I have an input form in html, like this:

```
<input type = "text" id ="name" placeholder = "Name"/>

```

I can change the "placeholder" value with:

```
document.getElementById('name').placeholder = Session.get("username")

```

After setting the username to the initial input, but I want to actually change the input into a label (let's say a p tag with strong) with Session.get("username") as its value. How?
