific about the exact colour, so anything meeting his specifications will be fine.

The elements you need to change are:

text inputs to have a pale green background

valid feedback to be shown as bold black text on a yellow background

invalid feedback to be shown as bold black text on a red background.

Change the text and background colours and text formatting as required. You may use any CSS mechanism to specify the colour. Note that autocomplete features in your web browser may affect the background colour of some inputs $-$ you are not required to address this.
