🙋 Introduction

SVG (Scalable Vector Graphics) provides a powerful way to create vector graphics for the web. One of the advanced features in SVG is the ability to apply linear gradients to shapes. Linear gradients create a smooth transition between two or more colors along a straight line, adding depth and dimension to your graphics.

In this guide, we will explore how to create and use SVG linear gradients.

💡 Syntax

To define a linear gradient in SVG, you use the <linearGradient> element within a <defs> block, followed by the <stop> elements to specify the gradient colors. The gradient is then applied to an SVG shape using the fill attribute. Here's the basic structure:

Syntax

Copied

<svg>
  <defs>
    <linearGradient id="gradientID" x1="start-x" y1="start-y" x2="end-x" y2="end-y">
      <stop offset="percentage" stop-color="color" />
      <!-- Add more <stop> elements as needed -->
    </linearGradient>
  </defs>
  <shape fill="url(#gradientID)" />
</svg>

🧰 Attributes

id: A unique identifier for the gradient.
x1, y1: Coordinates for the starting point of the gradient (usually 0%).
x2, y2: Coordinates for the ending point of the gradient (usually 100%).
offset: Specifies where the gradient stop is placed, typically a percentage (e.g., "0%", "50%", "100%").
stop-color: The color at the gradient stop.

📄 Example

Let's create an SVG rectangle filled with a linear gradient:

index.html

Copied

<svg width="200" height="200">
  <defs>
    <linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
      <stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
      <stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
    </linearGradient>
  </defs>
  <rect width="200" height="200" fill="url(#grad1)" />
</svg>

🧠 How it works?

In this example, we define a linear gradient that transitions from yellow to red horizontally. The gradient is then applied to a rectangle that fills the entire SVG canvas.

🎉 Conclusion

SVG linear gradients enhance the visual appeal of your graphics by allowing smooth color transitions. They are easy to implement and highly customizable, making them a valuable tool for web designers and developers.

By mastering linear gradients, you can add a professional touch to your SVG artwork.
