Thank you for your quick reply. I replaced

Sorry. Missed that.
You actually need to target #SkinContent instead of .Skin .SkinInner. Try this:
#SkinContent{ width:100vw; } .Skin .QuestionOuter.Matrix{ width:100vw; max-width:100vw; }

Thank you again for your additional support. I tried your code, but it had the same effect as before. The survey interface is shifted to the left or right, but its width remains unchanged. Is there any other way you could think of? I find it quite hard to believe that Qualtrics users did not have a similar inquiry in the past.

share you survey link. I'll see what the issue is.

You can access a dummy survey of what I intend to do here: Survey
I used your latest CSS code and replaced 100vw by 200vw in all instances to test the effect on width. As you will notice, the width of the Likert items was not affected. You still need to scroll to the right to see the 7th answer choice.
Thank you for your help!

Add this:

.Skin .QuestionText{max-width: 100% !important}

Thank you!

.Skin .QuestionText{max-width: 100% !important}

Dear all,
Thank you for this discussion which has already made me go a little further in solving my problem! I experience the same type of problem with matrix questions : participants have to scroll to the right to see all the 9 answer choices from the matrix. Like Svante, I would like to avoid that and display all the option on the computer screen at once, without requiring the participant to scroll. I have tried the CSS codes you shared in this discussion, but it's something I don't master and so I imagine that there are some modification to make in these codes since in my case it's a matrix and not a likert scale. I tried this :
#SkinContent{ width:100vw; } .Skin .QuestionOuter.Matrix{ width:100vw; max-width:100vw; }
Skin .QuestionOuter.Matrix{max-width: 100% !important}

But I don't really understand these codes and all it did was shifting the survey interface to the left and increase the width of all other questions (e.g. multiple choice questions), except my matrix... Does anyone have any idea how to also (or only!) displaye matrix entirely on the screen in order to see all the 9 scale points?

Thank you very much for the help already provided in this discussion! I am looking forward to your responses.

Dear all
Any update on CBlaison's Question? I am having the same display issue with 7 points scale. The question type is Matrix Table.

https://community.qualtrics.com/XMcommunity/discussion/comment/41373#Comment_41373Any answer to this please? I have the same problem - a large matrix question still requires scrolling. Also, I would like to prevent anything displayed wrongly on mobille after the change. Thank you

https://community.qualtrics.com/XMcommunity/discussion/comment/51876#Comment_51876Adding a question:
I would like to use the 100% settings for mobile, but around 80% of vw for desktop. How do I do this?

Hi there! 

Can someone please advise how I can change the layout for the ‘Form’ questions so the options are not shown in the multiple lines. (I have the same question for the ‘Pick, group, and Rank’ questions as well.)

See the image below for clarity.

Thanks!

I just wanted to add to this discussion something that combined multiple suggestions that I read on this forum. I don’t know if this exactly addresses people’s specific questions above, but this worked for me. I wanted the width of my survey to be wider, and also not have individual questions have a scroll bar at the bottom. So in the custom CSS, I included both of these two lines:

.Skin .QuestionText{min-width: 1000px!important;}
.Skin .SkinInner {min-width: 1100px!important;}

You can change the numbers depending on the width of your screen/survey. But the important thing is that the number in the first line (here, 1000px) is slightly smaller than the number in the second line (1100px). The first line controls the width of your question; the second line controls the width of the box that bounds your survey.
