I have an element with `class='myTestClass'`. How do I apply a css style to all children of this elements? I only want to apply the style to the elements children. Not its grand children.

I could use

```
.myTestClass > div {
  margin: 0 20px;
}

```

which work for all `div` children, but I would like a solution which works for all children. I thought I could use `*`, but

```
.myTestClass > * {
  margin: 0 20px;
} 

```

does not work. 

Edit

The `.myTestClass > *` selector does not apply the rule in firefox 26, and there is no other rule for margin according to firebug. And it works if I replace `*` with `div`.
