I'm about to adjust position of an element based on another element. and need to know the `left` value of other element. The problem is: DOM object has empty value for `left` property of style, And i just can't get the source element position.  

assume some thing like this: 

```
export class SomeComponent {
  ...
  ShowDropdownContent(dropdown){
    console.log(dropdown.style.left);//Loggs an empty string.
  }
  ...
}

```

Meanwhile in `jquery` we simply call: `$('SomeSelector').position().left`.  

Has `angular` any equivalent of this? (specially when DOM's left value of element is empty).
