Say I have something like the following:
<!-- index.html -->
<a href="#heading32">Link to Section</a>
<section id="heading1">Section Name</section>
<div>Content</div>
<section id="heading2">Section Name</section>
<div>Content</div>
<section id="heading3">Section Name</section>
<div>Content</div>
<!-- More sections -->
<section id="heading32">Section Name</section>
<div>Content</div>
<!-- More sections -->
Basically, I want to implement a functionality similar to what you find in sites like Wikipedia, where you click a link in a table of contents and it will scroll your page down to the linked section.
Now, I need to change the code as follows:
<!-- index.html -->
<a href="#heading32">Link to Section in iFrame</a>
<iframe src="content.html">
<!-- content.html -->
<section id="heading1">Section Name</section>
<div>Content</div>
<section id="heading2">Section Name</section>
<div>Content</div>
<section id="heading3">Section Name</section>
<div>Content</div>
<!-- More sections -->
<section id="heading32">Section Name</section>
<div>Content</div>
<!-- More sections -->
Basically, the table of contents will now be in the parent container, and clicking on one should have the iframe content go to the linked section - same functionality as before, only that the content is now relocated.
How should I further modify my implementation to achieve it? The content is exported from a Microsoft Word document and so the content HTML document cannot be modified per se. My system's framework, however, does allow me to add scripts and stylesheets but that's about it.
