HMTL5 Tags for IE 7/8

I’ve been using the blankslate for a base for quite some time now, its fantastic, however I have some qualms with HTML5 Tags.

Some of the tags implemented work with IE8/7, however some do not.
Not fully working:

• header
• sections
• article

What seems to happen with these is they contain no text, because IE is treating them as inline-styles.

So my question is, how can this be resolved?

I’ve looked at this solution:

<script type="text/javascript">
       document.createElement('header');
       document.createElement('nav');
       document.createElement('article');
       document.createElement('section');
       document.createElement('footer');
     </script>

But this doesn’t work either.
