About the svg view element: https://developer.mozilla.org/en-US/docs/Web/SVG/Element/view
It can be used to create views referable like
<svg id="total">
<view id="view-1" viewBox="..." />
<circle cx="1" cy="1" />
</svg>
<img src="#view-1" />

about the css :target selector (matches the element with the id specified by the url document-fragment)
and the svg <view> element, which specifies a viewBox and can have an id.

that you can pass default values to css variable references, e.g. var(--button-color, pink)
Also,
If the SVG fragment identifier addresses a time segment (e.g., MyDrawing.svg#t=10),then the initial view into the SVG document is established as if no fragment identifier was provided. The rendering of the SVG Document shall be as if the setCurrentTime method on the SVG Document element had been called with the begin time value from the fragment identifier. Additionally, if an end time value is provided in the fragment identifier, the effect is equivalent to calling the pauseAnimations method on the SVG Document when the document time reaches the end time of the fragment identifier.
