HTML CODE for delaying the animated loading bar after the link will open?

[Bench]

i have a problem creating an animated loading bar (I want somthing like this "When you click a button it will load a generating or loading bar after link will open")i created a webpage i just want to put a animation in between the button and the link so that it will look so real like is was generating some report or something but it was only link in the excel. My question is can you help make a html code on this?or is there any formula in delaying to open the link after the animated loading bar is completed?

There is no HTML "code" for this. HTML is not a programming language, it is a document markup language. You will need to use either PHP, JavaScript, or ASP.NET to do what you are wanting to do.
