I want to put the logo of math.SE to my website linking to my profile, and the template I'm using uses svg versions of the logos; at least if I have the svg version of a logo, I know how to use it in my website, so

How can I get the *.svg version of the logo of math.SE ?

  • $\begingroup$ On the main site, If I right click and save the logo (I assume you mean the one with 6 red squares plus the text 'Mathematics'). It is an 286x32 svg.... $\endgroup$

  • $\begingroup$ So using a vector image editor like Inkscape, one can extract the site's logo. $\endgroup$

    $\begingroup$ You can also find the logo in these posts (although not in svg format): Design Ideas for Mathematics Site and Do those red cubes aligned circulary next to MATHEMATICS have any mathematical significance? $\endgroup$

    $\begingroup$ @MartinSleziak see for example meta.stackexchange.com/questions/22117/… This should apply to math.se too (MO is different). $\endgroup$

It seems that svg-file with the logo is available here: https://cdn.sstatic.net/Sites/math/Img/sprites.svg?v=fa2277060fb6
I got the link after choosing "Inspect" and "Sources" in Google Chrome, while viewing the site.

It seems that svg format is not supported as a format which can be used in posts. So here is at least a screenshot showing the content of the svg file:

sprites

You can also find the logo in these posts (although not in svg format): Design Ideas for Mathematics Site and Do those red cubes aligned circulary next to MATHEMATICS have any mathematical significance?

As mentioned in the comment, you should keep in mind copyright/trademark issues. See also: What are the rules on using the Stack Overflow logo?, SO page with logos and Guidelines for the Use of the Stack Exchange, Inc. Trademarks.

Since you have mentioned that you want to use this to link to your account, the fact that flair can be used for this purpose should be mentioned.

(Both these issues were raised in the comments by quid - I think they are important enough to be mentioned in an answer.)

If you want the Mathematics logo, I cut down the svg HTML code to be:

Let me know if it works, because it works for me, but I don't know if it will work for others. Otherwise if you want all of the other details, follow Martin Sleziak's answer.

TIP: If you would like just the logo and not the "Mathematics" letters in there, just remove the first "< path>" line.
