Dark mode implementation

[azick99]

I have implemented dark mode, but I am not good at web design, and I did not spend much time on color styles. So, feel free to change them any style you want.
all dark colors:

.dark-mode {
    --color-primary: rgb(255, 255, 255);
    --color-secondary: rgb(10, 3, 50);
    --color-card-shadow:rgba(0, 0, 0, 0.088);
    --color-icon:rgb(196, 196, 196);
    --color-dark-blue:rgba(10, 3, 50, 0.227);
    --color-last-btn:rgb(6, 1, 39);
}

You can change them, and it will affect on dark mode color. You do not need to change another place!!
