Hi,

I am working on a website I am confused with the following,

What is the main difference between

<body>.....</body>

and

<body runat="server">...</body>

and in which situations which one is better. Is there any benefit if i put runat="server"

For server controls we will add attribute runat="server". Why we use it for body tag.

Hi,
If you are using Master Pages in an ASP.NET application and you need to add an attribute to the <BODY> tag from a Content Page -- for instance, to set a client script function for the onload event of the page -- you will find that you can't do it directly because the <BODY> tag is in the Master Page, not in your Content Page.
Here you go:
Adding attributes to the <body> tag when using Master Pages[^]

All the best.

runat="sever" means it is the ability to take a "normal" client-side HTML control and "upgrade" it to a server control

runat="sever" means it is the ability to take a "normal" client-side HTML control and "upgrade" it to a server control; and giving it an id is primarily there to migrate older non-ASP .NET application to ASP .NET.

Any element marked with runat="server" lets the framework know that this will be a control on the server side. This article has more details:

Not all controls included within the body tag may be run at server.

Based on your question, this blog[^] makes an interesting read.
