Scalable Projects: you can publish a blank (normal) project to HTML5 with the option 'Scalable HTML Content' activated.
This will not result in a real 'responsive' project, because the layout will be the same on all screens. Another word sometimes used for this type of project is 'adaptive'.
- Responsive Project with Fluid Boxes which is the work flow introduced with CP2017. I see the result as a solution between the Scalable HTML projects (same layout on all screens) and a esponsive project developed with Breakpoint views. Such a full responsive project can have different layouts for diferent screen sizes corresponding with the Breakpoints. When using Fluid boxes the layout will be rearranged by the application depending on the screen size and the settings. Some items can be left out for small screens but you will not have full control over the design for each size. Moreover there are some limitations which I will explain later on (with possible workarounds and tips). Developing time for this type of project will be in between time needed for scalable project and for a Breakpoint Views project. Fluid boxes have a great way to make font size changing in a 'fluid' way.
- Responsive Project with Breakpoint Views is available since version 8. It is no longer the default approachn when starting a responsive project. You have to switch to this workflow from the Project menu.
Titlee: not all images which in the Breakpoint example could be used on the Fluid Boxes version because you cannot stack items. I could have combined the images in a graphical application to have one image for Fluid Boxes, but the different effects and timing didn't have a workaround.
The images used for the mobile screen (Breakpoint) are different and smaller than for the other breakpoints. Not so for the Fluid Boxes example.
Buddies: similar: the ruler cannot be used for Fluid Boxes, at least not when stacked with other images.
Content: different items can be clicked to show more information. For the Breakpoint version that information is stacked and Hide/Show is used. Text and images are combined in a group. For the Fluid Boxes I used the workaround by creating one object with different states. Grouping is not possible here.
- Comparison: maybe less apparent, but I used an effect on a group (image + shape with text) for the Breakpoint view version, since grouping is not possible for Fluid Boxes I had to use separate effect on the items.

Limitations and workarounds - Fluid boxes
Grouping of objects is impossible
That is not only disappointing for management of crowded timelines, but it also means that group effects are impossible. THse group effects can be very useful, look at this article.
A widespread workflow consists in having different texts, grouped and stacked in the same location. Based on a click to show one out of the group can be done with a shared action with two commands: first hides the group, second shows one text. That work flow is impossible in fluid boxes. You'll have to create duplicate advanced actions with a lot more commands.
Lightboxes are also impossible with fluid boxes.
In many cases a workaround is possible by using one multistate object instead of the group. In the movies for which I posted the links, that approach has been used on slides 3 and 4. Compare both movies. A multistate object can also be an alternative for objects appearing staggered on the timeline, but in the same location. Using an On Enter action with the command Delay Next actions can be a workaround (see Autolists).
- It is not possible to have an object timed for the rest of the project
This is often used as alternative for objects like toggle shape buttons or a logo on the master slide. Since such a object has a unique ID, it can be controlled, hidden on some slides and shown on other slides. Controlling objects on master slides is not possible because they do not have an ID. You'll need perhaps more master slides when working with Fluid Boxes as workaround.
- Some types of objects cannot be used: Zoom object, mouse object, highlight box, click box over another object and line object.
Many users still stick to the the old work flow of putting click boxes over images to create a hotspot. Workaround is to use a shape filled with the image, a workflow that is available since many years but apparently not well-known.
For a highlight box: use a shape as well with multistates, one having a thick border and eventually a semi-transparent fill. No workaround however for the outer fill which exists only for a normal highlight box.
The Line shape is a rebel, often causes issues (only shape that cannot be rotated in Options). You can replace it by a rectangle with a minimum width of 4 px which is the minimum.
Do not misunderstand my post, because it sometimes looks like I don't like Fluid Boxes workflow. It is a great way to create responsive projects in much less time than with Breakpoint views, but you need to be aware of what is possible. I am confident that some of the present limitations will disappear in future releases. Use your design skills and knowledge to judge if a project is suitable to be developed with Fluid Boxes or if you need Breakpoint Views workflow.
If you like Fluid Boxes, do not hesitate to enter feature requests for those present limitations that bother you most of all. It will be a big help for the Adobe Captivate team.
