Function getComputedStyle

getComputedStyle(element: HTMLElement | SVGElement, name: string): string
Reads a computed style value from an element, including CSS custom properties.
Parameters
- element: HTMLElement | SVGElement
  HTML or SVG element whose computed styles to read.
- name: string
  CSS property in camelCase (e.g. "lineHeight") or a custom property (e.g. "--space-10").
Returns string
The computed value as a string; custom properties use getPropertyValue, standard properties prefer direct CSSStyleDeclaration access.
Example
```
const el = document.createElement("div");

getComputedStyle(el, "color"); // e.g. "rgb(0, 0, 0)"
getComputedStyle(el, "lineHeight"); // e.g. "normal"
getComputedStyle(el, "--space-10"); // "" until the custom property is set
```
