Question: My team was Plan to migrate from RTC to the TFS VC scm. I haven't found a lot of info about migrating out of RTC into TFVC in general.
What will be the best way to migrate our source code and change history from RTC to TFVC?

Answer: 
You are trying to apply a style where you should be applying a class. Try this:

CSS:

```
.todo-complete {
    text-decoration: line-through;
}

```

HTML:

```
<p ng-class="{'todo-complete': toDoArray[$parent.$index].subItemVal.completed === 'true'}">{{subItem}}</p>

```
the error is because you have a plus quote

```
<p ng-class="''toDoArray[$parent.$index].subItemVal.completed === 'true' && {'text-decoration': 'line-through'}">{{subItem}}</p>

change to 
<p ng-class="'toDoArray[$parent.$index].subItemVal.completed === 'true' && {'text-decoration': 'line-through'}">{{subItem}}</p>

```
