Summary Whitespace between nowrap elements ignored after collapsed trailing space in ...

Reported 2008-03-07 08:01:50 PST
When placing two <span> elements with white-space:nowrap next to each other but separated by whitespace, under some conditions the whitespace is ignored and the two <span> elements will not wrap together when space is constrained. A test case is available, showing how minor changes can change this behavior.

In all the three cases, both the spans should be on separate lines .... rite ? Thats how firefox and IE display this file. Case 2 should be incorrect as well ?

Comment on attachment 191544 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=191544&action=review > Source/WebCore/rendering/RenderBlockLineLayout.cpp:3081 > + // If we allow whitespace collapsing 'word ' and 'word' are equivalent when before a whitespace > + // character, so treat both as a potential linebreak. Nit: I would insert a comma after "If we allow whitespace collapsing" and get rid of "when" in "when before a whitespace". > Source/WebCore/rendering/RenderBlockLineLayout.cpp:3082 > + checkForBreak = (ignoringSpaces || !currentCharacterIsSpace) && (c == ' ' || c == '\t' || (c == '\n' && !next->preservesNewline())); We should extract c == ' ' || c == '\t' || (c == '\n' && !next->preservesNewline() as a helper function at some point. > LayoutTests/fast/text/whitespace/inline-whitespace-wrapping-5.html:20 > + <span class="nowrap">xx </span> > + <span class="nowrap">xx</span> Please add a test case for bidirectional text.
