Hi,
For your information,
(1) Most people here are volunteers just trying to help;
(2) "Online Web Pages" can be in many forms, and that's why detailed
information are much appreciated in order to help.
With that said, you may wish to start with FrontPage Help. To do that,
click Help/Microsoft Office FrontPage Help, and the main FrontPage Help will
be displayed. Click Table of Content, and you will see a list of available
topics.
For topics related to your question, you may wish to read "Creating Web
Pages" and "Creating Web Sites".
Creating Web Pages teaches how to use different techniques and FP features
to compose different types of web pages.
Creating Web Sites teaches how to build up and maintenance a site from
scratch, including how to make a web page available for others to view
online, which is under the sub-topic of Publishing Web Sites, - which also
has been answered by others for your initial question.
Please take some time to read both topics and/or other topics as deem
necessary, which will give you a better picture of how web page and web site
are working altogether with FP.
I am sure people will be more than happy to assist if you could ask more
specific questions with more details.
Hope this helps.
