I think that you can realize that feature by adding this one line.

Mizuki ISHIKAWA, maybe it would be better to use a green tick icon which is used on other pages. What do you think about this idea?

I suggested #29053#note-1 because I did not have the idea of enclosing with a fieldset.
The green tick icon is used frequently on other screens, so I think that the layout you suggested is better.

By applying the following code, #29053#note-4 layout can be realized.
