Dear Forum,

I'm trying to change the arrangement of bootstrap button. I've tried some solutions in the forum. Neither adding a script to the question ( forums.limesurvey.org/forum/design-issue...p-buttons-vertically and forums.limesurvey.org/forum/design-issue...ntal-vertical-layout ) nor changing the CSS ( forums.limesurvey.org/forum/design-issue...otstrap-buttons-v3-x ) have any effect on how the survey answer buttons are arranged.

Since I have a very large amount of questions, I am looking for an option to change all at once using the questions' text or the CSS files.

Hi,
as you see, your links are broken.
You'd insert them as link with the link-button.

Now we do not know what you talk about.
How do you want the buttons to look like?

Here is an image of how it should like

Hi, I think I showed it a few weeks ago.
 
With a additional css class "mybtn"
Adapt the colors to your needs

Thanks!

However, I'm primarily looking for a solution on how to arrange the buttons in a vertical column. Do you have any help for that?

(PS: I'm struggling to send messages because the spam filter keeps refusing, even if the math is right..)

Do you think of something like this?
 
Always investigate with the webdevelopment tool of your browser (F12)

Now I set w-100 to 20%
