I'm wondering if I can create multiple "brushes" in a single SVG file and use them thoughout my CSS.
Right now I have a single SVG file that has a gradient stored in the "defs" and a single rectangle that draws it. Then I use this SVG file as a background image in my CSS. It works well but I'd rather not have a million separate SVG files. I'd like to combine like "brushes" together in a single SVG file something like CSS sprites or XAML is capable of.
Is there a way to do this? If so what's the syntax to specify for the CSS background image which SVG element from the svg file to use?
Thanks for any help.
In theory yes, that should be possible. It's not yet fully defined in a w3c spec though and the implementations do differ at this stage.
Note that svg itself allows a special fragment syntax, so in theory you should be able to link to different views of the same svg file. That could be used to do CSS/SVG sprites.
Linking directly to the id of a nested svg fragment (or to any other element inside the svg) is something that would need to be further specified.
Assuming that linking with fragments from a CSS background property works, then a possibility if you use XHTML (serving the resulting file as application/xhtml+xml) is to just include the svg resources inline in the main document, eliminating the need for many separate files. This can be done as a pre-publishing buildstep if you wish to keep the svgs separate for editing. Another possibility is to use data uris.
I'm also seeking for the same, and here are the pointers I could find:
17.3 Linking into SVG content: IRI fragments and SVG views (w3.org)
SVG Stacks (simurai.com)
Can I use SVG fragment identifiers? (caniuse.com)
Better SVG Sprites With Fragment Identifiers (broken-links.com)
According to caniuse.com, there is an issue with browser support, but that does not prevent you to try and observe future browser evolution (in the hope a future day they will all support this obvious feature).

Does anyone know if I can separate each of the objects that the image has from an SVG file? Thank you
If the SVG is embed directly you can select each element/path object for styling/changes. If the SVG is added via img element you would need to save the SVG and embed it directly.
If using Adobe Illustrator it's easy to put each element on a separate layer with individual naming conventions to allow easy selection via ID tags.
Different paths in the SVG file should represent every individual image, hence you can extract the paths into separate SVG files.
I've been using Figma a lot lately to draw / edit images and export them as SVG files so I can quickly use inside my apps' code bases.
There's just one drawback with that: Looking through the SVG code to find out what element is what.
Up to this moment I'm having to go through the SVG manually in order to mark the elements (with classes or ids) so that I can manipulate them properly via CSS or Javascript, what's quite tedious :-/
It would be really convenient to be able to set an id or a class to each element (path, line, circle etc..) via Figma and have it reflected in the exported code, I strongly believe that there must be a way to do so...
So here I ask: Is there a way to set certain CSS **class** or **id** atribute in Figma and have it declared on the svg code that gets exported?
There's a checkbox "include id attribute" in the export section.
It inserts the element's layer name as the id attribute on the resulting svg tag.

I have concerns about placing big inline SVG vectors into html. Does this affect search engines and page rank? Corresponding to what you can lastly hear about Code to Text ratio. I believe inline SVG files should be treated like single line <img /> but I'm affraid it is not. Can anyone have some relevant knowledge how these are treated?
Of course the purpose i need place them inline is animation and styling directly by root css file.
I honestly dont think that this will harm you in the Search Rankings. Search engines would encourage the use of SVG over alternatives such as Canvas.
Google specifically indexes SVG, weather it is stand-alone or embedded into your HTML.
You can find a full list of file types indexable by Google Here
Here is a demo SVG file. Please use Firefox for viewing because currently it seems to be the only properly showing browser.
The task is to construct a pure SVG document (e.g. not html-embedded) that will be able to show tooltips using only CSS features (no JS and also no :before/:after pseudo-elements). I managed to achieve this by using the HTML foreignObject element.
However, I can not find if it is possible to position such elements in relation (e.g. 10px to the left and top from it) to other in-document SVG objects without using JavaScript for it and without embedding the SVG file itself into some other document format (e.g. HTML).
In the final version of the file there will be 20-30+ tooltips, so it is desirable to avoid manual positioning. I was hoping there would be something for "attaching" them to other objects (withthe use of their IDs) or at least to their parent objects, but my search results only return documentation and questions regarding JS or HTML implementations.
add. notes:
1) CSS-only SVG file is required because the file is intended to be used on wiki sites, which prohibid SVGs that have javascript in them.
2) If I understand correctly, displaying HTML formatting in HTML foreignObject element is not a current SVG standard requirement for SVG user agents (i.a. web-browsers). However, Firefox seems to properly display them, and Iād rather use that (even not fully supported) opportunity. If I am missing some easier ways of achieving the same thing ā please do tell about them.
3) SVG code backup: pastebin.
Unfortunately, you can't achieve this effect using just CSS because positions in SVG are attributes, not styles.
I would like to use SVG and not to have to create a PNG fallback every time. Is the an easy solution to this problem? I have looked at these projects but can't tell whether they support it:
http://sie.sourceforge.jp/
http://code.google.com/p/svgweb/
try GruntIcon - http://github.com/filamentgroup/grunticon
grunticon takes a folder of SVG files (typically, icons that you've
drawn in an application like Adobe Illustrator), and outputs them to
CSS in 3 formats: svg data urls, png data urls, and a third fallback
CSS file with references to regular png images, which are also
automatically generated and placed in a folder.
grunticon also generates a small bit of JavaScript and CSS to drop
into your site, which asynchronously loads the appropriate icon CSS
depending on a browser's capabilities, and a preview HTML file with
that loader script in place.
There's quite a number of SVG polyfills:

Please try them and update your initial question with the results for each.
