My client would like to use Gotham Rounded font in survey.

Whether Gotham Rounded font is supported by most browser? How could i add a new font to survey?

Kindly advise.

Thanks very much!

There are a few problems around fonts (not a Limesurvey problem, but a general WWW problem).
People might not have installed the font that you want to show, which means they can not see it and it will be substituted by any font. This often looks pretty ugly.
Now there are a few options to solve that. You could upload the font to the web and reference it from there. However, there are often licencing problems, so watch out. Make sure that you are allowed to upload the font. Gotham seems to be a comercial font and even if you have it legally on your computer, it doesn't mean you can use it legally on the web. But looking here www.typography.com/fonts/gotham-rounded/styles/ it seems like the web use is free. So have a look at this website.
Probably it uses some webfont tecnique or something.

Thanks so much for your prompt reply.

I have visited the website you shared. I tried to download the Gotham typeface used for web application but failed. Do you know what is the format of font they offered? is it in .ttf ?

besides, how could i incorporate the font to my existing limesurvey application. I am using version 2.05 for now.

Sorry for so many questions. Much appreciated if you could revert. Thanks!
