Possible Duplicate:
ASP.net render meta tag validly

This is in my .aspx file:

<meta name="viewport" runat="server" content="width=380,height=575" id="viewPort" />

This is what appears on the rendered HTML file in the browser:

<meta id="viewPort" name="viewport" content="width=380,height=575"></meta>

What actually appears is not HTML5-compliant.

Any idea why that is changing?

Answer 1

This behaviour is obviously by design of ASP.NET:

Workaround 1:
Add the following code into your page_load event:

HtmlMeta keywords = new HtmlMeta();
keywords.Name = "keywords";
keywords.Content = "one two trhee;
Header.Controls.Add(keywords);

see: ASP.net render meta tag validly

Workaround 2:

protected internal override void Render(HtmlTextWriter writer)
{
    if (base.EnableLegacyRendering)
    {
        base.Render(writer);
    }
    else
    {
        writer.WriteBeginTag(this.TagName);
        this.RenderAttributes(writer);
        writer.Write(" />");
    }
}
