So, at their core Experience Views are simply HTML/CSS with Handlebar templating support.
If you’re new to Experiences, I highly recommend the Experience Views Walkthrough.
For now, I think I’m interpreting this question as, where do you put the assets you’ve just received from Bootstrap Studio?
Well, you just receive a bundle of CSS/HTML/JS.
HTML - In Losant, you can’t upload HTML directly, but you can create an Experience View and copy/paste your HTML there. Then, using an Experience Workflow, you can pass data to that page and display it using Handlebars.
CSS/JS- Right now, you have two options to store CSS/JS in Losant.
- View Component - You can create components for your assets and pull them into an experience view. Here is an example:
-
Losant Files - You can simply upload your files to Losant, and reference them in the respective
scriptorlinktag in an Experience View (HTML).
Let me know if this helped. Happy to explain further.
