131031 2014-04-01 05:42:44 -0700 <pre> line-breaking (and hyphenation) rules overridden by inherited hyphenation 2022-07-13 17:13:41 -0700 1 1 1 Unclassified WebKit CSS 528+ (Nightly build) All All RESOLVED CONFIGURATION CHANGED P2 Normal --- 1 matkinson webkit-unassigned bfulgham oldest_to_newest 996237 0 matkinson 2014-04-01 05:42:44 -0700 Convention amongst browsers is that the <pre> element should not have any line wrapping by default, and browsers should not add any extra characters to its contents. Even if hyphenation is set on the <body>, it should not be applied to the <pre> element unless the user has explicitly styled the <pre> element (justification for this can be found below). This appears to be related to bug 67770 -- https://bugs.webkit.org/show_bug.cgi?id=67770 -- but is not quite the same situation (the applicable CSS is different), hence I am reporting it as a separate bug; hope that's OK. // Test Case (attached) The following browsers didn't wrap or hyphenate the contents of the <pre>. * IE 11 * Firefox 28 * Chrome 33 In the following browsers, wrapping and hyphenation inside the <pre> occurred. * WebKit Nightly r166560 (2014-04-01) * Safari 7.0.2 * Safari on iOS 7.1 // Expected Outcomes 1. The <pre> element should not introduce line-breaks as a result of hyphenation being set on a parent element. 2. The <pre> element should ignore hyphenation set on a parent element. // Justification for desired behaviour Why ignore an inherited hyphenation style? Because <pre> is meant to contain "preformatted text" according to the spec [1], which implies no further formatting is desired on the part of the content author. This also applies to line-breaks, as '<pre><code>...' is often used for computer code samples, whose authors expect that code could be copied and pasted from the browser; extra line-breaks would cause code errors in some cases. The spec also cites examples of ASCII art and free-form poetry, which would be affected similarly.

I don't believe there is any remaining compatibility issue. 228276 2014-04-01 05:43:23 -0700 2014-04-01 05:43:23 -0700 test case hyphenation-test.html text/html 439 matkinson PCFET0NUWVBFIGh0bWw+CjxodG1sPgogIDxoZWFkPgogICAgPHRpdGxlPkh5cGhlbmF0aW9uIFRl c3Q8L3RpdGxlPgogICAgPHN0eWxlPgogICAgICBib2R5IHsKICAgICAgICAtd2Via2l0LWh5cGhl bnM6IGF1dG87CiAgICAgICAgLW1vei1oeXBoZW5zOiBhdXRvOwogICAgICAgIC1tcy1oeXBoZW5z OiBhdXRvOwogICAgICAgIC1vLWh5cGhlbnM6IGF1dG87CiAgICAgICAgaHlwaGVuczogYXV0bzsK ICAgICAgfQogICAgPC9zdHlsZT4KICA8L2hlYWQ+CiAgPGJvZHk+CiAgICA8cHJlPkh5cGhlbmF0 aW9uIG9uIHRoZSBib2R5IGVsZW1lbnQgc2hvdWxkIG5vdCBiZSBhcHBsaWVkIGluc2lkZSBoZXJl LCBhcyB3aGl0ZXNwYWNlIHNob3VsZCBiZSBwcmVzZXJ2ZWQsIGFuZCBjaGFyYWN0ZXJzIHNob3Vs ZCBub3QgYmUgYWRkZWQuPC9wcmU+CiAgPC9ib2R5Pgo8L2h0bWw+Cg==
