Well, my site usually uses Frames, but I wanted to organize everything in a table, so I put in an Iframe, I can't change the size of them, I don't know why, I want the area with the content to be wider, and the area with the links to be thinner. I'm really puzzled, can anyone help?
If you are looking to progress, moving to tables and inline frames is not the answer. Using frames isn't completely bad; however, it can be replaced by server side includes, which gives access to users whose browsers don't support frames.
As for answering your question, the inline frame can easily be re-sized via the style attribute:
<iframe ... style="height:400px;width:80%"> </iframe>
However, I will reiterate that moving towards tables and inline frames is worse than using frames themselves. I owuld suggest instead a move towards CSS and towards a server side solution.
