Shortest (X)HTML5 document

by **zcorpan** » Wed Aug 20, 2008 10:28 pm

Voici à ma connaissance la plus petite page web XHTML 5 valide (10 juin 2007):
<?xml version="1.0" encoding="UTF-8"?><html xmlns="http://www.w3.org/1999/xhtml"><head><title/></head><body/></html>
total: 116 octets; page en question, validité de la page
Pour info, inutile d'essayer de lire le moindre document XHTML 5 avec Internet Explorer (6 ou 7), ce sera peine perdue. Tout document XHTML 5 doit être un document XML (avec donc un en-tête XML), & fourni par le serveur web comme un fichier XML (c'est-à-dire avec un header HTTP du type "Content-Type: text/xml"); IE ne peut lire ce genre de document.
Voici à ma connaissance la plus petite page web HTML 5 valide (9 juin 2007 - 4 août 2007):
<!DOCTYPE html><html><head><meta charset=utf-8><title></title></head><body></body></html>
je me suis rendu compte que je pouvais diminuer encore la taille de cette page en replaçant <meta charset="utf-8"/> par <meta charset=utf-8>; donc -3 octets
total: 89 octets; page en question, validité de la page

Translated by Google:

Here's to my knowledge the smallest web page 5 valid XHTML (June 10, 2007):
<? xml version = "1.0" encoding = "UTF-8"?> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title/> </ head> <body /> </ html>
Total: 116 bytes; page in question, validity of the page
For info, not try to read any document XHTML 5 with Internet Explorer (6 or 7), it will be useless. Any document XHTML 5 must be an XML document (with therefore a header XML), & provided by the web server as an XML file (ie with a header HTTP type "Content-Type: text / xml "); IE can not read this kind of document.
Here's to my knowledge the smallest HTML web page 5 valid (June 9, 2007 - August 4, 2007):
<! DOCTYPE html> <meta <html> <head> charset=utf-8> <title> </ title> </ head> <body> </ body> </ html>
I realized that I could still reduce the size of this page by placing <meta charset="utf-8"/> <meta charset=utf-8>, so -3 bytes
total: 89 bytes; page in question, validity of the page

To the best of my knowledge, the shortest XHTML5 document is

Code: Select all: <html xmlns="http://www.w3.org/1999/xhtml"><head><title/></head><body/></html>

78 bytes

and HTML5:

Code: Select all: <!doctype html><title></title>

30 bytes

Hum... interesting...
I thought I had checked both of these before...
XHTML 5 :
Wasn't the XML file declaration an obligation before, did that change recently? I was sure it was.

HTML 5 :
funny, I was also sure both elements <html> & <heads> were mandatory too. I was also positive that declaring a charset was also an obligation.

I should read the specs again.

ADD: geez, I just realized many things moved since last time I read the specs, I don't understand anything anymore. So we're not supposed to use

Code: Select all: <meta charset="utf-8" />

anymore ?
Is there any document that would be similar to "HTML5 good pratices for dummies" somewhere on the web? The specs got definitely too hard for me to read now.

No, the XML declaration is optional (unless you use some encoding other than utf-8 or utf-16 and a higher-level protocol doesn't declare the encoding).

The elements are required, but the tags are optional (see #omitted in the spec).

You can declare the encoding with HTTP. However, if you're only using ASCII, I think you can get away with not declaring any encoding.

You can use it but you could also use the HTTP Content-Type header to set the encoding...

There's http://dev.w3.org/html5/html-author/ but it's not complete yet.

BTW, what changed in the spec that made it harder to read?

All of this is very interesting, thanks for taking all that time for me.
I'll update (let's say a bit later) my webpage taking what you said into account.
I don't know if it's my memory or something else, but I remembered the specs to be organized in a different way : I thought the stuff about encoding was easier to read, & written at the beginning of the document.

I use the XML declaration for good merit. It also throws IE6 and earlier in to quirks mode which actually for my site produces more desirable behavior in place of IE's standards mode. Not that there is much desirability in IE6 in any mode though it's just I thought I'd add.
