Default SVG style

What is the default SVG style ? for example, what is the default开发者_运维问答 font of a new SVG document ? Is it described in the SVG spec ?

<svg><text x="10" y="10">Hello</text></svg>

Thanks

Go here and scan the page for the string "Initial:". Then you find any initial values the spec defines for text rendering. For font-family it states however:

'font-family'
    Value:      [[ <family-name> |
                    <generic-family> ],]* [<family-name> |
                    <generic-family>] | inherit
    Initial:    depends on user agent
    Applies to:     text content elements
    Inherited:      yes
    Percentages:    N/A
    Media:      visual
    Animatable:     yes

That means, the user agent may decide, which font family to use, if none is given, or if it cannot access a font with the given name.

Overall initial values: The spec defines initial values in every case, where you can write an attribute as CSS declaration (like fill: red;). In this case the behaviour is like the one CSS defines.

In some of the other cases there are fallbacks defined, but it depends on the case.

Well, I've not tested it myself but according to SVG Specs 1.1 Font Description, there's no default font (font-face/font-family) mentioned. It does stated this:
"The 'font-face' element corresponds directly to the @font-face facility in CSS2"

Well, I would assume it should take the parent container's font if specified. If there's none specified on the parent or no parent, I guess it'll be the browser's default font or the viewer's. Don't quote me though. :P
