Welcome to the LimeSurvey Community Forum

In my opinion this is your concern.
The message that appears if the question is not answered in a valid way.
Here the manual says
However, if the user enters invalid data, the tips will appear. They will be coloured in red, getting changed to green once the validation criteria are met.

So, even if you "hide the tip" in case of an invalid answer it will be displayed.

@tapartner, thank you very much for the references. It helps!

@holch, Thanks for your reply.

I would like to change a few of the Validation messages and try to make them look softer for Kids community.

Say, a Required Field says, "This question is mandatory"

I would like to say, "Please fill out this field."

I do understand the reason of using PO lang file for Validation messages. LS is being used by vast community of people and it includes all standard Survey Validation messages to help us create a Survey very quickly.

That's my mistake that I have two Survey Forms (similar and imported), one is ACTIVE, and another is in DEACTIVE mode (for testing purposes). While posting my Forum post, I shared questions (Backend) from one Survey Form and Shared Answers/Validation (Frontend) from another Survey Form where I was experimenting with LS6.2.5 features  

Both of you pointed me out on this and I apologize for creating confusion in my post.

Thanks for your time.

Thanks for your reply. 

Sorry, I am using LS 6.2.5, and your reply for Mandatory and Soft has cleared a few of my doubts. I successfully compiled the PO and uploaded the MO in the host Lang > EN folder.

The last time I used Quick Reply in this Forum and so I didn't find any option to upload Images as attachments, so once you pointed out that uploading images locally is possible, I found the Main reply button under > Action button. So here I am now.

Your advice for hiding answers using CSS and then using ExpressionScript./ Yes, I have to do a little more research on ExpressionScript.

I am slowly getting a hold of this system. Overall, thank you very much for your answer. I appreciate your time on this.

Just a question:
What is your concern?
What I see:
You use an English GUI, probably a survey with base language "English", but use German answer options.
Furthermore your screenshot of the GUI shows a "mandatory" question, but the question itself seems to be "soft mandatory".

So what exactly is your goal?

And: 

I didn't find any "question validation" field anywhere?

In "Logic"
 

A very easy solution:
Hide the "question-valid-container" by css and insert your own messages into the question text with ExpressionScript.

P.S.
There is no version 6.5. (not yet). Please try to add the correct version.
Why don't you simply attach your images instead of using a separate file hoster?

 

Thanks for your reply.

I am using "Image Select List (Radio)" as Question Type.

I didn't find any "question validation" field anywhere?

The question looks like this: ibb.co/DQP9rzp

Survey backend: ibb.co/LYwHsLY


Why LimeSurvey has included Validation text as a part of the Language file, no idea. If updating the lang file becomes a blockage for future Lang updates, then it is a big issue even.

Overwring messages using JS inject is possible but again a difficult process for a simple change.

A thousand thanks!
I tried inserting in
multiple short text
First name
Surname
Tax ID code
E-mail
with validation equations e
two single choice (drop-down) for
Role
Credentials
It is certainly the methodologically correct way.
The problem now is what to insert in the individual CSS Class/s to have a clean screen like Joffman's

Please help us help you and fill where relevant:
Your LimeSurvey version: [6.5]
Own server or LimeSurvey hosting: [own server]
Survey theme/template: [vanilla bootstrap]
==================
I have created a Survey Form, and the Survey is already activated.

The question is, I am unable to locate the place where I can change the Individual Question Validation (Warning or Success or Tips) text messages. 

I wanted to change the Warning message to something new.

Kindly suggests the location of all these warning text messages.

A thousand thanks!

What @lfanfoni in the Italian forum explained may be this
 
 

Easy to implement, easy to validate

As you see it is one group with 4 questions
a. nome & cognome
b. codice
c. E-mail
d. the dropdowns

All merged with css classes "no-question" and "no-bottom"
Advantage
You validate each question separately.
All questions are mandatory.

And you show the groups accprding to the number of operators.

As @lfanfoni already mentioned your actual approach is not really usable in an online survey, it seems to be an adaptation of a paper-pencil questionnaire.
For online surveys you may read this

Insert it into the question text with surrounding curly brackets and you will see.

As I wrote:
You have your validation equation
 
copy it to the question text (with curly brackets)
 
You see that there is some HTML garbage, that might cause problems.
 

Here you only see THAT something is wrong, but not the reason.
 

Is there a simple way to do drop-down in the array text?

Rather simple.
There are dozens of examples in the forum. Just search for it.
But here one of the threads
