Change CSS Dynamically

I need to determine which CSS should be applied on some specific pages. I have a master page which has children and default.aspx and services.aspx are ones of the children of Master page. What I want to is when user navigates Default.aspx or Services.aspx,system should apply DefaultCSS file otherwise I want to apply some ordinary css file.

How can I do that and for this question what kind of practice would be better.

Thanks in advance.

You might want to investigate using themes as well.

Its much easier and more flexible to do this:

MasterPage:

<head>
    <asp:ContentPlaceHolder ID="head" runat="server">
    </asp:ContentPlaceHolder>
</head>

Child-Page 1:

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
    <link href="css/fancyforms.css" rel="stylesheet" type="text/css" />
</asp:Content>

Child-Page 2:

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
    <link href="css/NOTfancyforms.css" rel="stylesheet" type="text/css" />
</asp:Content>

You can include the CSS file declaratively, i.e. in the *.aspx file: see for example this answer.

I think I've found what I am looking for :

protected void Page_Init(object sender, EventArgs e)
    {
        HtmlLink css = new HtmlLink();
        css.Href = "css/fancyforms.css";
        css.Attributes["rel"] = "stylesheet";
        css.Attributes["type"] = "text/css";
        css.Attributes["media"] = "all";
        Page.Header.Controls.Add(css);
    }

Also MSDN was describing how to achieve this : HtmlLink Class
