I got the page (can control the content) which can only run html (not javascript) like this:

```
<style>
h1 { color:red }
</style>
<object data=something.html ></object>

```

in something.html, it contains:

```
<h1>
simple example
</h1>

```

and the css not work in this case, I expect the `simple example` to be red, it still black. Is there possibly any way that my css affect the rendered html source? (can replace object tag with any tag)
