ContentLoader is a meta loader while other loaders are just higher-order components of it. By default ContentLoader only displays a simple rectangle, here's how you can use it to create custom loaders:
<ContentLoader viewBox="0 0 250 110">
<rect x="0" y="0" rx="3" ry="3" width="250" height="10" />
<rect x="20" y="20" rx="3" ry="3" width="220" height="10" />
<rect x="20" y="40" rx="3" ry="3" width="170" height="10" />
<rect x="0" y="60" rx="3" ry="3" width="250" height="10" />
<rect x="20" y="80" rx="3" ry="3" width="200" height="10" />
<rect x="20" y="100" rx="3" ry="3" width="80" height="10" />
</ContentLoader>
This is also how ListLoader is created.
You can also use the online tool to create shapes for your custom loader.

Examples
Responsiveness
To create a responsive loader that will follow its parent container width, use only the viewBox attribute to set the ratio:
<ContentLoader viewBox="0 0 300 200">
<!-- ... -->
</ContentLoader>
To create a loader with fixed dimensions, use width and height attributes:
<ContentLoader width="300" height="200">
<!-- ... -->
</ContentLoader>
Note: the exact behavior might be different depending on the CSS you apply to SVG elements.
