Safari is, by and large, a browser with pretty good standards
support. However, it has a few missing features, a few bugs, and a fair
few things that are correct according to the spec but aren’t the same
interpretation as other standards-compliant browsers. This page
discusses this third category of issues: things that Safari is doing
right, but it’s probably not what you expected. For some perspective on
why these aren’t bugs, check out my column “It’s your own damn
default” from July 2002.
Safari supports most HTML 4.0 features, but sometimes in different ways to the defaults of other browsers. There are some variations in default margins of block elements.
fieldsetelement, but doesn’t style it by default. This contrasts with the approach of Mozilla and IE, which is to draw a thin grey ridged border around it and add some padding. Be prepared to specify the styling of these elements fully if you want consistent presentation in multiple browsers.

fantasy. (This is on a Panther box with all the default fonts installed.) Bizarrely, Mozilla 1.6 users American Typewriter for both cursive and fantasy, while Firefox 0.8 users Apple Chancery and what looks like Trebuchet. Opera 6 for OS X users Apple Chancery and Comic Sans, while IE 5.2.3 uses Microsoft fonts Brush Script and Comic Sans if they are installed.

attr()syntax, or inclusion of arbitrary text files. However, it should be noted that Safari renders these in a different way to Mozilla-based browsers:

text-align. As noted by Safari developer Dave Hyatt, this is probably correct according to the spec, but it is not consistent with the behaviour of other browsers.
