Introduction
Welcome back to our series on smashing animations! In this sixth part, we’re diving into the world of SVGs (Scalable Vector Graphics) and how you can leverage the `
What Are SVGs?
SVGs are XML-based vector images that allow you to create graphics that are resolution-independent. This means they scale beautifully across different devices and screen sizes. You can manipulate SVGs with CSS and JavaScript, making them incredibly versatile for animations.

<svg>
<symbol id="icon-star" viewBox="0 0 24 24">
<path d="M12 2l3 7h7l-5 4 2 7-6-4-6 4 2-7-5-4h7z" />
</symbol>
<use href="#icon-star" fill="gold" />
</svg>
Using CSS Custom Properties
CSS custom properties (also known as CSS variables) are a flexible way to manage styling across your webpages. By defining a set of properties, you can easily change the appearance of your SVGs without cluttering your CSS files.
:root {
--star-color: gold;
--star-size: 50px;
}
svg {
width: var(--star-size);
height: var(--star-size);
}
use {
fill: var(--star-color);
}
Step-by-Step Guide to Create SVG Animations
Step 1: Define Your SVG Symbols
Start by defining your SVG symbols. This is where you will create the reusable components.
<svg style="display:none;">
<symbol id="icon-star" viewBox="0 0 24 24">
<path d="M12 2l3 7h7l-5 4 2 7-6-4-6 4 2-7-5-4h7z" />
</symbol>
</svg>
Step 2: Use the `
Now you can implement the `
<svg>
<use href="#icon-star" />
</svg>
Step 3: Style with CSS Variables
Next, define your CSS custom properties to control the color and size.
:root {
--star-color: gold;
--star-size: 50px;
}
svg {
width: var(--star-size);
height: var(--star-size);
}
use {
fill: var(--star-color);
}
Step 4: Adding Animation
Finally, you can add animations using CSS transitions or keyframes.
@keyframes sparkle {
0% { transform: scale(1); }
50% { transform: scale(1.2); }
100% { transform: scale(1); }
}
use {
animation: sparkle 1s infinite;
}
