How to Dynamically Resize SVG Elements to Fit Their Parent Container?

Expanding/Contracting SVG Elements to Fit Parent Container

In web development, dynamically adjusting the size of SVG elements to match their parent containers is a common requirement. However, setting the viewBox attribute, while commonly suggested, can be problematic when elements within the SVG have fixed dimensions.

To address this, consider working with the SVG itself rather than manipulating the elements within it. Here's how:

1. Create Your ViewBox: Define the viewBox attribute of the SVG element, specifying the desired width and height (e.g., "viewBox='0 0 100 100'"). This sets the size of the viewing area, separate from the SVG's actual dimensions.
2. Limit Element Dimensions to Percentages: Ensure that any elements within the SVG use percentages for their width and height instead of fixed dimensions. For example, a rectangle with dimensions "width='10%'" and "height='20%'" will automatically resize proportionally to the SVG's viewBox.
3. Resize Method: To have the SVG expand atau contract to fit the parent container, add CSS to the SVG element and the container, setting both to have 100% height and width. This ensures that the SVG fills the entire container, adhering to the percentages and the viewBox dimensions.

Alternatively, you can use image embedding with "width='100%'" and "height='auto'" style to automatically scale the SVG proportionally to the available space.

Inkscape, a popular SVG editor, does not offer a global option to set all elements to percentage-based dimensions. However, you can manually convert individual element dimensions to percentages using the "Transform Panel x%" option.
