I have done an append using the following code, where `menuElement` is a id of a div and
`appendStr ="<span class="bubbleClass"></span>";`

```
$(menuElement).append(appendStr);

```

However, when i try `$(menuElement+ ".bubbleClass").css("background-color", "red");` it doesnt work.

I want the specific div id stored in menuElement variable to be reflected.
