WCAG 1.4.4 resizing text

We are trying to add a background (default and otherwise) to our theme. The image we're adding is sized appropriately for the 1010x600 screen. When we apply the background to a project, it stretches it outside the bounds of the default size of the screen (like 1550+ wide). Any ideas on this? Do we need to modify our image somehow?

Is there a way to change the size of the body text style? I'm wary of choosing heading styles for body text because of the risk of skipping heading levels and being less accessible as a result, but the body text seems a little too small. I can see how to edit heading level styles but not paragraph/body text.  

I have text which appears on screen by typing. Is there anyway to get the images to appear after this animation is completed. I cannot see any options to do this in Triggers or Actions without having to time it myself.   

Hi All,    Im creating a course for some, lets say, unruly teenagers and want them to be able to enter a username using a Text Input element.      Is there a way of making sure its only appropriate language used? 

I have a video in my Flow course that has an uploaded .vtt file for closed captioning. It works great on a desktop, but there's no cc text option on a phone....just the transcript. Is there a setting to allow the cc text on a phone?  Thanks  

Is there a way to bypass the pre-test based on an assigned variable (either custom or system) when I learner indicates that they are a new hire employee and force them through all of the content? If the pre-test cannot be bypassed, is there a way to make their score null/void so they are forced through the content based on the variable that says they are a new hire?  

I've read the guide it says to right click another place it says double click neither works in dominknow. At the bottom of the screen I see Accessibility tab with Alt Text and a fill in but can't find a way to made the grayed out Edit Asset button work.

"I have a page with a lot of text and four links. While clicking on these links is not required to proceed to the next page, I want to set up the 'disable previous' page and 'enable next' page buttons on this page. This means that visitors will have to scroll down to the end of the page before the next button becomes available and they can proceed. I'd like to avoid using the navigation functions on the ribbon pane, if possible, and just use triggers or actions. 

Instead of using the Transcript button in a Flow Navbar, we'd like to insert a "Show Transcript" button onto pages that make use of the Page Transcript functionality.  This works just fine, but we cannot determine how to change the look and feel of the modal that displays when the button is selected.  It defaults to a gray background with white text which does not align with WCAG color contrast.  There also seems to be excessive padding that we'd like to overwrite.  Can you please point us in...
