‘React-svg library and styles are not applied’ – a phrase that can send shivers down the spine of any React developer. You’ve spent hours crafting the perfect SVG icons, only to find that your styles are being ignored. In this article, we’ll delve into the world of React-SVG and explore the common pitfalls that can lead to this frustrating issue. By the end of this guide, you’ll be equipped with the knowledge to troubleshoot and solve the problem once and for all.
What is React-SVG?
Before we dive into the solution, let’s take a brief look at what React-SVG is and why it’s an essential library for any React developer. React-SVG is a popular library that allows you to use SVG icons as React components. It provides an easy way to handle SVG icons, making it possible to scale, style, and animate them with ease.
The Benefits of Using React-SVG
- Easy to use: React-SVG provides a simple API that makes it easy to integrate SVG icons into your React application.
- Customizable: With React-SVG, you can style and animate your SVG icons using CSS and JavaScript.
- Scalable: React-SVG allows you to scale your SVG icons without losing quality, making it perfect for responsive design.
- Accessible: React-SVG provides an accessible way to use SVG icons, making it easy to create accessible React applications.
The Problem: React-SVG Library and Styles Are Not Applied
Now that we’ve covered the basics of React-SVG, let’s address the issue at hand. You’ve installed React-SVG, imported the library, and created your SVG icon component. However, when you try to apply styles to your SVG icon, nothing happens. Your styles are being ignored, and you’re left wondering what’s going wrong.
- Importing the incorrect SVG file: One of the most common causes of this problem is importing the incorrect SVG file. Make sure you’re importing the correct SVG file and that it’s in the correct format.
- Incorrectly configuring the SVG component: Another common cause of this problem is incorrectly configuring the SVG component. Ensure that you’re passing the correct props to the SVG component and that you’re using the correct syntax.
- Conflicting CSS styles: Conflicting CSS styles can also cause this problem. If you have multiple CSS files or stylesheets that are applying conflicting styles to your SVG icon, it can prevent the styles from being applied.
- Using an outdated version of React-SVG: Using an outdated version of React-SVG can also cause this problem. Make sure you’re using the latest version of the library to ensure compatibility and avoid issues.
Solving the Problem: Step-by-Step Guide
Now that we’ve covered the common causes of the problem, let’s take a step-by-step approach to solving it. Follow these instructions carefully to ensure that your React-SVG library and styles are applied correctly.
Step 1: Verify Your SVG File
First, verify that your SVG file is correct and in the correct format. Open your SVG file in a text editor or an SVG editor like Adobe Illustrator to ensure that it’s a valid SVG file. If you’re using an SVG file from a third-party source, ensure that it’s compatible with React-SVG.
<svg width="24" height="24" viewBox="0 0 24 24">
<path d="M12 2C6.48 2 2 6.48 2 12C2 17.52 6.48 22 12 22C17.52 22 22 17.52 22 12C22 6.48 17.52 2 12 2Z"/>
</svg>Step 2: Import the Correct SVG File
Next, ensure that you’re importing the correct SVG file in your React component. Use the following syntax to import the SVG file:
import React from 'react';
import { SvgIcon } from '@material-ui/core';
import checkmark from './checkmark.svg';
const CheckmarkIcon = () => {
return <SvgIcon>
<{checkmark}>
</SvgIcon>;
};Step 3: Configure the SVG Component Correctly
Now, configure the SVG component correctly by passing the correct props and using the correct syntax. In this example, we’re using the `SvgIcon` component from Material-UI:
import React from 'react';
import { SvgIcon } from '@material-ui/core';
import checkmark from './checkmark.svg';
const CheckmarkIcon = () => {
return <SvgIcon viewBox="0 0 24 24">
<{checkmark}>
</SvgIcon>;
};Step 4: Apply Styles to the SVG Icon
Now that we’ve configured the SVG component correctly, let’s apply styles to the SVG icon. We can use CSS to style the SVG icon:
.checkmark-icon {
fill: #333;
width: 24px;
height: 24px;
}<CheckmarkIcon className="checkmark-icon" />Step 5: Verify the Solution
Finally, verify that the solution is working correctly by checking the DOM elements and the applied styles. Use the browser’s developer tools to inspect the SVG icon and verify that the styles are being applied correctly.
Common Pitfalls to Avoid
While solving the problem, it’s essential to avoid common pitfalls that can cause the issue to persist. Here are some common mistakes to avoid:
- Using inline styles instead of CSS classes: Avoid using inline styles to style your SVG icon. Instead, use CSS classes to apply styles to the SVG icon.
- Not using the correct viewBox: Ensure that you’re using the correct viewBox attribute in your SVG component. This attribute defines the visible area of the SVG icon.
- Not using the correct namespace: Ensure that you’re using the correct namespace in your SVG file. The namespace defines the XML namespace for the SVG element.
- Not using the correct file format: Ensure that you’re using the correct file format for your SVG file. React-SVG supports SVG files in the SVG 1.1 format.
Conclusion
In conclusion, solving the problem of React-SVG library and styles not being applied requires a step-by-step approach. By verifying your SVG file, importing the correct file, configuring the SVG component correctly, applying styles, and verifying the solution, you can ensure that your React-SVG library and styles are applied correctly. Remember to avoid common pitfalls and use the correct syntax and formatting to ensure that your SVG icons are displayed correctly in your React application.

Frequently Asked Questions
Stuck with the react-svg library and can’t seem to get those styles to apply? Worry not, friend! We’ve got you covered with these top 5 FAQs to get you back on track.
Why aren’t my styles applying to the SVG elements?
This is a common gotcha! Make sure you’re using the `svg` prop instead of `className` to apply styles to the SVG elements. For example, `
I’ve tried the `svg` prop, but my styles still aren’t working. What’s going on?
Check if you’re using a CSS-in-JS solution like Styled Components or Emotion. Sometimes, these libraries can clash with the react-svg library. Try using a regular CSS file or a CSS module to see if that resolves the issue. And if all else fails, try applying the styles directly to the SVG element using the `style` attribute.
How do I apply global styles to my SVG icons?
Easy peasy! You can use a global stylesheet to apply styles to all your SVG icons at once. Just create a separate CSS file, import it into your main app file, and target the SVG elements using CSS selectors. For example, `svg.icon { fill: red; }`. This way, you can keep your styles organized and reusable across your entire app.
Can I use CSS variables with react-svg?
You bet! React-svg is fully compatible with CSS variables. Just define your variables in a global stylesheet, and then use them in your SVG components. For example, `:root { –icon-color: red; }` and then `
What if I need to apply styles to a specific part of the SVG element?
No problem! You can use the `component` prop to target a specific part of the SVG element. For example, `
