Yes, sure. Now, with some sites it's not clear whether something is a bug, bad HTML, contradicting directives, etc. IMHO, just there, having an easy (i.e. user ready, click-click) way to customize can help a lot. e.g.[1] Here, I don't know what's wrong, but reading the text in those colors clearly hurts. Avoiding embedded CSS "solves" the problem with one click (from a user perspective). I may try coding it a bit and check how it feels.

Yes, but this solution requires good knowledge on CSS and HTML and some digging time (as in the example above where we don't know the problem in advance). OTOH, clicking a pair of checkboxes and see whether that helps is much easier. It's a user-level "solution". > While we're at this: Attached is a page which renders differently in > dillo and Firefox; the latter closes the "em" implicitely, so that the > red box is below (not inside) the green one.

IMO this is a good place to nail some "rendering bugs" (by reacting as FF to bad HTML). AFAIR, the HTML cleanup heuristics were tuned before DIV was supported! I'll work on this now. Please let me know of any other tags you've found in real pages that mess with DIV in this sense while I work on it (for instance EM is in the phrase set which should be treated similarly). It may end helping rendering of a lot of sites or just a few, who knows, but's definitely worth the try. See attached toy-patch for the test case. -- Cheers Jorge.-

While examining why the images are not shown, I noticed that some element is set at height 0. Test the attached page in dillo and Firefox and notice the difference: Firefox shows the first line, although it has height 0, but draws the second line at the same position as the first, the latter shining through. It is somewhat difficult to imitate this behavour [1]; but two solutions are feasable: (i) ignore height (perhaps via user style sheet); (ii) use 'height' only to make elements larger (somewhat similar to 'adjust_min_width'). In both cases, the two lines would be put on top of each other. Sebastian [1] Complicated cases of overlapping elements are handled in the "dillo_grows" repository, at <http://flpsed.org/hgweb/dillo_grows>.

This works now, too. BTW, there were a couple of bugs occurring here. Sebastian

First of all, let's see how many problems fall into the "plain bug" category, and so are simple to fix (although it needs work and time). Partly, this kind of customization is already possible by usage of user style sheets; perhaps we could add a (proprietary) extension for selecting specific sites. While we're at this: Attached is a page which renders differently in dillo and Firefox; the latter closes the "em" implicitely, so that the red box is below (not inside) the green one.

I'm imagining, but I have no code, writing stream filters to edit websites until I like them. My first proposed victim would be gmail, to make plain html gmail take less vertical real-estate on my width of monitor. This would be fairly un-userproof.
