@Harish, look at this, it's not great, but I guess it would give you an idea, I haven't been coding web for long, so bear me if it's ugly : )

Link your code with the question if you want people to help, it's hard to imagine what you're trying to accomplish just by reading the question : )

We need to get a reference to the label for the selected radio button to change its background color, I don't know how to do it, the label is not linked with the radio button, what do you think? got any ideas?

@Harish check the code again, I made some changes...

Well, you can try to use buttons if you want to, it's your choice...

The reason of the submit button is to allow the visitor to change their choice before processing if they changed their mind. You can choose to directly submit the choice when visitor click on one of the choices, without submit button, but it means visitors need to be careful in choosing, because they can't change the choice once the choice is submitted.
If you want button in place of radio button you can use multiple submit buttons, once either one is clicked the form is submitted. That's just my idea...

@Harish, multiple choice in the lesson appears to be using radio buttons (cmiiw), the thing that worries me is that if we use JavaScript to change the choices appearance than the visitor can view the source, and can figure out the right answer by checking which choice will change the background color when clicked.
I guess this is also the reason why SoloLearn only allows game in the app.

I'd suggest you create a function in php or JS and store it in a diff file and then call it whenever needed.

Yes, just edit CSS for radio buttons' label
.rlabel{
display:block;
border:#c0c0c0 thin solid;
background-color:#abcdef;
}
I guess it's possible, but it means the visitor cannot change their choice, with the button visitor can still change their choice before submitting if they weren't sure of their choice.

if $x == $xyz {
echo ' <body style="background-color:green">'
}
This should work

implement my whole ans in HTML, its the same, the echo should do the job there
