How to use CSS to achieve a gradient effect with thin strips in the middle?

This article will explore how to use CSS linear gradients to create a gradient effect with thin lines in the middle shown in the picture. We will analyze the implementation method in detail and provide CSS code that can be used directly.

To achieve this effect, the key is to cleverly use the linear-gradient attribute. This property allows us to define the gradient color and its position in the gradient, thereby accurately controlling the visual effects of the gradient.

The following CSS code can generate similar effects:

 .line-horizontal {
  width: 100px;
  height: 1px;
  background: linear-gradient(to right, rgba(255,255,255,0) 0%, rgba(255,255,255,1) 50%, rgba(255,255,255,0) 100%);
}

Code parsing:

• .line-horizontal : This is a CSS class selector that selects elements that need to apply gradient effects.
• width: 100px; height: 1px; : Set the width and height of the element, and control the length and thickness of the thin line.
• background: linear-gradient(to right, ...) : Define linear gradient. to right specifies the gradient direction from left to right. You can also use angular values, such as linear-gradient(45deg, ...) .
• rgba(255,255,255,0) 0% : The gradient start position (0%) is completely transparent white.
• rgba(255,255,255,1) 50% : The middle position of the gradient (50%) is completely opaque white, forming thin lines.
• rgba(255,255,255,0) 100% : The gradient end position (100%) is completely transparent white.

By adjusting the alpha value (transparency), percentage value, and the orientation of linear-gradient in rgba value, you can easily create thin line gradient effects in a variety of different colors and widths. For example, changing the value by 50% can adjust the width of the thin line. Use different rgba color values ​​to create colored thin lines. Hopefully the above explanation can help you understand and achieve similar CSS gradient effects.
