story.html vs story_html5.html

Jul 22, 2016

So what is the actual difference? I usually just use story.html and from what I can tell the only difference I notice is the html5 version seems to take a bit of a hit on resolution.

Hi Bruce!  Your course will intuitively play the best version based on the browser folks are using to take your course.  The requirements for viewing courses is here in our system requirements article.

More and more, as people are using mobile devices for their e-learning, course authors want to create the best experience for their learners.  This article describes publishing your courses for mobile devices.

And as far as the resolution hit, while we are focused on ever-improving our HTML5 output, you can read more about that issue here.

Which link is best to share the story_html5 link or the story.html link?  We are posting our content as continuing medical education and people may be viewing our content from different types of devices, OS and browsers.

Do people ever share both links so people can choose which one will be best for them?

Thank you,

Hi Carolyn!

We recommend sharing the story.html file. I'm attaching our documentation below that helps explain why.

Storyline 2 lets you publish courses for Flash, HTML5, and the Articulate Mobile Player app. To distribute your published content, upload it to your web server or LMS, then link to the story.html file in the published output. Here’s how Storyline determines which version of your content to display when learners view it.

Good morning. I'm publishing for LMS and in my Storyline output folder, there is:

  • index_lms.html
  • index_lms_html5.html
  • story.html
  • story_html5.html

I believe that we would link the LMS to the index_lms.html file for LMS courses. My question is why are "story.html" and "story_html5.html" included in an LMS publish, since apparently they are not used when importing a course into an LMS?

Please straighten me out. Thanks for any info you can provide.

I have published and the folder is created. However, the folder only has the following: html5, mobile, story_content --> folders and analytics-frame, meta, story --> files. I am referring to a course which asks me to make changes to the story_html5.html which is missing. Mozilla Browser and Windows 7 SP2 is the configuration. What is going wrong here?

Hi Gita,

I responded to a similar inquiry here.

For anyone following along, we simplified the published output in Storyline 360 builds 3.35.20995.0 and later. When you publish HTML5-only or Flash-only courses, Storyline no longer generates the following files in your published output:

  • index_lms_flash.html
  • index_lms_html5.html
  • story_flash.html
  • story_html5.html

You'll only see the files above when you publish courses with both HTML5 and Flash formats.
