Is it possible for a link that is outside an Iframe (On the main page) to open a page inside the IFrame? I wanted to have my navigation on the side of the main page but for the content to be opened inside the IFrame, which will also be included on the main page just to the right of the Nav bar. Thanks in advance!

Make your links like this:

<a href='somepage.html' target='iframename'>Some Page</a>

where iframename is the name of the iframe.

Also, keep in mind that in order for your pages to validate they will need to use the transitional <!DOCTYPE>

I use these lines to make an iFrame:

<iframe
src ="home.html"
width="100%"height="100%">
</iframe>

I then place the following line somewhere outside the iFrame:

<a href='anotherpage.html' target='iframename'>Another Page</a>

What´s the iframename?

<iframe
src="home.html"
width="100%" height="100%"
name="iframename">
</iframe>

Thank you
