CSS - Implementing Scalable Vector Graphics and Icons in Web Design

Implementing Scalable Vector Graphics and Icons in Web Design in CSS

For icons and other visuals on the web, SVGs (Scalable Vector visuals) provide an adaptable, resolution-independent format. They are therefore perfect for high-quality visual designs on all kinds of screens and gadgets.

SVGs are employed in web design because they are scalable and performant. High-resolution displays especially benefit from the fact that vector drawings can be resized to any size without sacrificing clarity. Furthermore, SVGs are very adaptable since they can be altered using CSS or JavaScript.

Code

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>SVG Example</title>
</head>
<body>
    <svg width="100" height="100">
        <circle cx="50" cy="50" r="40" stroke="green" stroke-width="4" fill="yellow" />
        <text x="50" y="55" font-size="15" text-anchor="middle" fill="black">SVG</text>
    </svg>
</body>
</html>

This HTML has an SVG element right there in the markup.

The SVG is made out of a circle that is centered in a 100x100 viewport and has a yellow fill and green stroke.

Within the circle, there's additional text with the label "SVG" centered.

This example shows how SVG components can be easily styled and scaled when they are directly integrated in HTML.
