Hi,

In our graduate essay repository large abstracts are used. Can I
restrict the number of rows of the abstract on the summary page?
(something like the 'input_rows' property in 'eprints_fields.pl' would
be nice)

Regards,

  Arnoud.

How about putting it in an iframe so that it scrolls?

But to make it easier, use a data url so you don't need a second page.

I've made a nice example here:

Hmm, so I guess this needs some hacking of eprint_render.pl

But I wonder how iframes would influence the accessibility. At least a
fall back link to the abstract for non-iframes supporting browsers would
be needed..

Would a CSS <div> solution with overflow not be better? Or is this not
yet matured (I would hate to get into cross-browser development issues
again)

This is a multi-part message in MIME format.
Nah, overflow's pretty mature. You could use that.

Ok, I constrained long abstracts with CSS overflow and max-height. Needs more ↵
testing, but works in all my browsers:
 
* Added in /cfg/static/style/auto/zzz_local.css
 
.ep_block_scroll {
  overflow: auto;
  width: auto;
  max-height: 10em;
  margin: 0.25em auto 0.25em auto;
  text-align: left;
}
 
* Changed  class to "ep_block_scroll" for abstract in ↵
/cfg/cfg.d/eprint_render.pl
 
* generate_static and generate_abstracts
 
(might need a workaround for the overflow bug in IE6)

It does :(

To get this working in IE6 (which is still used a lot), I had to add
this to the CSS:

/* IE6 workaround */

* html .ep_block_scroll {
	width: 100%;
	height: 15em;
}
