HTML META command can be used to instruct the browser to wait specified seconds and then load the web page. This is the code, which can be used to accomplish this requirement:
Change the X to the number of seconds you want to wait before MyWebPage.html is loaded. MyWebPage.html is the HTML page intended to be loaded. This page address can be expressed as either a relative or an absolute URL. Remember that all META commands must be placed in the HEAD section of the HTML code, or somewhere between the and tags.
