Gradient color from left to right

Quick answer：

Gradient colors are a visual effect where colors transition smoothly from one to another. This technique is often used in design, web development, and art to create visually appealing transitions. In web development, for example, gradient colors can be applied to backgrounds, buttons, or other UI elements using CSS or HTML. The 'from left to right' gradient specifies that the color change starts on the left side of the element and moves to the right.
