How can I code the color of background that get darker to left ?

Answer 1

You could use CSS to apply a linear-gradient, e.g. {background-image: linear-gradient(to left, color 1, color 2)}, where color 1 and color 2 are the same color but color 1 is lighter and color 2 is darker.

Answer 2

If you select the colors using HSL (Hue, Saturation, Lightness) they could have the same hue and saturation but different lightness values so one would be darker than the other.

Answer 3

Use something like this in CSS.
Using deg allows you to customize the angle of the gradient.

Here's an example:
background-color { linear-gradient(90deg,
rgba(196,125,244,1) 0%,
rgba(255,104,104,1) 50%,
rgba(255,208,142,1) 100%);
}
