Alternate to IFrame

From what I understand, IFrame element should be used to display HTML. Unfortunately this element has been deprecated" target="_blank">http://help.sap.com/saphelp_nw04/helpdata/en/e9/7652a84fada444bd11ca73670ce7dc/frameset.htm">deprecated in 2004s, so what's the alternate ?

The problem is as follows:

We would have an "Accept" button on the view, which should pop-up with the legal language and a continue button. Once the user clicks on continue, he would be taken to another view. The legal stuff would come from a URL on the website. We would not like to hard code this as it is subject to change.

Thanks for the help.
