Used flexbox and dataset

Found it hard to get the radial gradient of the box component right and the position of the child elements of the box.

Still unsure whether the component box gradient and spacing between the child elements is correct. For the submit button when viewed on mobile viewport, there's a white or grey outline that randomly appears which I'm not sure what it is.

Are there more efficient ways of centering text in divs? Additonally is there anything I should do to the component box radial gradient to make it look more accurate as it looks a little off?
