The colors used in the form are predefined as $color-red: #AE1100, $color-bg: #EBECF0, $color-shadow: #BABECC, and $color-white: #FFF. The form is given a background color of $color-bg. The body, p, input, select, text area, and button sections are given the styles of font-family as 'Montserrat', sans-serif, letter-spacing as -0.2px, and font-size as 16px. The button is given a font size and a padding of 16px, and a background color as $color-bg, and a text shadow as 1px 1px 0 $color-white. The input fields are given a box-shadow as inset 2px 2px 5px $color-shadow, inset -5px -5px 10px $color-white, and a transition value as all 0.2s ease-in-out. In a focus event, the box-shadow of the input fields turns to inset 1px 1px 2px $color-shadow, inset -1px -1px 2px $color-white. The button is given a cursor style as pointer to get the hand cursor effect, font-weight as 600, color as #61677C, transition as all 0.2s ease-in-out, and box-shadow as -5px -5px 20px $color-white, 5px 5px 20px $color-shadow, which changes to -2px -2px 5px $color-white, 2px 2px 5px $color-shadow, and inset 1px 1px 2px $color-shadow, inset -1px -1px 2px $color-white, in hover and active events, respectively.
