"WebTo check the first possibility (we touch a contour line of f ), notice that since the gradient of a function is perpendicular to the contour lines, the tangents to the contour lines of f and g are parallel if and only if the gradients of f and g are parallel. Thus we want points (x, y) where g(x, y) = c and for some where " - Ceres check_gradients

WebA CSS linear gradient can be coded by using the linear-gradient () function and can be as simple or complex as you would like. At the very least, you’ll only need two colors to get started. From there, you could add more colors, angles, directions, and more to customize your gradient even further.
