Hi,
This is a quote from Section 4.2 of the spec:
"A style sheet in the context of the Document of an HTML parser or XML parser
is said to be a style sheet blocking scripts if the element was created by that
Document's parser, and the element is either a style element or a link element
that was an external resource link that contributes to the styling processing
model when the element was created by the parser, and the element's style sheet
was enabled when the element was created by the parser, and the element's style
sheet ready flag is not yet set, and, the last time the event loop reached step
1, the element was in that Document"
And the section about parsing - the "<script>" tag says that before executing a
script the parser must:
3. Spin the event loop until there is no style sheet blocking scripts and the
script's "ready to be parser-executed" flag is set.
I have two questions:
1. As far as I know, Firefox and Webkit have a "stall on demand" behavior,
where a stylesheet blocks a script only if the script asks from style
information. According to the spec the style sheet always blocks a script, am I
right?
2. Can you clarify the condition - "the element's style sheet was enabled when
the element was created by
the parser, and the element's style sheet ready flag is not yet set,
and, the last time the event loop reached step 1, the element was in
that Document"
Does it mean the style sheet blocks scripts only if it's currently being parsed?
Tali
