      <h3>${title}</span></h3>
      <h2 id="${value.ref}">${value}</h2>
  </div>
  
```
    Notice that, references (like "${value.ref}" in the example above) can be added to any of the HTML elements so that they can be referenced from the Javascript template. See DisplayerSettingsBuilder.jsTemplate(String) for further details.
    Specified by:
    
    htmlTemplate in interface DisplayerSettingsBuilder<T>
    
    Parameters:
    html - The HTML template used to render the displayer. The following enumeration contains all the available variables:
    
    id: An identifier that it is unique among all the displayers
    
    title: The metric title
    
    value: The formatted value

  - jsTemplate
```
public T jsTemplate(String onDrawJs)
```
    Description copied from interface: DisplayerSettingsBuilder

```
  <div class="card-pf card-pf-accented card-pf-aggregate-status"
      style="background-color:${bgColor}; width:${width}px; height:${height}px; margin-top:${marginTop}px; margin-right:${marginRight}px; margin-bottom:${marginBottom}px; margin-left:${marginLeft}px;">
      <h3>${title}</span></h3>
      <h2 id="${valref}">${value}</h2>
  </div>
  
```
    It is possible to implement some conditional into the JS so that the color of the text displayed depends on its value:
```
  ${valref}.style.color= ${value.raw} > 1000 ? "red" : "black";
  
```
    where the "${valref}" is the identifier of the HTML element holding the value.
