How to Dynamically Resize SVGs to Fit Parent Containers?

Dynamically Resizing SVGs Within Parent Containers

Expanding or contracting an SVG element to fit its parent container can be a common task.

Using the viewBox Attribute

The primary approach involves setting the viewBox attribute on the SVG element. However, this may not work when elements within the SVG have defined widths and heights.

Percentage-Based Dimensions

For elements with defined dimensions, using percentage-based widths and heights can ensure the SVG responds to container size changes. However, if an external SVG file renders correctly without percentage values, this raises questions about the necessity of specifying them.

Inkscape Settings

If you prefer to work within Inkscape, you can set up your SVG document to utilize percentage dimensions. This ensures that all elements within the document will automatically scale with the container size. Here's how to do it:

Method:

1. Open Inkscape.
2. Create a new SVG document (File → New).
3. Click "Edit → Preferences."
4. Navigate to "SVG Output."
5. In the "Units" section, select "Relative to width and height of object" from the "Unit System" dropdown and click "Apply."

With this setting enabled, all newly created and imported elements will inherit percentage-based dimensions, ensuring they scale dynamically within parent containers.
