What HTML tags are allowed on the three main Metafilter sections? (I dare not experiment for obvious reasons.)

I doubt Matt has them all memorized, so it would probably help to list the ones we know of so far.

Is blink disabled? I tested the ones I hadn't tried in preview (at great fear of actually hitting post by mistake) and nothing happened with that one.

span is dropped, iirc (at least in the main pages; anything goes in the user pages, afaik)

It works in Firefox but not IE.

Don't know how many of these will get stripped once I press post, though.

I did find a problem with <code> and <pre> when I was trying to post snippets of code in this AskMe posting.

A weird "br>" would get stuck in a line... some post-processing thingie that Matt probably wrote. I think it's busted...

Somewhere in MetaTalk, there's a thread that went unanswered. The author of the thread then continued to make little comments and stories in the thread, making fun of the fact that nobody had answered it once it dropped off the front page.

I can't find the thread, but it included a scrolling marquee with a solid bright green background color applied. So, somehow you can do colors. Beats me though.I think I can do the scrolling marquee though...

This seems a good place to post this:

To write the ampersand in &nbsp; one has to use &amp;
So to write &nbsp; you would have to write &amp;nbsp; .
Note that when you hit preview your & will be eaten, so you may wish to use copy/paste accordingly.

Instead of talking about what I allow, I approach the coding by allowing all, and merely blocking truly nefarious things while trusting users to act in good faith.

So you can do anything on the front page, but the following is stripped out:

paragraph tags, since I don't want to encourage people to take up too much vertical space

script tags, since there is very little chance outside of cross-site-scripting hacks that it would be used.

inline styles, also for various cross-site-scripting hack reasons.

Pretty much everything else is allowed, but that doesn't mean you should use it all.

Well, here's my best offering of primitive marquee animation. A lot more seems possible, though, especially with layered blitting like this. Each marquee has as many BRs as necessary for the "layers" in the animation, and with an up or down scroll, each line is shown in sequence one at a time. This one is offset line by line, each marquee containing eight blank frames and one number frame. The topmost has the first frame filled in and eight blanks following, while the second one down has the second frame filled in and a blank first and 2-8th frame... and so on.

sometimes the sun reflecting off the sandbox would hurt our eyes,

you'd have to wrap the thin curly metal bits around your finger

you couldn't tell which way it was going and which part was where.

diary entry: the marquee tag is interpreted very differently in different browsers. In firefox on a PC apparently the browser won't interpret two marquee tags on the same line, so an artificial linebreak is inserted. (thus april 20-22 are broken and the sandbox and loom are double-spaced). In explorer on a mac the height variable is interpreted differently (so the april 19th junk post before the sandbox post is broken and odinstream's post looks like just a line of numbers scrolling smoothly upward.)
at work i've been using safari on a mac:
in safari on the mac a linebreak between two marquee instances doesn't introduce an additional space between each line, so the sandbox is more highly compressed and the loom feels much more like interlocking \/\/\/\/\/\/\'s. all the rest are single character-width marquees lined up next to each other. explorer on pc is closest. i'll have to test firefox on a mac next week.

oh, the fishtank looks nice in firefox/pc. in safari/mac, there are two marquees per line and so the fish collide and the brown bar looks like a mistake.
