Text on top of img in IE6?

Hi,

because IE doesn't handle SVG natively, I have created an alternate HTML
output format for makeppgraph. I have thumbnails of 200px on the longer side,
so there is enough space to put a little text for the alternate link on top of
the img. The way I have implemented it, with two little css classes works
nicely in all browsers except IE6 (haven't got access to 7).

I've tried z-index, "* html * .pict" etc., all to no avail. Could somebody
please look at http://makepp.sourceforge.net/gallery/ and tell me how to get
it to work in all browsers.

I don't believe I have a solution to your problem, but maybe some of
this (mostly debugging advice but with some babbling guesswork) will help.

Step One is always to validate the code. You may be amazed to find the
report "Failed validation, 162 Errors" when validating your markup at
http://validator.w3.org/ . Fortunately, the problems are easy to fix
(you may be amused to see what they are.)

The URL is to your complete page. We only need a URL to a reduced form
of the page which still exhibits the problem, so a page with the code

<h2 id="suffixes">Suffixes
<span class="pict">
<a href="suf.svg">
<img src="suf.gif" border="0" height="108" width="200">
</a>
<br />
<a href="suf.html" class="bluebg">HTML variant</a>
</span>
</h2>

(within <body> etc., incl. the relevant CSS, which for this page you
have embedded already) would have been enough. Now we can look at what
the problem might be with less distraction.

I don't think I would have included the images as part of <h2>. I
believe I would have used markup more like

<h2 id="suffixes">Suffixes</h2>
<div class="pict">
<a href="suf.svg">
<img src="suf.gif" border="0" height="108" width="200">
</a>
<br />
<a href="suf.html" class="bluebg">HTML variant</a>
</div>

Your CSS is (close to)

..pict { padding-left:5px; float:right;
font:small normal; line-height:1%; }
..bluebg { background:url(/1.50/pre.png) repeat-y white;
padding:2px 3px; }

I've removed the duplicate background color on .bluebg. I would drop the
normal from .pict's font declaration (using small for font-size is
probably not too bad a decision).

The line-height declaration is funny; what do you mean with it? It's 1%
here, which means 1% of "small", which would make the line-height pretty
damned small indeed. Here, there's obviously another minimum size being
used (although I don't know what the rules are for that).

You said you tried z-index, but that will only work for positioned
elements, and maybe yours weren't. Maybe one solution would be to
replace the float:right with some position:absolute and right:0
declarations. So maybe something like

..pict { font-size:small; position:relative;}
..pict a { position:absolute; top:0px; right:0; }
..pict a.bluebg {
background:url(/1.50/pre.png) repeat-y white; padding:2px 3px;
top:90px; right:120px; z-index:5; }
#suffixes { margin:0; }


You started your post by muttering about native SVG support in IE. It
seems that my Firefox doesn't seem to have it either, although maybe my
version here is just too old. I can't do anything but download the SVG
file anyway.

HTH, somehow.

That's a good point! Most of the other pages on that site are generated by
Perl's pod2html though, so I have little control over the quality :-(
The URL is to your complete page.

I thought about that, but I wanted you to see the thumbnails in context,
sometimes two side by side...

font:small normal; line-height:1%; }
.bluebg { background:url(/1.50/pre.png) repeat-y white;
padding:2px 3px; }

I've removed the duplicate background color on .bluebg.

I wondered about that one too, but the guide at Self HTML (very popular in
Germany) doesn't mention colour as possible in "background", so I wanted to be
sure.
I would drop the
normal from .pict's font declaration (using small for font-size is
probably not too bad a decision).

here, which means 1% of "small", which would make the line-height pretty
damned small indeed. Here, there's obviously another minimum size being

I just guessed that way the line would be sucked up. And everybrowsy but IE
does that.
You said you tried z-index, but that will only work for positioned
elements, and maybe yours weren't. Maybe one solution would be to
replace the float:right with some position:absolute and right:0
declarations. So maybe something like

.pict { font-size:small; position:relative;}

.pict a.bluebg {
background:url(/1.50/pre.png) repeat-y white; padding:2px 3px;
top:90px; right:120px; z-index:5; }
#suffixes { margin:0; }

That's not quite the same, because at least both in Opera and Konqueror the
next paragraph is overlapped by the img, rather than flowing around it.
Probably due to position:absolute, which I never quite understood, but
relative instead is worse...

Must be quite old, I surely tried it at least a year back. With all the
security holes that have surfaced, I wouldn't go near an old version (nor IE,
but at least I want others to be able to see the page).
