OK fine, 
lss question in attachment

Sorry, I do not see any css in your question text.
 
and get this - obviously.
 

If I enter the snippet I get this
 
If you entered the snippet and it disappeared you seem to have no rights to do this.

OK thanks for your patience, LimeSurvey is fundamentally not my cup of tea but if my university makes things worse .... ^^'
Have a good evening then !

I don't think CSS can be forbidden from within Limesurvey (e.g. via the XSS filter).

So either this is an issue with a custom survey theme used by the university, or it was not implemented correctly.

Yes, you can.
I won't produce a video to prove.
But here

A normal user (with XSS filter ON)
 

In the sourcecode editor I enter
 
I "Save & Close"
I "Edit" the question again
 


The same in the HTML editor
 
Close the source code, still "maroon"
 
"Save & Close" and "Edit"
 
Gone.

No need to produce a video. I trust you on that one.

So either I had false information in my head or the XSS filter got stricter over the years.

I never use it on my installations, so I wouldn't notice. Good to know that it also filters simple CSS code.

Thank you Joffm for your maroon example, I've tried and very interesting, it works on the question text input (the question becomes indeed colored)
 
but when I preview the question, the style disappears, it becomes  
,

Should I contact my university to fix it ?
 

To be honest, the initial snippet didn't work for my LS6 either. Might be because in LS6 the exclamation mark seems to be a question mark. But I didn't have much time to test more.

Your installation seems to be LS5, so this might be the difference. Didn't have a chance to test in LS5, but I assume Joffm did so.

Can you show the code that you have put? Because this looks like limesurvey is trying to read it as expression script (instead of CSS), but can't find the variables.

If you could show the code when you put it, and then the code when you saved it and open it again?

My suspicion is that there is something wrong with the code used.

Could be that the XSS filter is deleting only parts of the code and that it deems "dangerous" and leaves other things, like the "color:blue;" part.

<span style="font-size:12pt;"><span style="line-height:107%;"><span style="font-family:Garamond, serif;">Quelle est votre année de naissance ? </span> </span> </span>
<style type="text/css">body {color: blue;}
</style>

But when I return on this question, the code becomes : 
<span style="font-size:12pt;"><span style="line-height:107%;"><span style="font-family:Garamond, serif;">Quelle est votre année de naissance ? </span> </span> </span> {color: blue;}
which does not work 

Here there is indeed a mistake in your syntax.
In javascript and css there has to be a blank after an opening curly bracket and before a closing curly bracket.

Otherwise Limesurvey takes it as expression.

Hmmm, setting the HTML body within a question doesn't make much sense for me. What are you trying to achieve?

So it seems like XSS filter is filtering the style tags and leaves you with just {color:blue;} and then everything in between the {} is interpreted like expression script.

What are you actually trying to achieve with this code?

Because the code you are using would attribute the blue color to all text ( www.w3schools.com/cssref/pr_text_color.php ) within the body-tag, which is basically the tag that surrounds the whole visible part of a website.

But in any way, it seems to be clear that the XSS filter is on and is filtering the style tags in your installation.
