In the past I’ve been able to modify the CSS on a page via an inline style tag.
I know this sounds horrible but it’s for custom CSS writing while working on a kind of WYSIWYG (not with text though).

I used to do something like:
tag.styleSheet.cssText = myrules;

I don’t know when exactly, but at some point IE started saying “Invalid Argument” when I try this. The real crux is that doing tag.innerHTML = 'body {}' gives Unable to set value of the property 'innerHTML': object is null or undefined which doesn’t happen in any other browser.

EDIT

To be clear I am using an inline style tag. I am not trying to use the inline style attribute.

<style type="text/css" id="mytag"></style>

How can I change the inside of that tag?

EDIT 2
Please see this fiddle:

It appears that my solution of tag.styleSheet.cssText is identical to using styleSheets property. You can comment out the last definition of cssText to see it working as proposed by @Teemu. So now I’m real lost why it’s not working in my app. If anyone has ideas what could break that functionality that would be great. In the meantime I’ll be tinkering around my app.

    IE is limited to 32 stylesheets. I like to forget that fact apparently, which seems to include inline style tags, on top of <link>.

    I changed my sandbox to turn on minification so it would put the files together.

    Then my code worked.

    So it appears that when you go over the limit and insert via JS, you don’t get a real error until you try what I did.
