Dynamic Insertion of CSS block into Webbrowser Control

Question

I have a block of CSS I'm trying to inject into a webbrowser control. I'd do the SetAttribute("src", "filename.css"), but the web page is on https and I get a stupid security exception popping up each time.

So I tried via createElement("style"), but I can find no way of adding the

CSS

.autocomplete {
    font-family: Tahoma;
    font-size: 8pt;
    background-color: white;
    border: 1px solid black;
    position: absolute;
    cursor: default;
    overflow: auto;
    overflow-x: hidden;
}
.autocomplete_item {
    padding: 1px;
    padding-left: 5px;
    color: black;
    width: 100%;
}
.autocomplete_item_highlighted {
    padding: 1px;
    padding-left: 5px;
    color: white;
    background-color: #0A246A;
}

to the element so it can be appended to the head element. The error thrown when I try InnerText or InnerHTML is "This property is not supported". This maybe a case of I'm using the wrong search words again, but can't seem to find a solution to this.

I would recommend moving this out to its own .css file. From there you should be able to use a literal control as such:

<asp:Literal ID="cssInjector" runat="server" Mode="PassThrough" Text="<link rel='stylesheet' type='text/css' media='all' href='/YourCssFileReference.css' />"></asp:Literal>

By specifying the mode as passthrough the literal control acts as an injection point and will pass its text field straight inline.

This should work for you but I can't verify that SSL won't mess it up

This will not work, this is being done in webbrowser control not on a aspx page. It has to be manually inserted after the page loads. I also have javascript that has to be inserted to operate the autocomplete on a text box that will speed up data entry. If I was going to do it as a file I would just create a link instead and set the src and appropriate type.
