The plugin runs all imported SVG files through svgo. For index.html, you can use the following syntax: ```html <use svg="file.svg" size="24" /> ``` For scripts, use the `?svg` import query ```javascript import SVG_FILE from './file.svg?svg&size=24 ``` Note: size is shorthand for specifying both width and height individually. You can also set any property of the base SVG element. You can also use the `?svg&icon` query to return a function that allows dynamically resizing the SVG string.
