+
+The **`height`** read-only property of the {{domxref("SVGSVGElement")}} interface describes the vertical size of element as an {{domxref("SVGAnimatedLength")}}. It reflects the {{SVGElement("svg")}} element's {{SVGAttr("height")}} attribute, which may not be the SVG's rendered height.
+
+The CSS {{cssxref("height")}} property takes precedence over the `<svg>` element's `height` attribute, so the value may not reflect the element's appearance. If both the {{SVGAttr("viewBox")}} and `height` attributes are omitted, the `height` property reflects that actual height.
+
+## Value
+
+An {{domxref("SVGAnimatedLength")}}.
+
+## Example
+
+```js
+const svg = document.querySelector("svg");
+const verticalSize = svg.height;
+console.dir(verticalSize.baseVal.value); // the `height` value

+---
+
+{{APIRef("SVG")}}
+
+The **`viewBox`** read-only property of the {{domxref("SVGSVGElement")}} interface reflects the {{SVGElement("svg")}} element's {{SVGAttr("viewBox")}} attribute as an {{domxref("SVGAnimatedRect")}}.
+
+The property describes the `<svg>` element's `<viewBox>` attribute, which is used to defined the x-coordinate, y-coordinate, width, and height of an `<svg>` element. The {{domxref("SVGAnimatedRect.baseVal")}} and {{domxref("SVGAnimatedRect.animVal")}} properties are both {{domxref("SVGRect")}} objects, or `null` if the `viewBox` is not defined. These objects' components my differ from the {{domxref("SVGSVGElement.x")}}, {{domxref("SVGSVGElement.y")}}, {{domxref("SVGSVGElement.width")}} and {{domxref("SVGSVGElement.height")}} properties, as the {{SVGAttr("x")}}, {{SVGAttr("y")}}, {{SVGAttr("width")}}, and {{SVGAttr("height")}} attributes take precedence over the `viewBox` attribute.
+
+For non-nested SVG elements, the values of the CSS {{cssxref("x")}}, {{cssxref("y")}}, {{cssxref("width")}}, and {{cssxref("height")}} properties take precedence over any element attributes, so the values defined by the `viewBox` may not be reflected in the element's appearance.
+
+## Value
+
+An {{domxref("SVGAnimatedRect")}}.
+
+## Example
+
+Give the following SVG opening tag:
+
+```html
+<svg viewbox="-12 -18 200 300" x="5" y="5" height="400" width="600"></svg>
+```
+
+We can retrieve the viewBox values, but they differ from the {{domxref("SVGSVGElement.x", "x")}}, {{domxref("SVGSVGElement.y", "y")}}, {{domxref("SVGSVGElement.width", "width")}}, and {{domxref("SVGSVGElement.height", "height")}} properties:
+
+```js
+const svg = document.querySelector("svg");
+const vBox = svg.viewBox;
+
+// The SVGSVGElement viewBox property
+console.dir(vBox); // SVGAnimatedRect { baseVal: SVGRect, animVal: SVGRect }
+​console.log(vBox.baseVal.x); // -12
+​console.log(vBox.baseVal.y); // -18
+​console.log(vBox.baseVal.width); // 200
+​console.log(vBox.baseVal.height); // 300
+
+// Other SVGSVGElement properties
+​console.log(svg.x); // 5
+​console.log(svg.y); // 5
+​console.log(svg.width); // 400
+​console.log(svg.height); // 600
+```

+
+The **`x`** read-only property of the {{domxref("SVGSVGElement")}} interface describes the horizontal coordinate of the position of that SVG as an {{domxref("SVGAnimatedLength")}}. When an {{SVGElement("svg")}} is nested within another `<svg>`, the horizontal coordinate is a length in the user coordinate system that is the given distance from the origin of the user coordinate system along the x-axis. Its syntax is the same as that for [`<length>`](/en-US/docs/Web/SVG/Content_type#length).
+
+It reflects the {{SVGElement("svg")}} element's {{SVGAttr("x")}} geometric attribute. The default value is `0`. The `x` attribute has no effect on outermost `<svg>` elements; only one nested ones. The CSS {{cssxref("x")}} property takes precedence over the `<svg>` element's `x` attribute, so the value may not reflect the element's appearance.
