I want to use some of the new features of HTML5 in surveys created with SSI Web 8. How do I do that?
By default, SSI Web 8 uses the HTML4 mark-up language because it is supported by nearly every browser. However, as the browser providers begin adopting the up-and-coming HTML5 standard, there are many improvements in the language that can increase the functionality and simplify the development of surveys, especially if you create lots of Free Format questions or use HTML markup.
If you want to use HTML5 in SSI Web 8 and later, you may. All you need to do is change the HTML DOCTYPE attribute to
<!doctype html> in the Survey Settings > Advanced tab. Then your survey can use the HTML features, assuming they are availabe in the respondent's browser. This website, by they way, is written in HTML 5.
