How to add a text beside a bipolar matrix table

Nahed
You can do something like this via javascript/custom coding by hiding all other elements (if this is needed) and just showing the middle one or if you want to place text somewhere else you can unhide that text. or you can simply add a space in all other question texts and just write text in this one.
Hope it helps!

Thank you for your answer. If I am not wrong, I have done what you suggested: including the text only in the middle and discarded in the other lines. T
he problem is when including the text in the left side, that line becomes too large compared to the others.
Please find attached a picture that illustrates the problem.

I believe if you add it right in the middle of the 11 rows you will see it center aligned. Also, try and include the image one row above and the text in the row below, not together. The container will still take some space.
Also, you can control that additional padding via CSS by adding it to your custom CSS -> look and feel. Something like this:
.Skin .Matrix th {
padding: 0px;
}
Hope it helps!
