How to Change the stroke Colour on SVG Graphics in HTML

SVG (Scalable Vector Graphics) is an excellent way to render 2D graphics within HTML. As a web developer or designer, you may want to create interactive elements, like highlighting tracks in a race when hovering with a mouse. In this guide, we'll explore how to change the stroke color of SVG graphics on hover. This will help you create vibrant, engaging visuals for your web projects.

The Challenge: Highlighting SVG Squares on Hover

Imagine you are designing an SVG for Formula 1 tracks, where each track sector lights up a different color when the user hovers over it. You’ve organized your sectors into different SVG groups (like Sector 1, Sector 2, and Sector 3), each assigned a default class for styling purposes. However, when you try to change the colors on hover, nothing happens!

The Initial SVG Setup

Here’s a small snippet of your initial SVG structure:

In this configuration, when you hover over a sector, you want it to change its stroke from white to the respective colors (red, blue, and yellow). However, the default .st0 class does not trigger this change on hover.

The Solution: Using CSS Selectors for Hover Effects

To achieve the desired hover effect, we can leverage CSS selectors more effectively. By specifying id>path:hover selectors, you can directly indicate what happens when a mouse hovers over each sector. Here’s how to implement it:

Step 1: Change the CSS Selectors

Replace the existing class selectors with the following CSS in your SVG style section:

Step 2: Applied SVG Code

Conclusion: Enjoy Dynamic SVG Graphics

By utilizing precise CSS selectors, you can create engaging and interactive SVG graphics. Your tracks will now dynamically change colors based on user interactions, enhancing the overall visual experience. The changes made will elevate your SVG graphics and add a layer of interactivity that captivates users.

Feel free to experiment with additional SVG properties, such as the fill, stroke-width, or even adding transitions to smooth out the color changes. Your web graphics will thank you!
