How To Change Stroke Size Svg Css

CSS Programming

Today, I want to share with you the fascinating world of changing the stroke size in SVG using CSS. As a web developer, I always find it thrilling to customize and animate SVG graphics to add that special touch to my web projects. One of the fundamental ways to do this is by manipulating the stroke size, which can have a big impact on the visual appeal of the SVG.

Understanding SVG and CSS

SVG, or Scalable Vector Graphics, is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. CSS, on the other hand, is a style sheet language used for describing the presentation of a document written in a markup language like HTML. When we combine SVG with CSS, we can create powerful and visually appealing graphics that are scalable and customizable.

Changing Stroke Size using CSS

Let’s dive into the exciting part – changing the stroke size of an SVG graphic using CSS. The key property we use here is stroke-width. This property specifies the width of the outline (the “stroke”) on the current element. We can target the SVG element or specific shapes within the SVG to change their stroke width. For example:

svg {

stroke-width: 2px;


In this example, we are setting the stroke width of the entire SVG to 2 pixels. If we want to target a specific shape within the SVG, we can use CSS selectors to pinpoint the element and adjust its stroke width accordingly.

Adding a Personal Touch

As a developer, I often experiment with different stroke sizes to see how they affect the overall look and feel of an SVG graphic. It’s amazing how a simple adjustment in stroke width can completely transform the visual impact of a design. I encourage you to play around with different stroke sizes and observe the changes in real-time. It’s a great way to unleash your creativity and make your web projects stand out.


In conclusion, changing the stroke size of SVG using CSS is a powerful technique that can breathe life into your web graphics. It allows for endless customization and creativity, and the possibilities are truly boundless. So, go ahead, experiment, and let your imagination run wild!
