I have a doubt that in asp.net I am using CssClass class attribute for web server controls. And i am writing all the css code in style.css which will be in style folder of my project
<asp:TextBox ID="UserName" runat="server" CssClass="textEntry"></asp:TextBox>
The above is the example of the textbox.
Now the question is do i need to use link tag to say that my css file is located in style folder of my project?

<style>or<link>tag.
