The mysterious image selector

03/16/2004

Consider the following CSS-styles:

image {
float: right;
}

You'd never expect this one to work, don't you? But surprise, it actually works in 2 browsers: Internet Explorer 6 and Opera 7.x. I am not surprised by Internet Explorer (I never am), but when Opera applied this style, I didn't want to believe it.

Further tests with Opera and a discussion in the Opera forum (thanks Anne) have nailed it down:
It seems to be a misbehaviour of Opera's SGML parser, since the CSS declaration only applies when the page is served as text/html. When served as application/xhtml+xml Opera's XML parser takes over and correctly ignores the style.

Served as text/html
HTML 4.0 Strict/URI
XHTML 1.0 Strict without XML PI
Served as application/xhtml+xml
XHTML 1.0 Strict with XML PI
XHTML 1.0 Strict without XML PI

Go see for yourself. Ahhh, and yes. Mozilla doesn't apply the styles at all!!!!
