Refactor simple-hint bar

[Aljullu]

This small PR fixes some issues:

• The text and the buttons of the #simple-hint bar were not aligned.
• When the window was small, the buttons were breaking in different lines.
• In the code, 'No' button was before 'Yes' but visually it was the other way around. Now 'Yes' is always the first button, so people with screen readers get the buttons in the same order than users using a screen. It also makes keyboard navigation more logical.
