So sorry for the late response ! But thank you for your kind words ♡ For the lines I put this in the CSS section in account settings

body::before { content: " "; display: block; position: fixed; top: 0; left: 0; bottom: 0; right: 0; background: linear-gradient(rgb(155 206 202 / 40%) 40%, rgb(191 252 226 / 0%) 40%); z-index: 2; background-size: 100% 2px, 3px 100%; pointer-events: none; }

You can adjust the RGB to be whatever colors you want, you can also adjust the percentages for intensity

For the gradient I put linear-gradient(#hexcode, #hexcode) in whatever box I wanted ( ˶ ᷇ 𖥦 ᷆ ˵ ) ! For example the super raised theme setting
